Expert Decision Matrix

INTRODUCTION
English translation pending.
CORE DEFINITION
A decision tool that arranges options against evaluation criteria in a grid, has experts score each cell, and combines the scores using weights to produce a comparable basis. Its core proposition is that forcing criteria and weights into the open converts an opaque judgment into a structure that can be inspected and challenged, reducing the influence of unstated preference. The qualifier is that the weights themselves carry judgment, so the output reflects assumptions rather than objectivity.
SCAFFOLDING EFFECT
Reduce cognitive load
- Criteria listing: name every dimension on which the competing options should be compared. - Weight assignment: state the relative importance of each criterion explicitly rather than implicitly. - Assumption disclosure: report the weights and the scores so others can challenge the reasoning.
Anchor fast decisions
Comparing options in the head allows whichever factor is most vivid to dominate and hides the trade-offs being made. Writing criteria and weights into a grid forces every factor to be considered at the same time and makes the relative importance of each visible, so the decision can be examined rather than merely asserted.
