10 Think Toolkits to Master Divergent-Convergent Creative Problem-Solving

 

Creative problem-solving requires two opposite mental modes: explosion and implosion. These ten toolkits help you systematically expand possibilities then contract to solutions, avoiding the trap of premature convergence while preventing endless divergence.

1. The Expansion-Contraction Timer

How to apply it: Strictly separate divergent and convergent phases with time boundaries.

The timing method: Phase 1: Diverge (expand options)

  • No judgment allowed
  • Quantity over quality
  • Wild ideas welcomed
  • Build on everything

Phase 2: Converge (narrow options)

  • Judgment required
  • Quality over quantity
  • Practical constraints
  • Select best ideas

Timing ratios: Simple problems: 20 min diverge, 10 min converge Complex problems: 2 hours diverge, 1 hour converge Major decisions: Days diverge, hours converge

Your timer: Problem complexity: _____ Divergent time: _____ Convergent time: _____ No mixing phases: _____

Think: "Mixing modes kills both—diverge fully, then converge completely"

2. The Yes-And Multiplier

How to apply it: Use "yes, and" to expand ideas during divergent phase.

The multiplication method: Idea presented Respond: "Yes, and..." Build on it Generate more

Multiplier examples: "Remote work" → "Yes, and from anywhere in world" "Yes, and while traveling" → "Yes, and with team meetups" "Yes, and in different time zones" → "Yes, and async everything"

Killer phrases to avoid:

  • "Yes, but..." (convergent thinking)
  • "That won't work because..." (premature judgment)
  • "We tried that..." (historical limits)

Your multiplier: Initial idea: _____ Yes, and: _____ Yes, and: _____ Yes, and: _____

Think: "But kills ideas, and multiplies them—stay in expansion mode"

3. The Criteria Clarifier

How to apply it: Before converging, establish clear evaluation criteria.

The clarification method: End divergent phase Pause before convergent Define success criteria Apply systematically

Criteria categories:

  • Must have (non-negotiable)
  • Should have (important)
  • Could have (nice additions)
  • Won't have (boundaries)

Your clarifier: Must have: _____ Should have: _____ Could have: _____ Won't have: _____ Now evaluate ideas

Think: "Unclear criteria create biased selection—clarify before choosing"

4. The Quantity Quota Setter

How to apply it: Set minimum idea quotas to prevent premature convergence.

The quota method: Set ambitious target Generate that many minimum Only then evaluate Forces exhaustive exploration

Quota guidelines: Simple problem: 20 ideas minimum Complex problem: 50 ideas minimum Strategic decision: 100 options minimum

Quota benefits:

  • Prevents first-idea fixation
  • Forces creative stretching
  • Reveals unexpected options
  • Builds idea confidence

Your quota: Problem: _____ Minimum ideas: _____ Actually generated: _____ Best idea position: _____ (usually after #20)

Think: "First ideas are obvious—set quotas to reach breakthrough territory"

5. The Assumption Eliminator

How to apply it: Remove constraints during divergent phase, add back during convergent.

The elimination method: List all assumptions Temporarily remove each Generate ideas without limits Add constraints back when converging

Assumption examples: "Must be profitable" → Explore loss leaders "Must use existing team" → Consider outsourcing "Must launch this year" → Consider timing options "Must be perfect" → Consider MVP approaches

Your eliminator: Assumptions limiting: _____ Removed temporarily: _____ New possibilities: _____ Reality added back: _____

Think: "Assumptions limit imagination—remove to explore, restore to execute"

6. The Forced Connection Maker

How to apply it: Force connections between unrelated ideas to create hybrids.

The connection method: Idea A + Idea B = Hybrid C Force combination Even if seems impossible New solutions emerge

Connection examples: Uber + Healthcare = House calls Netflix + Education = Skill streaming Airbnb + Coworking = Space sharing Amazon + Groceries = Instant delivery

Your connector: Idea 1: _____ Idea 2: _____ Forced connection: _____ Hybrid solution: _____

Think: "Best solutions are idea marriages—force connections between strangers"

7. The Devil's Advocate Rotator

How to apply it: Systematically attack each idea from different perspectives during convergence.

The rotation method: Each idea gets challenged by:

  • Customer perspective
  • Competitor perspective
  • Resource perspective
  • Risk perspective
  • Implementation perspective

Rotation questions: Customer: "Why would they care?" Competitor: "How would they respond?" Resource: "Can we actually do this?" Risk: "What could go wrong?" Implementation: "How would this work?"

Your rotator: Top idea: _____ Customer challenge: _____ Competitor threat: _____ Resource gap: _____ Risk identified: _____

Think: "Unopposed ideas are untested—rotate attacks to strengthen survivors"

8. The Energy Investment Calculator

How to apply it: Evaluate ideas based on energy required versus impact delivered.

The calculation method: For each idea: Energy needed (1-10) Impact potential (1-10) Calculate ratio: Impact ÷ Energy

Energy factors:

  • Time required
  • Money needed
  • People involved
  • Skill gaps
  • Complexity level

Your calculator: Idea: _____ Energy needed: ___/10 Impact potential: ___/10 Ratio: _____ Priority ranking: _____

Think: "Energy is finite—maximize impact per unit invested"

9. The Prototype Validator

How to apply it: Create quick tests for promising ideas before full commitment.

The validation method: Select top 3 ideas Create minimum viable test Get real feedback Let data guide final decision

Prototype types:

  • Landing page (test interest)
  • Paper prototype (test usability)
  • Role play (test process)
  • Survey (test demand)
  • Pilot program (test execution)

Your validator: Idea to test: _____ Prototype method: _____ Success metric: _____ Test result: _____

Think: "Opinions are cheap, data is expensive—prototype to validate"

10. The Implementation Roadmapper

How to apply it: Map implementation path for final selections.

The roadmapping method: Selected solution Break into phases Identify dependencies Create timeline Assign resources

Roadmap elements: Phase 1: Quick wins (build momentum) Phase 2: Foundation building Phase 3: Scale and optimization Dependencies: What must happen first Milestones: Decision/review points

Your roadmapper: Final solution: _____ Phase 1: _____ Phase 2: _____ Phase 3: _____ First step: _____

Think: "Great ideas need great execution—map the journey from concept to reality"

Integration System

Divergent sessions: Use timer + quotas + yes-and Transition: Clarify criteria + remove assumptions Convergent sessions: Use devil's advocate + energy calculator Validation: Prototype + roadmap

The creative formula: Timed expansion + Quota-driven generation + Criteria-based evaluation + Prototype validation = Creative mastery

Evolution:

  • Session 1: Learning the modes
  • Month 1: Natural phase switching
  • Month 6: Advanced technique mastery
  • Year 1: Creative problem-solving expert

Master divergent-convergent thinking: Expand like there are no limits, contract like resources are scarce—master both to master creativity.
