Why it matters
People are wired to support what they help create (the IKEA effect). Top-down blueprints breed compliance; co-creation breeds commitment. Leaving a meaningful part of the plan open gives people the chance to "crack the egg" — and they will fight to make it work.
How to run it
- Prepare a deliberately unfinished draft. Make the purpose and constraints crystal clear; leave the approach open.
- Name what's fixed and what's open. People must know which decisions are genuinely theirs.
- Let the team build — sticky notes, small groups, real debate. Let it get messy.
- Decide together on the shape of the plan.
- Show the fingerprints. Point out what changed because of the team's ideas — that's what turns input into ownership.
It won't be a perfect process. But it will be theirs.
Watch out for
- Fake participation — if the decision is already made, people notice instantly
- Leaving everything open, so the team has no clear purpose to build towards
- Never showing what changed because of the team’s input
When not to use it
For genuinely fixed constraints (legal, safety, budget ceilings) — say so upfront and invite co-creation only where input can truly shape the result.
