I have been reporting to my manager for the last two years, but for the past six months, I have been working closely with another manager on a different project. My concern is that my reporting manager, who will decide my appraisal, might not have full visibility into my contributions. Since there is no 360-degree feedback process, how can I effectively showcase my work and ensure I get a fair hike? Any advice on preparing for upcoming discussions would be appreciated!
When you are submitting your appraisal, you will obviously share your achievements and impact.
Something else that you can add - request comments and feedback from people you have worked closely with and add quote their comments/feedback in your appraisal. Basically, you could request your own 360 feedback and share those with your appraisal.
Another suggestion would be to proactively ask your manager how he/she would consider feedback for the project where you are working with the other manager. They could also directly reach out to the other manager or may suggest how they would like to receive it.
Hope this helps.
