Section 29 of 105
28. Rationale and Intended Outcome
Stable section ID: S05-CON-014-SECTION-29 · 16 content blocks
Every Rule should include a rationale explaining why the Rule exists and an intended outcome explaining what system-level condition it is designed to preserve.
Rationale may identify:
- Constitutional source.
- Hazard or failure mode.
- Interoperability need.
- Lifecycle consequence.
- Historical evidence.
- Human-factors concern.
- Digital or security dependency.
- Regional implementation need.
- Economic or environmental objective.
- The intended outcome shall describe the desired engineering state without adding hidden requirements.
Rationale and intended outcome shall remain informative unless explicitly incorporated into the normative statement. They may guide interpretation, review, and future revision but shall not be used to invent obligations that the approved Rule does not state.
A Rule shall not be justified solely by tradition, manufacturer preference, market dominance, or the existence of a previous solution.
Where a Rule imposes cost, complexity, restricted choice, or additional evidence requirements, the rationale shall explain why the burden is proportionate to the protected outcome.
If later evidence shows that the Rule does not achieve its intended outcome, the Rule shall be reviewed even if formal compliance remains high.
