Fredriksons Verkstads AB senses a tougher competition, not only by themselves but also among their customers, which is one reason to this study. In addition to the in-creasing competition customers understand the market better, which increases their demands. This report is an effect of such development, because the case company Fredriksons Verkstads AB, does strive for organizational development and to meet customers’ demands. The purpose of this study is to define the capability of a laser cutting process. The study investigates both the machine capability and if the opera-tors have any effect on the process. Parallel to the capability study, Fredriksons Verk-stads AB own routine for capability analysis was reviewed.With the aim to determine the capability, the theory of Six Sigma was practiced. This study was based on the systematic project steps of the DMAIC-cycle. With this approach it was possible to determine that two of the laser cutting machines did not perform well enough. One machine was shown to be off target regard to the expectation of the machine distributor performance promises of the machine. Further on in the analysis it was shown the operators did not influence on the process, at least no significant influence.This study included an analysis of the tools for measurement and thereby an investigation of the reliability. Based on this analysis it was possible to say that the data was measured correctly.Fredriksons Verkstads AB routine for capability test was revised. The analysis showed that the previous routine was hard to understand and to use.This study resulted in one calibrated laser cutting machine. The measurement analysis pointed out differences between the tools, which was helpful when deciding the most appropriate way to measure, depending on the specific situation. A new guideline was developed to give better support for new Six Sigma projects at Fredriksons Verkstads AB. / <p>Validerat; 20150829 (global_studentproject_submitter)</p>
