Process improvement and Six Sigma embrace many principles, the most important of which in our opinion are discussed in this section. When understood, these principles may cause a transformation in how you view life in general and work in particular
The principles are as follows:
Principle 1— Life is a process (a process orientation).
Principle 2— All processes exhibit variation.
Principle 3— Two causes of variation exist in all processes.
Principle 4— Life in stable and unstable processes is different.
Principle 5— Continuous improvement is always economical, absent capital investment.
Principle 6— Many processes exhibit waste.
Principle 7— Effective communication requires operational definitions.
Principle 8— Expansion of knowledge requires theory.
Principle 9— Planning requires stability. Plans are built on assumptions.
