The Core Principles Behind Writing Great Performance Review Feedback
Don't procrastinate writing performance review feedback, especially for your peers! It's such a intimate, powerful thing, and if you truly enjoy working with your peers, they deserve meaty, thoughtful feedback from you.
Keep it organized
Have clear sections. If your company has performance review axes, these can usually be used as your sections.
Use bullet points. People hate reading essays and paragraphs.
Be concise: Use your word count efficiently and avoid repeating yourself.
A lot of resume feedback applies to performance review as well. Use strong verbs, show the impact, and "Show, don't tell".
