Module 3 · Lesson 16 of 17
Establishing an evidence-based project goal
This lesson and the entire Lean Six Sigma Black Belt academy are free of charge — no fees, ever.
Learning objectives
- Refine Define targets against validated Measure evidence.
- Distinguish entitlement, benchmark and technical limit.
- Set guardrails and revise expected benefits.
Evidence-based goal setting
Once the baseline is trusted, compare it to the best demonstrated subgroup, technical entitlement and any external benchmark. The goal should be achievable, defensible and time-bound.
Recalculate the benefit case whenever the baseline moves; a charter target must not survive against contrary evidence.
Garment-factory example
Best stable lines run at 3.2 DHU while the project line averages 8.5. A staged target of 4.0 within 12 weeks is supported; a ‘zero defect’ claim is not.
Method
- Validate the baseline.
- Estimate the gap and entitlement.
- Model the benefit under the new target.
- Agree guardrails so other CTQs are not damaged.
Common mistakes
- Keeping a charter target after data disprove it.
- Choosing a target only because leadership prefers a round number.
