Problem Statement Criteria

A good problem statement:

• Specific - Clear and measurable
• Observable - Based on data/facts
• Non-judgmental - No blame
• Gap-focused - Current vs. target
• Bounded - Defined scope

Example

Poor: "Quality is bad" Good: "Defect rate on Line 3 increased from 2% to 5% in Q4 2025"
