Is there any guideline to know what tool to use (Fishbone, Pareto, CTQ, etc) during the measurement phase to focus in a specific area or are the more tools you use the better?
Good question. There’s actually a great companion piece to the Green Belt Training called the DMAIC Field Guide – this lists challenges, best practices, deliverables and suggested templates/tools for each Phase.
