Comparability · Know the difference.

How do these compare? Give the answer some backbone.

Comparability is a platform for evaluating things rigorously and comparing them fairly. One framework, one scale, every judgment traceable — so a difference in the result means a difference in the thing assessed, not in the form someone filled in.

Comparability Replaces
Scattered spreadsheets, one per reviewer. Formats that changed between rounds. A headline score no one can interrogate. One person's recollection of last year.
The model — four objects Sheet 01 Versioned
No. Object What it holds Why it matters
01 Topic Themes, questions, rating scales Defines what good looks like, once, for everyone
02 Target The thing under assessment A coastal corridor, a department, a supplier
03 Assessment Score, trend, confidence, commentary Records the judgment and how sure of it you are
04 Comparison Two targets, or one target through time Helps you understand "is A getting better?" and "Is A better than B or C?"

Every result is traceable to who assessed what, when, and under which version of the framework.

02 · The quiet differentiator

Not just A versus B — A versus last year

Because assessments accumulate against a versioned framework, one-off evaluations become a longitudinal record. Scores decompose into themes, questions, evidence and commentary, so a headline number can always be opened up and argued with.

03 · What it brings

Discipline

Everyone answers the same questions on the same scale. Differences in results reflect differences in the thing assessed, not differences in the form.

Transparency

A score is never a black box. Open it to its themes, its questions, the evidence and the assessor's commentary — then take the conversation from there.

Memory

Frameworks are versioned and assessments accumulate, so organisations stop re-learning what they knew. Progress, decline and drift become visible instead of anecdotal.

04 · Assessment as a group activity

Workspaces, roles, and the rules of contribution

Role Holds responsibility for
AdministratorDesigning topics — themes, questions, scales — and setting policy
Target managerDefining what gets assessed, and curating proposals
AssessorDoing the evaluating — score, trend, confidence, commentary
ReviewerChecking the work before it stands as a result
Topic-level policy
Accumulate or converge Many independent assessments, or one collaborative evaluation the team lands together.
Who may propose targets Open participation with a review step, or a closed register managed centrally.
AI drafting, attributed Assistance can draft themes and questions to accelerate framework design — always under human direction, always named in the audit trail.
Everything logged Who assessed what, when, and under which version of the framework.
05 · Who it's for

Environmental science

Conservation bodies scoring ecologically significant areas against consistent criteria, season after season.

Public sector

Program and data-governance maturity measured the same way across every department, then tracked.

Consultancies

A repeatable, professional instrument to run client assessments on — not another bespoke spreadsheet.

Communities of practice

Networks comparing municipal performance, wine regions or dog breeds, where many judgments must aggregate coherently.

“The question ‘how do these compare?’ deserves an answer people can trust — and keep trusting as the picture changes.”
