Purpose The purpose of this paper is to investigate the relative importance of project management (PM) competences across the different stages of a software project life cycle to identify competence development gaps and opportunities. Design/methodology/approach A deductive and quantitative approach was adopted to address the research questions with a web-based survey for data collection. Findings After reviewing the context of competences and PM competences, the importance of the PM competences overall and for specific stages in the project life cycle was analysed. The result highlights that functional and meta-competences are perceived to be the most important competence dimensions for software project practitioners. Originality/value This study makes three contributions. First, it consolidates PM competences into a set of 20 within four competence dimensions. Second, it prioritises these competences across the software project life cycle. Third, it identifies the significance of the inter-relationship between PM competences and project life cycle to reveal PM competence development gaps and opportunities.

Agile project management methodologies are becoming more popular day by day. They provide flexibility and adaptability to customers and project teams in terms of planning and competition. Due to these benefits, the share of the agile managed projects has been increasing. Most of the agile projects are executed on products. On the other hand, every product has a life cycle. Just as living beings, it is born, it grows/changes, matures, loses ground and completes its life and dies. The stages that define the product life in this way were put forth in The Product Life Cycle Theory. One or generally more projects and various operational works accompany the product throughout the product life. In this study, the effects of applying agile project management principles on product's life cycle are analyzed. In order to receive effective results from the agile project that accompany the product, project is suggested to be divided into phases and these phases are proposed to be differentiated according to the stage of the product. Furthermore, Product Life-time Project concept is introduced with agile methodologies. It reserves a project and its team to a specific product during its whole life. Product Life-time Project is applied to software development and automotive industries and the results are presented and compared with the traditional approach.

Full textAbstract:
This article discussed the problem that is commonly faced by project managers in selecting an appropriate software development model. A good number of models and the ongoing debate between the advocates of agile and traditional models make the selection of a right one uneasy and complicated. The purpose of this study is to propose a new alternative view in selecting development models from the perspective of degree of flexibility in different project situations. The results of a survey conducted to 74 project managers and software developers indicate that there are three naturally occurring development model groups, including heavyweight (Waterfall and V models), middleweight (Incremental and Spiral models), and lightweight (Extreme Programming and SCRUM). A canonical function is identified to help project managers select an appropriate software development model for each potential or planned project.

Purpose – Software development life cycle (SDLC) has always been the core methodology for any software engineer that depicts the entire development process which an organization is bound to utilize to achieve successful software. The purpose of this paper is to bring forth a conceptual model after analysing the best practices in SDLC, and extracting the best out of agile methodologies and the open source software, thereby bringing forward an optimised structure. Design/methodology/approach – The OASDLC is hypothesized specifically for “Brihaspati” project and is formulated keeping in mind the gaps and limitations posed by existing SDLC models. OASDLC is further put to test for achieving lower costs and efforts involved. The tests are further substantiated by means of hypothesis validation through execution of a survey based research. Findings – It has been observed that the present conceptual model further optimizes the efforts involved while adopting such a practice. Originality/value – This paper proposes a novel SDLC model so as to achieve a best practice for a software project. On analysing the issues involved such as tight budget and timelines, it led the authors to formulate a newer concept “Open Agile Software Development Life Cycle model” (OASDLC).

This article aims to provide the reader with a comprehensive background for understanding current knowledge and research works on ontologies for software project management (SPM). It constitutes a systematic literature review behind key objectives of the potential adoption of ontologies in PM. Ontology development and engineering could facilitate substantially the software development process and improve knowledge management, software and artifacts reusability, internal consistency within project management processes of various phases of software life cycle. The authors examined the literature focusing on software project management ontologies and analyzed the findings of these published papers and categorized them accordingly. They used qualitative methods to evaluate and interpret findings of the collected studies. The literature review, among others, has highlighted lack of standardization in terminology and concepts, lack of systematic domain modeling and use of ontologies mainly in prototype ontology systems that address rather limited aspects of software project management processes.

The materials of the article analyze the main models of the software life cycle, which underlie the flexible methodologies of software development to identify the features of its application during the implementation of team projects. It was found that the use of classical life cycle models, in particular, cascade, spiral, incremental, V-shaped and iterative, is not effective in implementing all modern aspects of software development based on the use of new information technologies. It was conducted the comparative analysis of the most popular flexible methodologies of software development Agile, Scrum, Kanban, RUP, DSDM, RAD on such indicators as life cycle model, number of iterations, purpose of project creation and types of projects for implementation, priorities, possibility of interaction with the customer, adaptation to change. The advantages and disadvantages of flexible software development methodologies made it possible to single out the MSF methodology, which is based on the harmonization of cascading, spiral and iterative models of the software development lifecycle and allows you to choose the Scrum template as the most successful for implementing and demonstrating work in team development projects. MSF uses an approach that involves the gradual creation of a working product with some functionality that reflects the requirements for the final product at this stage. It is proposed to use Microsoft solutions based on Visual Studio and Team Foundation Server for centralized management of team project elements, use of visual architecture modeling tools, code quality management capabilities and obtaining all project team members up-to-date information on project status. This is because the MSF model combines five following main models: team model; process model (sequence of actions required to build a team project); discipline of project management (provides comprehensive planning of all stages of the team project, budget management, resources, costs, scheduling); risk management disciplines and readiness management disciplines (assessment of team project members' knowledge for further distribution of team roles). The article demonstrates an example of creating a training team project based on the use of the Scrum flexible methodology template in Visual Studio based on Team Foundation Server.

Abstract Where does risk management belong, at the beginning of a project or at the end? Many managers choose one or the other, or both. The correct answer is that risk management needs to be considered throughout the software development life cycle. When the risks include the safety of patients or the users of the software, the methods need to be more formal. This article will explain why, and then will provide the how and the how much.

Purpose – The main objective of this article is to propose the use of a model developed by Matturo and Silva (2010) to capture knowledge in software projects based on the lessons learned.Design/methodology/approach – We carried out a qualitative research from a descriptive perspective through a single case study applied to an Enterprise Information Technology company. The company is a leader in market solutions to support customer experience management. For the data collection process, we used systematic literature review, document analysis and semi-structured interviews.Findings – The results supported project managers to better understand the storage and use of information from lessons learned in dimensioning the use of human resources and to support the estimation of new project activities. In addition, the results showed the organization's disregard for not giving due importance to the information and knowledge generated during the life cycle of a project.Research, Practical & Social implications – The model allows companies to obtain new knowledge or consult existing knowledge throughout the life cycle of projects and to support project managers in the process of estimating activities and preparing budgets with greater precision, using the information from lessons learned as a support. acquired in the completed projects.Originality/value – The lack of information in the initial scope of the project and in the definition of activities in the human resource allocation process hinder the duration of the project's development activities, directly resulting in inaccurate estimates. As a result, this scenario contributes to the increased risk of deviations in terms and / or costs of software projects.

Deciding when to stop testing and deliver or release a software product in the competitive market place, is an important decision in software project management. Software tools are available in the market for backing the decisions of project managers with regards to software release. Also, software development houses may need to know “for how long should they support and maintain their software product after release?” A few tools are available that take into account the software product support activities that go beyond software release while computing and optimizing software life cycle cost. A simulation based approach has been devised for helping Software Project Managers in deciding: 1) How long to test software? 2) How long to provide free support to the product? 3) When to withdraw the product support?

Among the various steps in the life cycle of software development, system requirement management is an essential but often neglected step. Comprehensive requirement management can not only help developers to work on a system to meet the requirements of a project, but can also play a vital role in the communications among stakeholders. In general, natural languages are often used to describe and record user requirements; however, this results in ambiguity, inconsistency, imprecision and incompleteness. To increase the accuracy of requirement modeling and analysis, it is important to have appropriate management methods and tools such that the requirement engineering process can be supported within the project. In this work, we propose a System Modeling Language (SysML)-based requirement management methodology to assist in the collection and the modeling of user requirements. We also provide a convenient procedure and a prototype tool to model, analyze, validate and verify the recorded system requirements, and consequently to ensure that the system can satisfy users’ requirements.

Major elaborations on sustainable development relating to the general economic sphere of various issue-related areas. Surprisingly little explicit guidance presenting this topic from the organizational side exists. To fill this gap, this paper attempts to propose and verify the concept of a sustainable approach to IT project management by involving the client at the stage of choosing the project management methodology. The research scope constitute IT projects, the subject of which was the development of software commissioned by the organization. The study aims to assess how the internal perspective of sustainability in IT projects, manifested in the matching of IT project management methodology to the client, affects the overall client’s satisfaction with the IT project, its products, and results. In the study, 64 IT projects implemented in Polish SME organizations were analyzed throughout their life cycle. The study has proved that introducing and improving the internal perspective of sustainability in IT projects, by matching an IT project management methodology to the client type is one of the key factors determining the level of client satisfaction and thus the assessment of the project’s success. The evaluation was made using the Servperv method by developing a measurement instrument dedicated to the IT project management area. Researches can use the proposed approach and the Servperv measuring tool to carry out similar analyses with different sample groups across other countries. The software industry can find results valuable and useful with regard to the IT project management improvement.

Construction projects require a significant amount of money and other resources in order to carry them out in an effective way. Cost control is a critical step in ensuring the success of the project and increasing its value. Nowadays, the large-scale application of BIM technology has ushered a technical change in the development of construction projects, which has greatly increased the level and efficiency of project management. Due to BIM technology, the construction engineering quality is significantly improved which really helped in obtaining the social and economic benefits. However, the BIM technology in our country is started relatively late and the technical force is not strong enough; then correspondingly, we must deal with many problems in the process of developing and using BIM technology based projects. In view of the fact and to address this issue, this paper establishes a three-dimensional architectural model based on the relevant information and data of the construction project using the BIM technology. The proposed model optimizes the clustering of construction project information data and adaptively configures the whole life cycle process of the construction projects. In addition, the performance of the proposed system has been compared and tested with the other systems as well which shows how good the proposed system is, as compared to the other systems. Further, the proposed model makes the artificial intelligence efficiency of the project management better. The simulation results show that the model not only has good access and query capabilities but also greatly improves the intelligence level of the project management.

The Whole Life Cycle Engineering Costing Management is an effective method to minimize the cost of an engineering project for the whole life, including the construction period, the operation period and the removal period. In this paper, we divided the Engineering Cost into three parts of labor costs, material costs and machinery costs. We have built a River-influx Model to calculate the social discount rate for the future, based on historical data and using MATLAB software to fit curves. We can then calculate the whole Life Cycle Engineering Cost for the future.

Automobile, aerospace, and other industrial manufacturers have evolved over the years to use a multitude of computer-aided design (CAD) and product data management (PDM) systems and have long depended on single-vendor solutions to support their enterprise-wide engineering activities. Increased product complexity, distributed authoring environments, and the need for tighter team integration with partners and suppliers have created challenges and new opportunities for information technology (IT) vendors to be able to integrate systems from multiple independent software vendors (ISVs) to form a coherent Enterprise PDM system. This paper will describe, in detail, a case study and solution of an IBM Research project called Hedwig. Hedwig investigates creating robust solutions for Product Life-Cycle Management (PLM). We focus on several research issues, including information federation, data mapping, synchronization, and web services connections. We describe a working system that allows access to several heterogeneous PDM systems that are used in the automotive and aerospace industries.

The current state of the practice in bridge management highlights a growing need to develop scalable optimization software tools to support the development of truly optimal bridge improvement programs and ensure that limited financial resources are optimally allocated. The heuristic project selection approaches employed in today’s bridge management systems are not capable of generating optimal programs. Agencies that rely on suboptimal programs may inadvertently direct a significant portion of their budget to the wrong projects, leading to an increase in maintenance backlogs and overall system risk levels. The subjective project selection criteria may also hinder the ability to quantify project benefits or justify projects to funding agencies and stakeholders. This paper presents a novel dynamic programming–based multiobjective optimization approach that is capable of generating global optimal network-level, long-range bridge improvement programs. The algorithm considers three objectives: the minimization of system-level risk, the maximization of system-level condition, and the minimization of life-cycle costs, subject to agency-defined constraints and planning scenarios. The algorithm efficiently explores the enormous search space to find optimal project lists for each year in the planning horizon under any given scenario. Alternative planning scenarios are defined to quantify the impact of different investment levels on system-level performance metrics and to determine the investment required to achieve the desired performance and risk targets.

Owners and construction management are in permanent search to increase competitiveness, reduce cost and time and maintain a high quality of products and services. In this objective project management tend to organize work execution by implementing comprehensive, linked and sequential processes, making full use of every work effort and limiting work duplication and rework. Since the ’90s, the 3D-modeling is used to coordinate, plan, build and manage future structures. The BIM approach proposes to stakeholders to participate in an intelligent centrally shared 3D-model making use of every contribution to this model, facilitating the coordination, solving the interfaces, reducing duplication efforts and carrying the developed data information throughout the life cycle of the structure and beyond the construction phase. Completing a complex structure requires an important level of design management and coordination of the interface between architect, designer, mechanic, electrician, and other designers. Basic input is required from equipment suppliers. Now, for a good reason, everyone in charge of the process is focused on achieving their process with less cost and less time. Thus, he inadvertently reduces the effort associated with surrounding or subsequent actions, and focuses on his main result. For example, structural engineering developing a 3D-model will focus on clean structural design focusing on structural continuity, geometry identification, and calculation model for finite elements of software. Likewise, a mechanical engineer will model plumbing and mechanical networks for fabrication and installation purposes. It is the same with other design disciplines.

The article is aimed at disclosing the possibilities of using the simulation modeling apparatus in the management of the development of projects of product IT companies. Based on the analysis of a number of literary sources, an overview of research in the field of IT project management is carried out and the existing status of application of the simulation instrumentarium in the solution of applied tasks is described. The compliance of simulation technologies with the special requirements of the tasks inherent in the processes of software products development is substantiated. According to the life cycle of software creation, a brief characterization of the typical stages of project promotion is provided. A simulation model is proposed that reproduces the dynamics of the deployment of product projects of IT companies. The model is built using a hybrid approach – a combination of discrete-event and agent-based methodologies – on the software platform for multi-platform simulation AnyLogic. The discrete-event approach provides a high degree of detail of the processes being modeled. The agent-based approach allows to define the project as a dynamic unit with specific properties, which makes it possible to take into account the peculiarities of products ordered by consumers – clients of an IT firm. The model’s work is demonstrated by the results of standard and optimization simulation experiments implemented on conditional data of an average product IT company. These situations prove the possibility of using the model as a platform for making managerial decisions by the head of the product project development team. The model is presented as a simulator with the modular, open architecture and parametric adjustment for specific conditions of experiments. It may be recommended for product IT companies to practice management of the projects of software development.

Software Estimation gives solution for complex problems in the software industry which gives estimates for cost and schedule. Software Estimation provides a comprehensive set of tips and heuristics that Software Developers, Technical Leads, and Project Managers can apply to create more accurate estimates. It presents key estimation strategies and addresses particular estimation challenges. In the planning of a software development project, a major challenge faced by project managers is to predict the defects and effort. The Software defect plays critical role in software product development. The estimation of defects can be determined in the product development using many advanced statistical modelling techniques based on the empirical data obtained by the testing phases. The proposed estimation technique in this paper is a model which was developed using Rayleigh function for estimating effect of defects in Software Project Management. The present study offers to decide how many defects creep in to production and determine the effort spent in months. The estimation model was used on Software Testing Life Cycle (STLC) to complete product. The accuracy of the model explains the variation in spent efforts in months associated with number of defects. The model helps the senior management in estimating the defects, schedule, cost and effort.

PurposeThis paper searches for integration methods proposed by different authors that assess the life cycle of a building using models of building information modeling (BIM) and it also compares and discusses them.Design/methodology/approachSystematic literature review (SLR) is selected as the main research method of the present paper, aiming to collect and critically analyze multiple research studies. This paper is not only limited to studies where the whole life cycle has been assessed but also includes other papers which only integrated BIM to analyze carbon footprint, embodied carbon dioxide (CO2) or energy consumption.FindingsTaking into account the countries that have published articles about the subject, it is possible to deduce that it has been studied in all of the continents, except Africa. In comparison with other continents, Asia and Europe have developed more studies. Furthermore, 76% of the 34 selected articles were published in journals and only 24% in conferences proceedings, and the number of papers that relates life cycle assessment (LCA) methods using BIM has grown from 2013 to 2015, proving that the current theme is relevant. Several aspects of this literature review show the need to develop automated processes for LCA of buildings during the project's development phase. There is already a tendency to compare LCA results for buildings applied to BIM models, contributing to decision-making related to alternate projects, selection of materials, suppliers and components from an environmental perspective.Originality/valueIn the current global scenario, it is the notorious negative impact on the environment over the years caused by the architecture, engineering and construction industry (AEC). The integration of BIM–LCA can reduce time and improve the application of environmental analysis. Moreover, the proper application of a LCA method to evaluate the environmental impacts of the project can be hindered due to lack of information in the database about the materials or due to failures in the interoperability between BIM software and the LCA tool.

Abstract. From days to days, management of construction project has been improved during life-cycle project, starting from planning until maintenance. This happen cause of the advantages in implementation technology of Building Information Modeling (BIM) and Geographic Information System (GIS) in supporting construction project. Few years ago, enhancement in term of BIM and GIS that provides an additional extension for the purpose of information management is very interesting. With the advantages that been provided by BIM and GIS, information of construction project can be adapted into real situation of the construction site which be helpful during the life-cycle of building construction. BIM and GIS is a different platform which contains their own advantages that support construction project. In order to bring the most effectiveness in management of construction project, integration between BIM and GIS becomes an important task to support the design phase until operational phase which include the facility management and maintenance. Although this integration can support the building information management, the software that used in integration process is still having limitations and differences in fulfilling the needs of users. For that reasons, data consistency needs to be studied in order to develop the best practices of integration application. The purpose of this paper is to investigate the data consistency during the integration process. From the investigation, it showed that there are some data inconsistency occurs in IFC platform after conversion process. Through this paper, the comparison of the geometric and semantic data before and after translation process will be examined.

The paper considers application and development of information technologies while carrying out project management in construction. Organizational and technological support of works throughout its life cycle exerts an influence on quality and efficiency of successful implementation of the construction project. In order to achieve the project goal it is necessary perfectly to organize and plan works, distribute roles and responsibilities of the project participants, regulate composition and content of the project documentation. While analyzing technical and economic indices of construction organization activity and management systems operating in these organizations, conclusion has been made that market experience in functioning of operational management systems has not been adequately applied in practice of domestic construction organizations. Thus, introduction of integrated management systems for quality, costs, time parameters pertaining to project construction, their resource support will contribute to improvement of economic situation of construction organizations. The solution consists in application of up-to-date information technologies, maximum implementation of computer systems and programs in the sphere of production, creation of application software. It has been shown that it is necessary to develop a software model that provides a possibility comprehensively to apply information technology tools for monitoring progress of construction and installation works, systematization of information technology application that allow to control key parameters of construction and installation works, improvement of system for providing actual information in project implementation process. An example of complex application of software products Primavera P6 Professional R8.3.2 and ArchiCAD 17.0.0 is given in the paper.

The final year project (FYP) is considered a capstone course in information technology (IT) programmes and involves the development of a software product. Currently, students are using the traditional software development life cycle approach to manage their FYPs. However, this approach can cause many difficulties. This paper proposes an alternative software development model for managing the FYP in an IT and IT-related degree programmes of study. First, a benchmarking exercise was undertaken to compare the software developed for business purposes with that developed for educational purposes, which took into account the ten project management knowledge areas. The result of this exercise indicated that the differences that exist between business and educational software necessitate the development of a new software development model that is specifically tailored to the development of educational software. Therefore, capability maturity model integration (CMMI) was modified to generate a new version of CMMI – named educational CMMI – which could be used to evaluate educational software projects and detailed mathematical descriptions of the proposed model were composed. As conclusions, the proposed model was then assessed by students’ results and by questionnaire feedback, the results of which showed that the proposed model was both useful and applicable for its intended target users and context.

Software processes are usually described by guidelines and advices. These guidelines are claimed to be valid for many projects. This understanding leads to software processes which deviate from initial plans and which frequently yield insufficient results. System-atic management of software processes can help to overcome these shortcomings. In this paper, we introduce an incremental approach to software process management. This approach covers the complete life-cycle of software process models, i.e., it deals with software process modeling, software process model analysis, and software process model enaction. It is based on a net-based software process modeling language called FUNSOFT nets. FUNSOFT nets are high-level Petri nets adapted to the application domain of software process management. We model software processes by means of different views onto a software process model. Our approach is implemented in a software process management environment called MELMAC.

The problem of increasing the reliability and competitiveness of products in all sectors of the national economy can be solved only on the basis of obtaining complete and reliable measurement information. This is facilitated by modern measuring instruments (MI), which are complex hardware and software systems. The relevance of the study is due to the fact that modern MI need an effective assessment of their quality at all stages of the life cycle (LC). This requires the development of appropriate assessment methods both at the stage of production and operation of MI. The expediency of using the process approach to MI LC stages and its advantages over the functional approach were proved. The process approach allows more effective assessment of MI quality indicators at different LC stages and is compatible with the construction of modern quality management systems. Mathematical modeling was carried out, a set process model of the MI LC was developed and its representation as a process V-model was carried out. This allows studying the interaction of processes of all MI LC stages and performing process quality management at all MI LC stages. Mathematical modeling was carried out, a set process model of evaluation of quality indicators of MI LC stages was developed and its representation as a process V-model was carried out. This allows evaluating quality indicators of the MI and its components throughout the MI LC. Recommendations for the use of international standards were formulated, in particular for project management planning, measurement processes, system requirements throughout the MI LC, risk analysis and management at the LC stages. This should help increase efficiency in achieving the planned results at all stages of the MI LC

Introduction: when designing and constructing medical buildings, it is necessary to meet a large number of mandatory requirements established in the normative documents and by the customers. Medical buildings as social facilities should meet high requirements. By their complexity, they are close to industrial facilities. Therefore, there is a necessity to manage a system of such requirements during their construction.
Materials and methods: the definition of requirements is initially given for software development. A requirements management system (RMS) in construction is a part of the project management. It was suggested to use the RMS to improve the organization of medical building construction. Normative documents and the customer’s specification establish the baseline requirements.
Results: the article developed organizational and technological models of different life cycle stages of medical buildings. The models show the interaction of the state customer, technical customer, general designer, contractors, and suppliers of medical equipment. The models include business processes related to requirements management during design, construction, and maintenance. This system contains various requirements for the buildings, references to requirements sources, and results of verification and validation of the requirements. Verification should be carried out by a team of experts at the checkout points appointed by the project manager. At each checkout, the experts check the requirements and record the results in a database. The list of requirements that are not observed at the moment of the checkout is reported to the project manager. The paper provides an example of the RMS for nuclear medicine buildings.
Conclusions: for buildings of medical organizations provided with complex medical equipment, it is necessary to create an RMS for all stages of the life cycle. The developed system of establishment, verification, and implementation of the requirements can significantly improve the quality of design and construction activities, accelerate the process of commissioning, and provide the safety of the facility. Such a system is developed and used for nuclear medicine buildings. The application of it is possible for other medical centers.

In recent years, organizations have increasingly sourced cloud-based enterprise software (ES). Although comprehensively capturing organizations’ requirements considerably affects the success of an ES sourcing project, little is known about how requirements evolve beyond the implementation. We conduct a longitudinal, exploratory single-case study of the life cycle of cloud-based ES in a medium-sized organization. Over 5 years, we trace the evolution of requirements throughout the ES life cycle, beginning with the initial adoption decision and ending with considerations to retire the ES. We develop a process theory that explains how requirements evolve beyond ES implementation and throughout its life cycle. We isolate nine mechanisms that explain how contextual factors and experiences are intertwined and shape the evolution of requirements. We then develop seven propositions that explain how sourcing cloud-based ES alters the mechanisms that shape the evolution of requirements. Our findings emphasize that the evolution of requirements for cloud-based ES follows similar mechanisms to that of the requirements for on-premises ES but changes how particular mechanisms manifest. Sourcing cloud-based ES changes the influence of business divisions in acquisition and configuration activities, the role of upgrade and customization procedures, and the influence of the ES’ ecosystem.

This article presents a novel software tool for the assessments of life-cycle environmental impacts and costs, which is aimed to support decision-making in the design phase of retrofit interventions in the building sector. By combining Life Cycle Costing (LCC) and Life Cycle Assessment (LCA) calculations and functionalities, this tool allows evaluating the long-term trade-offs between economic and environmental performance of investment projects in energy efficiency for buildings, while accounting for uncertainties in input parameters and economic scenarios. A major novelty of the software tool is the stochastic nature of both the LCC and LCA dimensions. The LCA is implemented with Monte-Carlo methods, while the LCC accounts for the probabilistic interdependence of macroeconomic variables over time. The software also includes advanced specific tools for parametrization and sensitivity analysis. Exemplary applications are presented in order to illustrate the novelty and the functionalities of the software tool.

This study examines who are the social actors in coordinating the environmental hot spots along the process of desalination. The integrated model design of life cycle modeling and Social Network Analysis is evaluated holistically by the inventory of life cycle and actor engagement ratings. Instances of the first small-scale reverse osmosis desalination plant project in Kelantan, Malaysia were used to meet the demands of this study. Environmental performance is measured through the Eco-Indicator 99 method in the Life Cycle Assessment Principles. Meanwhile, the network analysis of the actors’ networks involves stakeholders visualized through the UCINET software. The results show three hotspot points of membrane and brine disposal, the use of electrical energy, and the use of chemicals. The results acknowledged that 87 percent of the actors’ involvement from the dominant stakeholder group has been in control of the management and of the aforementioned hotspot. Undoubtedly, the results of this study can provide a better understanding of the potential market of actors to work with a more accurate and polycentric information flow for the development of more established desalination systems.

Business process modeling was suggested by academia and implemented by the industry to trigger device requirements. Maturity models of software processes are also similar in the software industry. Therefore, business software requirement engineering approaches-based process should aim to fulfil with the maturity models. Although researchers in the area of Software Engineering, Project Management, and Business Intelligent have addressed planning and execution and a lot of research still needs to be done, in this study, we focused on doing a questionnaire based on different prominent universities, major companies, and software houses. The purpose of the questionnaire was to dig out the main factors that negatively affect software houses and their products and services, especially in the medical field. A questionnaire was generated to accomplish these reasons, and interviews were conducted to extract the key explanation why software developers and software houses in developing countries are not familiar with the CMMI (Capability Maturity Model Integration) model for medical software projects. This analysis attempted to figure out why the tech enterprises of developing countries are behind foreign competitors. We aimed to determine why software developers do not meet the international requirements for software. The novelty of the research is that attempts were made to strengthen the new approach by adding agile at level 3 to keep the local software industry appropriate and reveal the requirements for medical software life cycle study, because accurate decision support is really necessary for healthcare systems.

Full textAbstract:
The selection of cost-effective components of the building envelope plays a significant role in a sustainable building design solution. Therefore, in terms of effective decision-making, it is important to have a complete insight into construction and running costs throughout the lifespan of the building. A systematic building information modelling (BIM) approach as a new trend in the innovative approaches in the construction (AECO) industry provides appropriate support for improvement of environmental assessments. Our study presents a new approach to automated/semi-automated comprehensive energy and the whole life-cycle cost analysis of building envelope components using BIM, and, as such, it represents a novelty for Advanced Construction Project Management. It focuses on the sequence of steps required for evaluation of energy and economic assessment, from the basic 3D BIM model, through the energy and cost analysis, to the final evaluation and decision-making. The energy balance was calculated with dynamic simulation, the results of which formed the basis for the cost analysis. Economic assessment of construction and operating costs was performed by implementation of the cost-optimal methodology. Our proposed approach contributes to the environmental assessment of building envelope components throughout the life cycle and includes the economic valuation. The applicability of the systematic approach in our case study considered 24 different variants of building envelope components at three different U-values, namely U0 = 0.28 W/m2K for external wall, U0 = 0.20 W/m2K for roof, U1 = 0.15 W/m2K and U2 = 0.10 W/m2K. Sophisticated project BIM management software was used for the economic evaluation of all elements of the life-cycle costs (LCC). In summary, the main contribution of this approach is provision of a comprehensive and simple insight into all costs in a transparent way, because a 5D BIM model allows for optimal decision-making on appropriate energy and cost-efficient envelope components.

Accurate time and budget is an essential estimate for planning software projects correctly. Quite often, the software projects fall into unrealistic estimates and the core reason generally owes to problems with the requirement analysis. For investigating such problems, risk has to identified and assessed at the requirement engineering phase only so that defects do not seep down to other software development phases. This article proposes a multi-criteria risk assessment model to compute risk at a requirement level by computing cumulative risk score based on a weighted score assigned to each criterion. The result of comparison with other approaches and experimentation shows that using this model it is possible to predict the risk at the early phase of software development life cycle with high accuracy.

In the construction industry there is a necessity for improving the construction efficiency through adopting innovative methods. Information and Communication Technologies (ICT) help in increasing the client satisfaction reduce coordination errors and provide a greater understanding among project participants in terms of better handling issues and requirements. Better efficiency can be achieved by making a building smarter. Construction projects are faced with many challenges that must not be ignored or underestimated. Some of the wicked problems and challenges such as understanding how one decision will impact decisions in other areas; problem of addressing the risk due to dynamic and uncertainty existing in the environment; resolving conflict where there are competing claims resulting both good and bad outcomes from the same value system are required to be well managed, if required using innovative methods such as using ICT and software packages. Therefore Objective of this research is to explore and describe the use and applications of information and communication technologies in construction industry. It involves examining the current trends of ICT based construction practices and also to assess the potential for its improvement by way of innovation. In this the journey started with describing what innovative methodologies are required to be considered to drive the discussion of adopting and using ICT to handle the wicked problems in construction industry. Two rationalities are considered as a basis for working on ICT applications in construction management viz.: (i) Six stages of Project Life cycle management and (ii) Nine project management knowledge areas as described by PMI.

Software Engineering is a branch of Computer Science that evolved as a result of urgent need to deal with decades of software crisis, characterized by low theoretical knowledge and practice of the construction of error-free and efficient software. The introduction of well-organized scientific, engineering and management strategies in the process of software development no doubt led to major breakthroughs, and solutions to software failures. One of the obvious game-changer in this regard is the evolution of Software Development Life Cycle, also known as Software Process Model for driving the different phases of software construction. A sound understanding of the process model is therefore inevitable, not just for software developers, but also to users and researchers. Such a theoretical cum practical understanding will enhance decisions on which process model is best for a particular job or perspective. This invariably, contributes immensely to the probability of success or failure of the project in question. Thus, the necessity for this research. This work presents an unambiguous expository of selected software development model variants. A total of four process model variants were studied, in a theoretical, visual and analytical manner. The variants were analyzed using strength versus weakness (SVW) tabular scenario. This work was concluded by presenting guides towards choice of these models.

Full textAbstract:
Military government was lifted from Kinmen in 1992. The opening-up of cross-strait relations transformed the island into a tourist destination. This transformation led to electricity and water shortages in Kinmen. With the reduction in the number of troops, military facilities fell into disuse and are now being released for local government use. The aim of this project was to monitor the carbon footprint of a reused military facility during renovation of the facility. The LCBA-Neuma system, a local carbon survey software developed by the Low Carbon Building Alliance (LCBA) and National Cheng Kung University in Taiwan, was used in this project. The system analyzes the carbon footprint of the various phases of the building life cycle (LC) during renovation and carbon compensation strategies were employed to achieve the low carbon target. This project has pioneered the transformation of a disused military facility using this approach. The carbon footprint of energy uses during post-construction operation (CFeu) accounted for the majority of carbon emissions among all stages, at 1,088,632.19 kgCO2e/60y, while the carbon footprint of the new building materials (CFm) was the second highest, at 214,983.66 kgCO2e/60y. Installation of a solar cell system of 25.2 kWp on the rooftop as a carbon offset measure compensated for an estimated 66.1% of the total life-cycle carbon emissions. The findings of this study show that the process of reusing old military facilities can achieve the ultimate goal of zero carbon construction and sustainable development.

"Application of a life cycle assessment for assessing municipal solid waste management systems in Bolivia in an international cooperative framework." Waste Management & Research 38, no. 1_suppl (March 5, 2020): 98–116. http://dx.doi.org/10.1177/0734242x20906250.
Full textAbstract:
Using a life cycle assessment (LCA) to evaluate municipal solid waste management (MSWM) systems is strongly recommended and the approach has been used in high-income contexts. However, stakeholders in low to middle income countries are not aware of the potential of this approach, mainly due to a lack of financial resources and technical ability. The present work introduces a LCA of MSWM system scenarios into a developing city using an academic licence for the LCA software that is available for use exclusively by researchers. The MSWM system in place in 2018 in La Paz (Bolivia) was assessed according to seven scenarios. The novelty of the research is twofold: the use of LCA academic licensing in a low to middle income region where LCA is unknown as planning tool; and discussing the potential of the approach in conjunction with local and international stakeholders with a view to starting MSWM projects. The results of the analysis allow for the consideration of energy recovery and materials recycling as the main methods by which the environmental impact of MSW can be reduced, as has also been reported by other LCA studies conducted with full licensing of the relevant software. Moreover, the research is the basis for cooperative development projects that will adopt the LCA approach as the main assessment tool. The study discusses the importance of cooperation between universities and local governments for implementing new strategies for MSWM assessment and planning. The research is a contribution towards improving technical knowledge in developing countries for boosting sustainable development.

Built Environment Project and Asset Management 7, no. 3 (July 13, 2017): 313–29. http://dx.doi.org/10.1108/bepam-08-2016-0037.
Full textAbstract:
Purpose A case is made for developing “Relationally Integrated Value Networks for Total Facilities Management” (RIVANS-TFM) by synergistically connecting significant stakeholders of the project management (PM) and facilities management (FM) phases to deliver substantially better value for the end users of built infrastructure. The paper aims to discuss these issues. Design/methodology/approach A structured questionnaire survey enabled identification of typically significant stakeholders in the PM and FM phases. In total, 14 key stakeholders were identified through t-test analysis in this Sri Lankan study. Semi-structured interviews unveiled relationships among the aforementioned stakeholders and the findings were used to develop the “required” RIVANS-TFM, as well as the “existing” RIVANS-TFM, using the UCINET social network analysis software package. Social network theory of relationships was applied to analyze the networks in terms of “Structural Holes” or missing links and “Brokerage Potentials.” Findings Structural holes analysis highlighted the existing setup to be more vulnerable to missing links than the “required”/targeted setup. Furthermore, brokerage potentials analysis revealed that owners, project managers, facility managers, maintenance engineers, main contractors, designers, principal consultants, and other specialist consultants can act as “brokers” to bridge the gaps or minimize structural holes, thereby uplifting and reinforcing the existing network to deliver better performance and value in TFM. Originality/value By revealing existing and required levels of integration of each stakeholder in RIVANS-TFM, clients are provided a great opportunity to identify the stakeholders who should be engaged more, or less – in order to best achieve clients’ long-term aspirations and project objectives. Furthermore, the findings also indicate appropriate levels of stakeholder relationships to target, in order to maintain efficient flows of information, material and services in the supply chains while enhancing TFM life-cycle values.

Full textAbstract:
This note focuses on the development and production phases of the oil & gas upstream cycle. The first one includes all activities and processes required to optimally develop a field. The second one is related to all activities performed to extract hydrocarbons from a reservoir and their treating at surface. The development phase is very complex and plays a very important role in a company’s strategy. In order to govern the process in each step and to obtain the best results in terms of profitability, risk reduction and safety, the oil companies have defined precise guidelines and try to adopt the most innovative technological solutions in the performed studies. According to these guidelines each project is based on a phase/gate approach and each phase has a set of clear objectives that, once achieved, allow the project to proceed into the next phase. During the development phase a set of studies are executed to ensure that asset development and project execution will be done at the best minimizing uncertainties and associated risks. The activity of reservoir characterization is the most important of these studies as its results have a strong impact on the final decisions. The objective of a reservoir evaluation study is the construction of a 3D model of the reservoir through a multi-step process that uses dedicated software. The purposes of this activity include improving the estimation of oil in place and reserves, predict future production, evaluating different development scenarios. While the development phase is optimized to be as short as possible, the production phase can last several years depending on the size of the field and the costs the company has to bear to maintain the system working. During its production life the field is continuously monitored through an activity called Reservoir Management. The objectives of the Reservoir Management activity include the continuous update and validation of the reservoir dynamic model and the definition and assessment of the technical and economical feasibility of well interventions aimed at field production optimization. Many studies in this phase are focused on the selection of the best oil recovery technique. Among them Enhanced Oil Recovery (EOR) techniques, although more expensive, are gaining high popularity as they provide a way to recycling CO2 created by industrial processes. The last part of this note is dedicated to an overview of what the oil companies and Eni in particular are doing or planning in order to meet the targets defined in the Paris agreements in terms of reduction of greenhouse gases emissions while still satisfying the world’s energy needs. Since renewables still have economic and technological limits when deployed on a large scale, Eni is promoting gas as an ideal partner for the development of renewables and is increasing the share of natural gas in its portfolio. The use of the gas-renewables mix also enables coal consumption to be reduced. New technologies are expected to play a key role on this journey towards a more sustainable model thus Eni is continuously increasing its budget in research and development projects for carbon neutrality.
