Finish, then flow
Finish, then flow is the practice of pulling the next most valuable goal immediately when the current one reaches its outcome, rather than waiting for the next planning ceremony. The quarterly heartbeat stays fixed; the work does not idle inside it.

The waste it removes
A team finishes in week seven. The next planning session is in week thirteen. What happens in between is either invented work or a slow drift back to business-as-usual, and both are expensive.
Nobody designs this. It is a side effect of treating the planning ceremony as the only moment a goal is allowed to start.
What it requires
A maintained list of what is next, ordered by value, so the answer to "what now" exists before the question is asked. Without that list, finishing early just creates a scramble.
And permission. The team has to be allowed to start the next thing without convening the leadership team, which means the ordering decision was made in advance rather than on demand.
Banking the learning first
The pull happens after the ten minutes that closes the goal properly: what happened, what was learned, what is worth keeping. Skipping that to get on with the next thing is how a company runs fast and remembers nothing.
What does finish, then flow mean? +
When a goal reaches its outcome, the team banks the learning and pulls the next most valuable goal straight away instead of waiting for the next planning ceremony.
Does that break the quarterly cycle? +
No. The quarterly heartbeat stays fixed for review and reprioritisation. What changes is that goals are allowed to start and finish inside it rather than being forced to the boundaries.
