Full textInformation technology (IT) is a component that influences organizations´s performance and its effective application constitutes a challenge due to the speed associated to technological changes and the amount of financial resources and expertise of human resources required for its implementation. One of the strategies adopted by organizations to meet the needs of IT is to outsource all or part of the provision of IT services. The objective of this study was to describe the essence of the meaning of advisory experience according to the perception of professionals who provide IT consulting services. To achieve this purpose, a phenomenographic research was conducted in order to allow a group of fifteen consultants working in a regulatory public institution freely put its experience on the provision of IT consulting services. The data analysis resulted in the identification of the themes Acting Area Significance, Competency Advisory Conformation, Services Valuation and Advisory Predisposition related to IT consulting. The meanings attributed for these subjects allowed to propose a description of the essence of this kind of experience. The relevance of the research lies in the fact that, typically, the outsourcing analysis emphasizes the outsourcing contractual relationship established between the contractor and the contracted company and recognizes the consultant as only one of the resources needed to provide the service without considering the peculiarities inherent to the advisory activity.
McElhiney, Patrick R. "Scalable Web Service Development with Amazon Web Services." Thesis, University of New Hampshire, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10931435.
Full textThe objective of this thesis was to explore the topic of scalable web development, and it answered the question, “How do you scale a website to handle more traffic at peak times without wasting resources?” This is important research to any web company that has issues with rising costs as demand for their website increases. It would be wise for every online business to be prepared for more web traffic, before it occurs, without spending the budget of a multi-million user web company in low traffic periods. The last thing you want is an error as your customer base starts to arrive, giving them a bad experience for their first impressions, which would result in lost revenue.
Scalable software development architectures, including microservices, big data, and Kubernetes were studied, in addition to similar web service companies including Facebook, Twitter, and Match.com. A scalable architecture was designed for a social media web service, MeAndYou, using the big data configuration with a shared Aurora database, which was configured using an auto-scaling group attached to a load balancer in Amazon Web Services (AWS). It was tested using a custom threaded Selenium-based Python script that applied simulated user load to the servers. As the load was applied, AWS added more Elastic Compute Cloud (EC2) instances running a virtual disk image of the web server. After the load was removed, the instances were terminated automatically by AWS to save costs.
Countless steps were taken to make the web service bigger and more scalable than it originally was, before testing, including adding more fields to user profiles, adding more search types, and separating the layers of code into different Hypertext Preprocessor (PHP) files in the front-end. A version control system was configured on the servers using GitHub and rsync. The systems architecture designed suggests the Match Engine should use a stream processing message queue, which would allow the system to factor searches one at a time as they are created, with horizontal scaling capabilities, rather than grabbing the entire database and storing it in memory. The backend Match Engine was also tested for accuracy using Structured Query Language (SQL) injection, which determined how the match algorithm should be improved in the future.

Full textOptimized quality of IT services are those which need pre-analysis of users’ requirements, service provider’s capabilities as well as service specification and standardization. For any organization, maintaining of quality of IT service has become one of the key challenges which holds a significance importance to users’ satisfaction. Thus, this research tries to explore and identify the key factors of service quality dimensions and its affect on Information Technology Service so that organization can understand and follow the possible way to maintain quality of IT service to satisfy its end users. To achieve ultimate target of this research, the relevant three literatures have been reviewed and then the concept structure has been proposed for the analysis. From the respective three literatures, service quality dimensions have been selected to be tested for quality practices in Information Technology Service Department in the United Nations Office on Drugs and Crimes (UNODC).A qualitative research approach has been used to get a better understanding of the issue. The empirical data has been gathered through the study of internal documents, five days of participant observations and in-depth structured interviews with three quality assurance staffs and one IT service user from UNODC. Data presentation and analysis have been done in accordance with the literatures framework and research questions. Finally, conclusion has been drawn by answering research questions based on the issues identified. The findings of the exploratory case study suggest that considering of dependability, prior requirement analysis, and functionality of IT product and services could be taken up to bring realistic, clear, and goal-oriented quality approach in the Information Technology Service which address users’ expectations. The quality dimensions and the gap identified in the research study provide an avenue to address the quality related difficulties that IT service organizations encounter while developing of IT services. This study is expected to create a significant contribution to the areas within a domain of service quality in Information Technology as well as in Information System and Information Management.

Drivers using information from an Advanced Traveler Information System (ATIS) could potentially make better travel decisions to reduce travel time and increase trip reliability, thereby benefiting both guided drivers as well as those without such access. However, market penetration of ATIS can have dramatic effects on the performance of the transportation system in terms of overall benefits conferred as well as the distributional effects between guided and unguided drivers. Because market penetration will be determined both by private market structure and public policies, the effective deployment of ATIS depends critically on the private and public organizations that will provide these services. An understanding of the relationship between transportation system performance and ATIS market penetration provides important insights into a sustaining market structure for the ATIS industry. This thesis provides an empirical study of the impact of ATIS on transportation network quality of service using an application of DynaMIT (Dynamic network assignment for the Management of Information to Travelers). An analysis of the simulation results serves to inform the public and private stakeholder positions in the creation of a better market for ATIS. The main results are that the provision of dynamic route guidance can simultaneously benefit the individual performance of drivers, both guided and unguided, as well as the system performance of existing transportation infrastructure. In order to perform this analysis, it was necessary to develop a new software framework for the real- time integration of DynaMIT and a Traffic Management Center (TMC).

Full textContext information är information som beskriver användarens omgivning. Adaptive Context Aware Services (ACAS) projektet har som mål att möjliggöra applikationer att använda kontext information för att anpassa sitt beteende till användaren och dess miljö, utan att kräva att användaren ska sätta eller hantera alla parametrar manuellt. ACAS projektet har tidigare infört konceptet "context network" som förbinder context aware enheter. Det finns dock kvar några obesvarade frågor angående upptäckt av context information och av context aware enheter.Trots att sättet att länka ihop kontextmedvetna enheter för att forma ett logiskt 'kontext nätverk' introducerades tidigare i projektet, finns det kvar några obesvarade frågor angående upptäckt av kontext information och upptäckt av kontextmedvetna enheter. Examensarbetets mål är att utforma och utvärdera ett sådant kontextnätverk som ger enheterna möjlighet att upptäcka varandra och utbyta information om tjänster och context information. Därför utvecklades "Context Entity Registrar" så att enheterna kan registrera sig för att kunna bli upptäckta av andra enheter som kan göra förfrågningar till detta register. Under designen av denna föreslagna lösning har särskild fokus lagts på registrens prestanda, speciellt avseende skalbarhet med avseende på antalet förfrågningar for att validera designens potential som lösning för kontextmedveten upptäckt av enheter. Mätningar har visat att lösningen skalar bra vilket gör kontext registret till ett nyckelelement i ett kontextnätverk. Upptäkten av andra enheter och av kontextinformation har en viktig roll i att bestämma en kontextmedveten implementations prestanda. Detta examensarbete kommer först att behandla kontextnätverkets arkitektur och därefter några testerna för att mäta prestanda i den föreslagna lösningen.
Ojo, Michael O. "Big data analytics solutions| The implementation challenges in the financial services industry." Thesis, Robert Morris University, 2016. http://pqdtopen.proquest.com/#viewpdf?dispub=10111816.
Full textThe challenges of Big Data (BD) and Big Data Analytics (BDA) have attracted disproportionately less attention than the overwhelmingly espoused benefits and game-changing promises. While many studies have examined BD challenges across multiple industry verticals, very few have focused on the challenges of implementing BDA solutions. Fewer of these studies have focused directly on the financial services industry, and none have quantifiably measured the severities of the challenges. That created gaps as BDA solution implementers in the financial services industry could neither access a roadmap to guide their steps against obstacles that lay ahead, nor compute the severities of the challenges. This study addressed those gaps through two research questions: (1) What are the challenges of implementing BDA solutions in the financial services industry; and (2) What are the rankings of these challenges, in terms of importance and relative severities, such that BDA implementations can devote more research attention to or hedge better against those challenges? To answer these questions, the study used a mixed methods approach to content-analyze 75 BDA documents and collate a comprehensive list of 22 BDA challenges. As well, 36 financial services industry BDA-subject-matter-experts (SMEs) were surveyed to validate the list, rank the challenges, and measure their impacts. The research findings showed that the challenges of implementing BDA solutions in the financial services industry are mostly strategic and people-driven, rather than process-induced or technology-driven. Specifically, miscommunications and misconception of the meanings, intents, and the value-added benefits of BDA implementation in the financial services industry were found to be the top challenge. Details of the results, its implications for the BDA communities of practice and discourse, and opportunities for future research were discussed. The results can be generalized if scaled with a bigger sample size and better measures-of-intangibles.

Full textFor now, vastly growing Web-technology has matured enough to become an attractiveplatform for business applications and organizational information systems. Indeed, largeand small organizations are increasing their investment in Web-based Information Systems(IS) resources, such as Electronic Commerce, Intranets and Extranets. As DIWA(1999) explained that Web technology is often presented as a 'revolution' in informationsystem technologies in the business press, which could propel change from static, hierarchicalstructures to more dynamic, flexible and 'knowledge-based' organizationalforms. To the companies, more and more legacy information and database systems arebeing migrated to Web-based environments.
This research aims to analyse and advise enterprises to be Web-based enterprise withchallenges and opportunities.
During the research, the author investigated a company that were using the Web-based(applications made available via the World Wide Web) information service. For obtainingreliable conclusions and delivering valuable advises, various research methods wereadopted by the author including qualitative research methodology, analysis, interviews,and literature study. Data was collected through lecture review and in-depth interviews.
Undoubtedly, there are some troubles existed in migrating, such as technologies for restructureinformation system structure, resource distribution, benefit analysis, planningand management, operation and maintenance etc.
But still obviously, as the research shows that there are many benefits can be got followsthe implementation of Web-based solution, which includes improving efficiency,modernizing company IT environment, providing better IS/IT systems’ maintenanceand providing more agility and functionality etc.

Full textZimbabwe has a fairly developed health-care delivery system that is served by public and private hospitals at district, provincial and national level. The public health-care system is the largest provider of health-care services and caters for the majority of the population but this is done in a resource-restricted context, typical of a developing context. In this context, this research sought to establish the potential of mHealth Technologies in Zimbabwe’s maternal health sector using Parirenyatwa and Harare hospitals as case studies. The reviewed body of knowledge, which was largely a comparative assessment of mHealth technology adoption in developing countries, indicated that the full adoption of the prevailing eHealth strategy in Zimbabwe remains hamstrung by the slow pace of policy implementation. This is a qualitative study and data was collected with unstructured interviews. Purposive and snowball sampling were used to recruit the participants. The gathered data was analyzed through content and thematic analysis. Four broad themes emerged from the primary data collected during the interviews and these include: trends in information dissemination in Zimbabwe’s Public Health System; information needs for expectant women and midwives; the prevalence of ICT use in Zimbabwe’s Public Health System, and mobile technology use in the maternal health sector in Zimbabwe. The research was able to establish that while there is a high proliferation of smartphone use among most expectant women, this has not translated into their use for health information-related purposes.
Pelletier, Justin M. "Effects of Data Breaches on Sector-Wide Systematic Risk in Financial, Technology, Healthcare and Services Sectors." Thesis, Capella University, 2017. http://pqdtopen.proquest.com/#viewpdf?dispub=10615009.
Full textThis research informs an ongoing debate regarding a firm’s incentives to invest in information security. Previous research reported that data breaches have had a decreasing impact on a company’s stock price over time, leading researchers to conclude that market-based incentives are decreasingly effective. Some information security economists also suggested that further regulation is necessary because they found that capital market participants poorly accounted for the spillover effects of a breach—the effects of a breach that are external to the breached company. However, some studies indicate that sector-wide systematic risk could measure spillover effects and that the effects of a data breach on systematic risk may have changed over time. The purpose of this study was to quantitatively describe the relationship between the data breach of a firm and changes to the systematic risk of that firm’s sector. This dissertation used event studies of sector-wide systematic risk within American stock markets to measure the external effects of breaches that occurred in companies within the financial, technology, healthcare and services sectors. The use of a repeated measures analysis of variance between those event studies allowed examination of longitudinal changes to sector-wide systematic risk between 2006 through 2016. This analysis found that the breach of an individual company had a significant impact on the systematic risk for that company’s entire sector (1.08% in 2016) and that these impacts have increased over time (p = 0.015). The results were consistent across all measured sectors, without any significant correlation attributable to the scope of the breach. Together, these findings suggest that market forces are increasingly incentivizing sector-wide investment in information security. Further research should consider the potential for government enforced meta-regulation of sector defined information security standards.

Full textUnderstanding the use of information and communication technology (ICT) in the Namibian's health sector is important in the global information society It is not clear how ICT is being deployed to support the delivery of health services to the Namibian patients. Health service providers (HSP) in both private and pUblic health sector must be aware of ICT use patterns because this may influence how they deliver services to their patients in the future. This study thus seeks to investigate how ICT have been used in the delivery of health services to patients in the Khomas and Oshana regions of Namibia. Based on the literature review and data collected from the HSP and patients, a 'generic' health service delivery landscape for Namibia was developed and regional landscapes for the Khomas and Oshana regions were further derived from it. The landscapes depicted health service provision to patients in the different health sectors in Namibia. After mapping the health landscapes primary data was collected from the health service providers (HSP) in private, mission and public health institutions using a questionnaire A second structured questionnaire was administered on the patients A total of 21 and 134 HSP patients respectively, responded to the survey questionnaire. Results from the descriptive analysis indicate a relatively high ICT use by both HSP and patients.

The innovative firm must continually evaluate its boundaries - decisions often shaped through make-buy-partner evaluations and choices about where to define the firm's competences. Building off of earlier work that suggests heterogeneity in types of organizational competences, I submit that a firm's portfolio of organizational capabilities map across three states: core, supplementary, and complementary. Core capabilities are the defining competences that are imprinted during the founding and formative years of the firm. Persistence in the core often leads to inaction and failure. Supplementary capabilities may form after the firm establishes its core and whose origins are traced to diversification expansion events. Complementary capabilities may form at founding and/or as managers detect competence gaps during changing conditions. Complementary is activated primarily to increase the value of the core. Given the firm as a portfolio of heterogeneous competences, the dissertation's focus is on when, why, and how the established innovator activates new complementary capabilities in dynamic environments. The context is hardware product vendors within the Information Technology (IT) industry and the complementary organizational capability is the business of professional services - e.g., consulting, systems integration, and custom implementation. Considering the expansion into professional services as a type of related diversification, the first paper uses panel data of U.S.-based IT product firms from 1987-2008 to explore the industry-level patterns behind the expansion into complementary services-centric domains given the core expertise in R&D-centric activities. I find that product firms who were diversified into more complementary R&D-centric activities (e.g., software) were more likely to diversify into complementary professional services - suggesting that professional services are part of a larger architectural/portfolio enablement strategy. The next part of the dissertation explores this phenomenon further by examining the process by which two innovative firms activate new complementary capabilities using polar-opposite dominant models: EMC preferred to "make" while Cisco preferred to "partner." Both case studies emphasize the process and unique dilemmas with the activation and evolution of complementary capabilities from 1995-2010, an era marked by continuous technological change and market uncertainties. I conclude with a discussion of the common patterns across these two firms and managerial implications.
