A guide to evaluation frameworks
Real methods for turning a fuzzy decision into clear, defensible criteria.
Core frameworks
- Weighted sum model — Score each option on each criterion, multiply by importance weight, and total the results.
- Analytic Hierarchy Process — Saaty's 1980s method for pairwise-comparing criteria to derive consistent weights.
- TOPSIS — Ranks options by closeness to an ideal solution and distance from the worst case.
- Pugh matrix — Compares options against a baseline (better, worse, same) per criterion for quick screening.
Applying criteria
- Hiring rubrics — Defining must-have vs nice-to-have criteria before reviewing candidates, to reduce bias.
- Vendor scorecards — Weighting cost, quality, reliability, and support when comparing suppliers.
- Grading rubrics — Breaking an assignment into scored criteria so evaluation is consistent across students.
Common pitfalls
- Double-counting — Overlapping criteria (e.g. 'quality' and 'reliability') can silently double their real weight.
- Arbitrary weighting — Weights chosen without justification undermine the credibility of the whole evaluation.
- Confirmation bias — Scoring a preferred option generously without realizing it skews supposedly objective criteria.
