Mark Donovan presented on John Shook's Lean Transformation Model and discussed potential triggers for Lean transformation. He questioned why some commit fully to Lean after just one book or meeting when they have not directly experienced the benefits themselves. Donovan suggested a change in perspective may be the "seed of transformation" and that experiments are needed to test potential Lean triggers like trust, intention, mindset, and assumptions. He asked if Lean is being pushed from upstream or if pulling Lean from customers instead could lead to different outcomes.
