Process Reengineering, as popularized by Michael Hammer in the mid ’90s, involved “blowing processes up” and starting with a “blank sheet of paper.” Although Hammer reconsidered this approach in later books, the idea was to ignore the current process and just design a new one. Process Improvement projects involve analyzing the “as is” process to build profound knowledge about a process, pinpoint existing waste and then use that knowledge to make key changes to the process. Both approaches have the goal of a desired future state, but process improvement achieves it by studying the current state. It’s much cheaper to conduct process improvement!
