Requirements Prioritization – Weighted Scoring
Prioritize competing requirements using explicit criteria, percentage weights and evidence-based 1–5 scores. Calculate weighted scores, rank the requirements and test how sensitive the result is to changes in decision assumptions.
Make Requirement Trade-Offs Explicit and Comparable.
Weighted scoring is useful when no single criterion is sufficient to prioritize requirements. The technique combines agreed criteria, relative weights and consistent scores so stakeholders can see why one requirement ranks above another.
- Define criteria that represent distinct decision considerations.
- Assign percentage weights that total 100%.
- Score each requirement consistently on a common 1–5 scale.
- Calculate a weighted average and normalize it to a 0–100 score.
- Rank requirements and then test whether the ranking changes when weights change.
Requirements Prioritization – Weighted Scoring — Step by Step
Eight locked stages move from decision context and criteria through calculation, ranking, sensitivity analysis and management review.

Formula and Decision Rules
Normalized Score (0–100)= Weighted Average × 20
1. Define Criteria
Use distinct decision criteria that reflect the real trade-offs.
2. Assign Weights
Express relative importance and ensure percentage weights total 100%.
3. Score Consistently
Use the same 1–5 interpretation across all requirements and support scores with evidence.
4. Test Sensitivity
Change plausible weights to see whether the ranking is robust or assumption-sensitive.
