How To Plan A Project Without Overplanning It

Overplanning feels safe because it creates detail. The problem is that early detail often changes before it becomes useful.

Start with the outcome

Write what will be true when the project is done. This is more useful than a long activity list because it keeps the work tied to a result.

Identify unknowns early

Unknowns deserve attention before polish. What could block the work, change the scope, or require someone else's decision?

Plan the next checkpoint

You do not need every step. You need the next checkpoint, the work required to reach it, and the decision that happens there.
