What is your organisation capable of?
You measure everything else your organisation does. This measures whether your people will still be doing it in fifteen years — as one number, with the error published, and without exposing a single individual.
Aggregate reporting, and nothing else
Everyone who takes part has their own Index — measured with the team at Grosvenor Square or on site, or by themselves — and it is theirs. You never see it, and it goes with them if they leave. What your organisation sees is the group:
- The spread across the five bands — Reversing, Slipping, Holding, Resilient, Extending.
- The mean and median Index, with the mean interval beside them — how sure the figures are. Nobody else reports it.
- The three domain means — cardiorespiratory, strength and movement capacity. One usually sits lowest, and that is where the budget goes.
- Participation — how many were invited and how many have joined.
- Year-on-year movement on all of it, and the same figures by age group where the groups are large enough.
No individual result, no name, no rank, no list of who has taken part. Ever.
Every figure we show you, and every figure you could work out from the ones we show, is about at least ten people. A smaller group is withheld: not rounded, not blurred, withheld. If withholding one group would still let it be worked out from the total and the others, the next smallest is withheld with it.
Ten is the floor for every contract. Yours can raise it; nothing lowers it, and the database refuses to. This is a privacy feature, not a limitation, and we will not waive it on request. It is the difference between reporting on a workforce and surveilling one.
You see a participation rate, never a roster. Nobody is added; people are invited, and joining is their own yes. You paste your list of addresses as often as you like: anyone new is invited, anyone who has not answered is reminded — at most once a week, three times in all — and you are never told who that was. We do not keep the addresses.
Anyone can leave at any time from their own account. Your figures stop counting them from that day; they keep their account, their history and their Index. A report you have already been issued stays exactly as it was: a report issued in March still says in December what it said in March.
What the report looks like
The numbers below are invented for illustration. They are not a real client, not drawn from the Evolution dataset, and not a benchmark to compare yourself against. They do obey the floor, which is why three bands show no number.
Domain means
Across the five bands
A year on
| Measure | A year before | Now | Movement |
|---|---|---|---|
| Mean Index | 58 | 62 | +4 |
| Mean interval | ±8 | ±6 | 2 narrower |
| Movement capacity | 44 | 49 | +5 |
| Joined, of those invited | 70% | 79% | +9 points |
A movement in a group’s mean is not a change in any one person, and the report never says it is. The mean interval sits beside the means so you can see how much the measurements can carry: as people add measurements it narrows, and the figures become more certain.
Credibility
- The methodology is published in full — the domains, the weighting, the tests, the scoring and the floor rule.
- The error bars are published. Every Index carries its own interval, and every report carries the group’s mean interval beside its mean.
- Assessments are conducted by the Matt Roberts Evolution team at 32 Grosvenor Square, on calibrated equipment, to a scripted protocol.
A scoring system nobody can inspect gets ignored. One that can be inspected — and that states plainly where it is still provisional — gets trusted.
Enquire
