09 — Appendix: Questions That Keep the Story Honest

This appendix preserves the full question map from the source research so coverage is not lost to narrative compression. Answers are pointed to chapters; unresolved items stay marked.

P1. What are TRIZ, SIT, and SCAMPER, and how are they related?

• Acronyms, dates, founders → Ch. 02–04
• SIT as TRIZ descendant, not twin → Ch. 03
• SCAMPER on Osborn/Eberle lineage, not TRIZ → Ch. 04
• Shared bottleneck: fixedness / fluent clichés; different search policies → Ch. 01, 05
• Units of work: checklist item / component system / contradiction → Ch. 05
• Systematic vs Systemic naming → Ch. 03
• ASIT, USIT as relatives → Ch. 05

P2. Core mechanism of TRIZ

• Three patent findings; technical vs physical contradiction → Ch. 02
• 40 principles, matrix, IFR, ARIZ, Su-Field, evolution laws, levels → Ch. 02
• Industry footprint and evidence quality → Ch. 02, 06

P3. Core mechanism of SIT

• Why simplify TRIZ; five tools; Closed World; FFF; Path of Most Resistance; virtual product → Ch. 03
• HBR / Inside the Box / commercial practice → Ch. 03
• Non-product domains → Ch. 03, 05

P4. Core mechanism of SCAMPER

• Osborn checklist → Eberle mnemonic → Ch. 04
• Seven operators; session process; strengths/weaknesses → Ch. 04
• Evidence thinner than popularity → Ch. 04, 06

P5. Comparison

• Complexity, domain fit, open vs closed world, sequencing, chooser → Ch. 05

P6. Cognitive science

• Functional fixedness (Duncker candle) → Ch. 01
• Quantity-first brainstorming harm; constraints; interrupt styles → Ch. 01, 06, 07

P7. Criticisms and failure modes

• Full contrarian scan; Design Thinking boundary; when unstructured wins → Ch. 06

P8. AI and EmTech

• LLM execution of operators; hybrid workflow; option volume → Ch. 07

P9. Worked examples

• Hotel key (SIT), library card (SCAMPER), bicycle (all three) → Ch. 03–05
• Origin stories Altshuller / Osborn / Israeli SIT → Ch. 02–04
• Enterprise cases with caveats → Ch. 02, 06

P10. Decision-maker playbook

• Training path, metrics, integration, reading stack → Ch. 08

Explicitly unresolved

• Controlled multi-site RCTs comparing all three on identical problems with implementation outcomes
• Canonical modern TRIZ boundary versus commercial variants for non-specialists
• Whether Closed World systematically underperforms on radical category creation
