Purpose
Guide requirements engineers through the Wiegers value/cost/risk priority model to produce a defensible, quantitative prioritization of requirements. This model replaces subjective "high/medium/low" rankings with a multi-factor scoring system that makes trade-offs explicit and traceable.
This is not a popularity contest or a voting exercise. It is a structured analysis that forces stakeholders to consider both the value of having a feature and the cost and risk of building it.
Key Concepts
The Four Scoring Dimensions
Each requirement is scored on four dimensions using a 1-9 relative scale:
- Relative Benefit (1-9) -- How much the customer or business benefits if this requirement is included. Score 9 for maximum benefit; score 1 for minimal benefit.
- Relative Penalty (1-9) -- How much the customer or business suffers if this requirement is not included. Score 9 for severe penalty (regulatory violation, competitive loss); score 1 for negligible impact.
- Relative Cost (1-9) -- How expensive this requirement is to implement relative to other requirements. Score 9 for most expensive; score 1 for least expensive.
- Relative Risk (1-9) -- How much technical risk or uncertainty this requirement carries. Score 9 for highest risk (new technology, unclear feasibility); score 1 for well-understood implementation.
