Dependencies and blockers
Work has an order. The venue has to be booked before the invitations go out, and the API task is stuck until the client sends their requirements. Plankwork records these waits on the task, so you can see which work is ready to start, which work is held up and who or what is holding it.
A blocker says what a task is waiting on: another task on the same board, or someone outside the team. Cards show what holds them up and what they hold up. A filter lists the work you can start now. Every wait that ends is kept, so the Delay ledger can trace where late days came from. A task also keeps a baseline of its original dates, so you can see how far it has slipped.
The full chapter, with every step and setting, is in the app: open your account menu and select User manual.
