Why 90 days
Ninety days is long enough to finish real work and short enough to stay focused. Annual plans drift; weekly plans react. A quarter is the right size for fixing one constraint properly.
The one-page structure
| Section | What to write |
|---|---|
| Goal | One number and a date, e.g. “repeat purchase rate from X% to Y% by 31 March”. |
| Constraint | The single thing most limiting growth now, with the evidence. |
| Priorities (max 3) | The projects that attack the constraint. |
| Owners | One named person per priority. |
| Weekly measures | A leading indicator for each priority. |
| Not now | Good ideas you are deliberately postponing. |
| Review rhythm | A 30-minute check every two weeks; a full review at day 90. |
How to run it
- Week 1: agree the goal, constraint and priorities with the people who will do the work.
- Every week: each owner updates their measure in one shared sheet.
- Every two weeks: 30 minutes: what moved, what’s stuck, what we’ll change.
- Day 90: did we hit the goal? What’s the next constraint?
From our work: [A 90-day plan from a PURSHO engagement (anonymised), with the goal, priorities and outcome]
Common mistakes
- Too many priorities, so nothing gets finished.
- Measures nobody checks until the end.
- No “not now” list, so new ideas quietly take over.
We build these plans with clients in our growth consulting engagements.
