Abstract

Many companies around the world have implemented Six Sigma as a problem solving methodology especially useful for dealing with recurring problems in business processes. Since the 1980s when it was developed at Motorola, many companies have tried to implement Six Sigma to fit their own company’s culture and goals. This thesis presents a longitudinal case study describing the evolution of ‘Six Sigma Management’ at Siemens in Sweden. The success of the programme was to a large degree built on previous failures, confirming Juran’s old saying ‘Failure is a gold mine’. From the case study, success factors for implementing Six Sigma at Siemens are identified and compared to those given in the literature. Some of the most critical success factors identified at Siemens had not been mentioned as such in the literature before. The main conclusion of the study is that, in order to succeed and get sustainable results from a Six Sigma programme, Six Sigma should be integrated with Process Management, instead of just running Six Sigma as a separate initiative in an organisation.
