Process improvement can often be received with impatience and inflated expectations of its impact. One of the regular problems is that a particular piece of the organizations process is asked to be improved in isolation. This is a little like trying to change a wheel while the car speeds along the interstate! The one minor fix is still influenced by the wider system. It can take several improvements to elements of a process to see an impact overall. It needs to be realized that an entire process needs to be improved not just one element in isolation. That’s why they refer to Quality and Process Improvement as being about ‘systems’.
