If you keep reopening the same decisions, you do not have a decision problem. You have a decision memory problem.
Debate is useful early. Repeated debate later is expensive.
Why decisions loop
Usually one of these is missing:
- clear decision record
- criteria used to decide
- linkage to affected work
- accountable owner
Without these, new stakeholders reset the conversation.
What to do instead
Record each decision with:
- what was decided
- why it was decided
- what it changes
- when it should be reviewed
That turns debate into progress.
