The levels
- Milestone — a dated phase you’re aiming for. “What are we trying to be true by when?”
- Enabler — a capability your project needs to acquire to reach that milestone. “What must we be able to do that we can’t do yet?” Think weeks, not days — an enabler is done when the project can do something new.
- Card — one shippable piece of that capability. “What thing needs to exist?” A card is done when that thing exists and works.
- Checklist item — a step inside a card. “What do I do next?”
A quick way to size something
Ask what’s true when it’s finished:- If the answer is “we can now do X” — it’s an enabler.
- If the answer is “this thing exists” — it’s a card.
- If the answer is “I did this one action” — it’s a checklist item.
