Six Sigma in SMES with low production volumes: a successful experience in aeronautics

Abstract

Six Sigma is currently one of the most powerful tools that exists for quality improvement. Designed for highly repetitive and high volume production manufacturing processes, it has been adopted by leading large organisations in many different sectors all around the world. Our goal is to study its applicability to SMEs with low production volumes and identify key success factors and obstacles to its implementation. The methodology followed is Action Research in an SME in the aeronautics sector using the DMAIC improvement cycle applied to a specific Six Sigma project. The results confirm Six Sigma’s applicability and suggest that success depends on key factors, such as the team’s commitment, the availability of resources and prior learning.
