ABSTRACT
A toll gate is a list of questions that need to be answered before moving to the next phase. Think of the toll gate as a checklist to ensure everything has been completed. In straight Six Sigma, it is rare to start activities on a phase until the previous phase is complete. Lean Six Sigma is a little more flexible. In other words, if there is an opportunity in Define to satisfy some of the Measure requirements, those are taken into consideration. Remember that Lean Six Sigma is about speed and efficiency, as well as getting good solid data.
