I do not understand the performance management process.
My personal experience has included feedback focussed on a minor incident or misunderstanding held during the year (e.g. I did not submit a report on time - even though I was on sick leave!). My rating then focusses on the one incident.
Irrespective of the feedback received from various colleagues, managers hold the ultimate decision on the final rating. My impression is that if you are fully visible and appreciated by your manager and their management team, you will excel.
As a result we risk the quieter, more humble colleagues facing challenges in this process.
Why is the performance management process at the subjective bias of managers?
