Simply stated, the deployment of Six Sigma in a single functional area (to the permanent exclusion of others) will most likely not succeed.  Generally speaking, Six Sigma is an “all or nothing” proposition.  However, if the overall deployment and implementation plan (for the total organization) calls for a staggered but comprehensive rollout over time, then such a “targeted” approach will likely succeed.

Although this type of approach is highly recommended, you are well advised to “preordain success” for the first attempted installation.  In other words, if the first implementation of Six Sigma fails, the overall deployment will be in considerable jeopardy.  If this happens, a “restart” of Six Sigma is next to impossible.  Therefore, do it right the first time.  This point cannot be overemphasized.
