I'm assembling a team to tackle a setup time reduction project, and I wanted opinions on how big it should be. So far it's myself and 3 floor supervisors, but we need operators as well. We have 4 shifts. Does it make sense to take one from each shift so we have an 'ambassador' from each one to get buy in? Do I take the best 2? I don't want an overly large group, could become unwieldy.
