When they set out to turn around processes that have become woefully inefficient or ineffective, most companies choose one of four process improvement “religions”: Lean, Six Sigma, Business Reengineering or Business Process Management (BPM). After hearing about its success at another organization, many companies choose just one. For example, several companies embarked on Six Sigma programs after their CEO heard about GE’s success with the approach, and many other companies have adopted Lean because of Toyota’s success. It’s like adopting a diet or exercise program that a friend has used and lost 50 pounds.
But some companies realize they need to go beyond making episodic improvements. They try to institutionalize process improvement — that is, put in place the right mechanisms in their management systems so that their business processes don’t become grossly unproductive in the future. That is, they try to build continuous improvement into their DNA. It’s like the difference between going on crash diets every two years and fundamentally changing one’s eating and exercise habits.
