Motion is a waste in Lean projects and is the correct answer. Motion is when items are moved from person to person; this takes time and creates waste. Waste occurs when there is not a clear workflow of how items move through the project
processes. WIP (work in progress) is needed in Lean and is not waste. Even though bottlenecks are wasteful, the identification of bottlenecks is not waste. Colocation is a desirable element for the project team.
