RE: Six Sigma Principles
It is far easier to implement Six Sigma principles in a product manufacturing facility because the statistical nature of its process control lends itself more readily to the quality improvement of 'widgets' than it does software. The primary reasons that the principles of Six Sigma do not lend themselves to sustained improvements in the software industry are:

1) Process variation can never be eliminated or even reduced below a moderate level because no two modules are alike. Consequently in software applications process performance always include a high degree of variability.

2) Specifications are not based on tolerances. In software systems don't fail because they are assembled from components that do not meet tolerances. Instead a single well-placed defect can bring down a software application.

I am not saying Six Sigma can't be successfully applied to the software development
process but a great deal more imagination and thinking must be devoted to its processes in order to achieve continuous and sustained process improvements in software development.
