Start from the constraint, not the goal

Define the hardest boundary first, then generate within it — rather than generating freely and pruning to the constraint.

Why it works

When constraints are applied after free generation, they function as filters — reducing what was already created. When constraints are applied before generation, they function as frames — shaping what is created from the start. Generation-within-frame produces different ideas than generation-then-filter because the initial cognitive search is pointed at the constraint-compatible territory rather than the full space.

How to do it

1. Identify the non-negotiable constraint first: the budget ceiling, the one-day timeline, the two-person team.
2. Do not begin generating solutions until the hardest constraint is explicitly stated and visible.
3. Generate solutions designed from the start to satisfy the constraint — not solutions adapted afterward.
4. Compare the results to a previous unconstrained session on the same problem and note the differences.

Evidence

Geneplore model research (Finke, Ward & Smith, 1992) suggests that creative cognition involves generation followed by exploration; constraining the generation phase changes the space explored. Starting from constraint changes what gets generated, not just what survives screening. (mechanistic)

The specific protocol of stating the constraint before versus after generation is a practitioner derivation from creative cognition theory; direct comparison in controlled studies is limited.

Common mistake

Treating the constraint as the enemy and generating against it ("ignore the budget for now and we’ll figure it out") — which produces ideas that require the constraint to be negotiated away, adding friction and reducing follow-through.
