Module 5 · Lesson 5 of 17
Solution screening against CTQs
This lesson and the entire Lean Six Sigma Black Belt academy are free of charge — no fees, ever.
Learning objectives
- Explain the purpose of solution screening against ctqs in a garment-factory improvement project.
- Apply the described method to a representative shop-floor situation.
- Recognize the common mistakes and how to avoid them.
Concept
Early screening removes ideas that cannot meet CTQs, safety, legal, quality, capacity, or sustainability constraints.
Separate non-negotiable gates from weighted preferences to prevent trading safety for speed.
Include worker safety, chemical compliance, buyer requirements, environmental impact, maintainability, and scalability.
Garment-factory example
A faster curing setting fails screening if shade fastness or restricted-substance risk becomes unacceptable, regardless of throughput gain.
Method
- Translate CTQs to measurable thresholds.
- Screen against gates using evidence.
- Record reason for each rejection.
- Improve or drop failed options.
Common mistakes
- Weighting a legal requirement as negotiable.
- Screening with vague words such as 'good enough'.
Knowledge check
