Performance reviews depend on accurately recalling 12 months of work. Most people remember the last 2-3 months clearly and the earlier 9 months vaguely. A simple ongoing 'wins file' fixes this and transforms annual reviews.
What to track
Specific accomplishments with metrics where possible. Positive feedback received (from managers, peers, customers — paste verbatim). Projects completed with their outcomes. Strategic contributions beyond your role. Numbers wherever they exist.
Why it pays off
Annual reviews backed by specific evidence land differently than vague 'I think I did well'. Manager doesn't have to remember; you bring the data. Promotion conversations get easier. Salary negotiations get easier. Job interviews get easier.
Five minutes weekly is enough. The compound effect over years is significant — both for your own clarity about your career and for the leverage it gives you in every conversation about your value.
