Engineers default to optimizing bad steps instead of removing them. A step that takes 3 minutes can be optimized to 2 minutes — or eliminated entirely. This worksheet forces the hard question: "Does this step need to exist at all?" Toyota's principle is clear: the best process is the shortest process. Every step you eliminate is a step that can never break, never slow down, and never need resources again.
Challenge everything. When someone says 'we've always done it this way,' that's your biggest elimination opportunity. The most dangerous waste is the waste nobody questions because it looks like real work.
