The Evidence Habit: Arriving at Your Appraisal With Proof Rather Than Adjectives

There is a particular kind of silence that settles over a review meeting when someone asks for an example. The year has been full, the diary has been unrelenting, and yet the specifics refuse to surface. What follows is usually an adjective: busy, stretched, supportive, committed. None of these will move a pay band.
The gap is rarely one of performance. It is one of record-keeping. Work that is not written down at the moment it happens has a half-life of roughly a fortnight, after which it becomes a general impression rather than a demonstrable fact. By the time appraisal season arrives, the strongest material has usually been overwritten by whatever happened most recently.
Why recollection fails under pressure
Memory is reconstructive, and it reconstructs in favour of the latest and loudest. A difficult February project will be recalled as 'challenging' rather than as the specific thing that was delivered three weeks early, because the emotional residue outlasts the operational detail. Add to that the natural diffidence of many UK professionals — a reluctance to appear to be boasting — and the result is a review in which the person being appraised does most of the apologising.
A written record corrects for both. It does not make anyone more assertive; it simply removes the need to perform confidence from memory in a room where the other party holds the notes.
What counts as evidence, and what does not
Evidence is anything that a reasonable third party could verify or repeat. It is not the same as effort, and it is worth being firm about the distinction.
- Quantities. Volumes handled, cycle times reduced, error rates, response times, revenue retained, cost avoided. Even a rough figure is more persuasive than none, provided you say it is rough.
- Named outcomes. A process that now runs without a weekly meeting. A handover that no longer needs your involvement. A client who renewed.
- Verbatim feedback. Two or three sentences copied exactly, with the date and the source, carry more weight than a paragraph of paraphrase.
- Decisions you influenced. Particularly the ones where you were not the most senior person in the room.
- Things you stopped doing. Retired reports, discontinued meetings, work that was quietly absorbed elsewhere. These are reductions in organisational drag and are routinely invisible.
What does not count: adjectives, unquantified claims of 'leading' or 'driving', and any description of a task that omits what changed as a result.
The fifteen-minute November sort
Set aside a quarter of an hour in the first fortnight of November. The timing matters for two reasons: the year is still open, so the record can be completed rather than merely recalled; and there is usually enough distance from the busiest period to think clearly.
The exercise is deliberately small. Open a single document and create five columns. Then work backwards through the diary, month by month, and mine it for three things only: what was delivered, what was measured, and who said thank you.
The diary is an underused source. Recurring meetings that you instigated, deadlines you met, and the weeks where you covered for someone else are all recorded there. Ten minutes of scrolling will usually produce more concrete material than an hour of trying to remember.
A template worth keeping
| Date | What happened | Who noticed | Measure or quote | So what |
|---|---|---|---|---|
| 14 Feb | Took over the supplier reconciliation after the team absence | Finance lead | Closed 11 days earlier than the previous quarter | Removed a recurring pressure point in month-end |
| 22 May | Rewrote the onboarding checklist | Two new starters, line manager | Induction queries down from roughly six a week to two | Freed supervisory time |
The final column is the one most people omit, and it is the one that does the work. It converts an activity into a consequence. Managers can read a list of activities and remain unmoved; a list of consequences invites a different conversation.
Handling the near-misses honestly
Not everything belongs in the wins column, and a record that contains only successes will be discounted as marketing. Keep a short section for things that did not land: the project that stalled, the restructure you misjudged, the stakeholder you never quite brought round.
Write each one in three lines — what happened, what you learned, what changed in your approach afterwards. This does two things. It demonstrates judgement rather than luck, and it removes the element of surprise if the subject comes up. A candidate who raises their own setback first controls the framing of it.
If you manage people, start the conversation in November
Line managers shape whether this happens. A short message in early November — asking each team member to bring three examples of work that made a difference, with numbers where possible, to a fifteen-minute one-to-one — changes the quality of every appraisal that follows. It also signals that the organisation takes the process seriously.
Two practical points for managers. First, do the same exercise yourself; nothing undermines the request faster than a manager who has not done it. Second, use the one-to-one to fill gaps rather than to correct claims. If someone cannot evidence something, ask what evidence would look like, and whether it can still be captured before the year closes.
After the sort
Keep the document. Append to it in the weeks that follow, then put a recurring fifteen-minute slot in the diary for the first Monday of each month in 2026. The annual sort becomes a review of an existing record rather than an act of excavation.
The practical effect is not that anyone becomes better at their job in November. It is that the work already done becomes visible at the point where visibility carries a price. A year of effort deserves better than a sentence containing the word 'busy'.
