“What should I work on next?”
Yuval Yeret quotes David Anderson:
- Value trumps Flow – Expedite at the expense of flow to maximize value
- Flow trumps Waste Elimination – Increase WIP (work in progress) if required to maintain flow even though it will add waste
- Eliminate waste to improve efficiency – Do not pursue economy of scale
