Objectives
Set what you're working on.
Not for your manager — for you. Define the things that matter and track them over time. Having it written down is the first step to being able to prove it.
Updates
Log as you go.
Thirty seconds at a time, not two weeks at the end of the year. Tag each entry as an action, a result, or a learning. The record builds itself.
Private
Yours alone.
No manager view, no sharing, no HR dashboard. A record only you can see — which means you can be honest about what's happening, not just what looks good.
Retrievable
Ready when you need it.
Everything is timestamped. When the review or the interview comes, the record is there. "Tell me about a time you had significant impact" — answered.
