Executive summary
A method for turning condition data, failure records and scattered engineering judgment into one governed assumption register the maintenance investment case can safely be built on.
What is inside
What the pack covers
The asset takes the signed baseline and readiness outputs, defines the assumption register format, sets rules for ranges, confidence grades and provenance, lays out the research methods for closing registered evidence gaps in condition and failure data, runs the full register through structured challenge, and freezes it as the single input set for the options appraisal.
- Scope: the assumption base behind an energy maintenance prioritization investment case
- Separating observed asset facts from improvement hypotheses before any modeling starts
- Condition, failure, downtime, cost and benefit assumptions stated as ranges with confidence grades
- Provenance rules that make every number in the case auditable
- Research questions for the gaps the baseline diagnostic registered
- Structured challenge and freeze before the options appraisal begins
- Handover into the investment case and the later benefits review
