Here's my shortest-so-far adoption guide:
- Change your viewpoint (lean flow paradigm):
See work as flow
- Change your mindset (foundational principles):
Start from here and improve
- Change your process continually (core practices):
Make work and policies visible; make validated improvements
Note: for tweeting purposes here's the even shorter version: see flow; start here; with visible work & policies, validate improvements.
