Overview
“Objective criteria–means operational definitions and repeatable measurement, not the absence of values. This aligns with A2 and corollary T1.2: weights are conditional and reviews embed assumptions.[^1]
1. A practical recipe (SMART)
Criteria should be:
- Specific
- Measurable
- Achievable
- Relevant (to the user’s needs)
- Time-bound (measurement conditions)
2. Avoiding false objectivity
Good practice:
- state the user model (needs, constraints),
- publish the scoring rubric,
- separate facts (measurements) from values (weights).
3. Standards context (English-world orientation)
Depending on category, objective criteria often rely on test methods from:
- ISO/IEC (domain-dependent),
- ASTM (materials/testing),
- NIST guidance (security-related).
Standards are baselines. They do not remove the need to state weights explicitly.[^2]
