Hello Eric
You are right that statistics indicates your current performance and your improved performance. To emphasize when we say that we talk about ‘improvement’
it is a result of some modification in the process. If the output of the process has changed positively we say we have attacked ‘right cause of variation’.
Coming to your situation, could you answer my following questions,
Have you defined the objective of the project?If so, you are looking forward to achieve change in which parameter?With the change that you expect in outcome of the project, what cost savings you expect?
ABOVE QUESTIONS RELATE TO THE SCOPE OF THE PROJECT?
Have you identified the potential area for cost saving?If so with the application of breakthrough strategy what improvement you have achieved?Have you converted the improvement into money language?If so has the outcome met the target you defined in the scope?
ABOVE QUESTIONS RELATE TO THE EXECUTION OF THE PROJECT?
It is the scope that defines a Project as simple or complex. In my opinion we cannot define anything such too simple for a six sigma project or anything of that kind. If you have defined a scope and achieved the scope using six sigma methodology, it can be called as a successful six sigma project.
However I require more specific information about your situation so that I can suggest some solutions in the related areas.
I can provide you with case studies in my experience but they are too big to dicuss here.
