The most powerful approach layers multiple constraints strategically:
Basic Constraint Stack
```text Start with core task: "Create a customer onboarding flow"
Add constraints progressively: + Time: "Completes in under 2 minutes" + Format: "Using only yes/no questions" + Technology: "Works via SMS only" + Personality: "Feels like texting a funny friend" + Outcome: "80% completion rate"
Final result: A revolutionary onboarding experience ```text
Advanced Constraint Stack
```text Base: "Design a loyalty program"
Layer 1 - Resource Constraints: + No points or rewards + Zero technology required + Costs nothing to implement
Layer 2 - Experience Constraints: + Customers don't know they're in it + No signup process + Works for one-time visitors
Layer 3 - Business Constraints: + Increases average order 30% + Requires no staff training + Measurable within one week
Result: "The Secret Menu Society" - where observant customers discover hidden menu combinations that unlock experiences, creating an organic word-of-mouth community ```text
