Product specs
Plan the feature in a doc, turn its to-dos into cards on the board, and see each one through to done.

Write the spec
The outcome, the flow and how you will know it worked, with headings and to-dos from one menu.

Turn to-dos into tasks
Each to-do in the spec becomes a card on the board. The two stay linked.

Track it on the board
Every card carries a priority, an owner and the criteria that say when it is done.
