Compare Assessments Without Averaging Incompatible Condition Scores
Two reports can use the word condition while measuring different things. Before averaging their scores or ranking assets together, compare the purpose, coverage and rating definitions. A combined number may conceal the most important differences in the underlying evidence.
Read the scale before comparing the value
Identify what each rating describes, who assigned it and which direction represents greater concern. Check whether the scale is descriptive, measured or an internal prioritization tool. The same numeral can carry different meanings in two systems. Do not convert a category into a percentage or add decimal precision unless the method supports that interpretation.
Check dates, coverage and evidence
Compare the asset boundaries, accessible areas, collection dates and methods actually used. One report may describe visible surface conditions while another addresses a narrower specialist question. Those records can complement each other without being interchangeable. A later date does not automatically make an unrelated or less complete review the appropriate replacement for the earlier evidence.
Write the decision comparison in words
State where the reports agree, where they address different questions and what information is still needed. Ask the relevant authors to clarify an apparent conflict rather than silently blending their conclusions. Keep a budget priority separate from a technical finding or an urgency determination. A short comparison table can support a management decision while preserving each report’s scope, limitations and responsible professional role.

Worked example
Illustrative example: a fictional owner receives a surface-maintenance rating and a specialist report about one joint. The team does not average the two scores. It records what each addresses and asks how the findings affect the planned maintenance decision, leaving unsupported comparisons out of the asset ranking.
