The aim of the thesis is improvement of the recruitment process for the position of welder in a particular company so that the plan to hire 45 new welders would be filled until the end of 2015. As part of the process another opportunity to improve was found and defined. This secondary issue is high fluctuation of welders. Secondary targets of the thesis include mapping, measuring and analysis of the current state of new workers recruitment and also positive motivation of current welders, which create the basis for proposed changes that were later implemented. In the last step the impacts of these changes are controlled and summed up. The whole process follows the DMAIC method steps. During the real project solution tools like Lean management, SIPOC, Flowchart and Ishikawa diagram, first pass yield, A3 report and Benchmarking were used. Above mentioned methodological tools are all described in the practical part of the thesis. In conclusion, it was found out that suggested and implemented amendments improved the recruitment process by 12 percentage points. Fluctuation, the second drawback, is however not possible to measure yet as the impact of the changes will be expected to show within 1 year. Although there was a significant improvement of the whole processes, the plan was not met up to the last day in October 2015. Out of the 45 planned positions, 37 welders in total were casted.
