How does Six Sigma compare with other improvement initiatives?
Resolve to perform what you ought; perform without fail what you resolve
Overview A number of improvement initiatives are, or have been at some time, in common currency. These are described at the appreciation level and compared with the Six Sigma process. It will be noted that Six Sigma adopts, and builds upon, many of the best-practice methods and practices applied in other initiatives. It is unique, however, in respect of its enabling and perpetuating infrastructure of ‘Judo’ belts. It also aims to combine and refocus a whole range of improvement tools that, hitherto, have been largely deployed in a fragmented manner. This fragmentation of deployment of various tools and techniques in a number of organizations is illustrated in Figure 3.1. Such organizations do not deploy these very useful methods in a cohesive manner.
