Here's my shortest-so-far adoption guide:
Change your viewpoint (lean flow paradigm):
See work as flowChange your mindset (foundational principles):
Start from here and improveChange your process continually (core practices):
Make work and policies visible; make validated improvements Sound simple? Maybe, but it's the starting point for a journey with no final destination - no process-nirvana of global optima. Improvement, like change, is here to stay.
Note: for tweeting purposes here's the even shorter version: see flow; start here; with visible work & policies, validate improvements.
