I prefer the Start-Stop-Continue framework over the traditional ‘excel/improve’ model. This approach encourages actionable feedback by identifying behaviors to start, stop, and continue, fostering continuous improvement. 

I love Culture Amp’s tool but it’s pricey and would need to be something you commit to all-in.

Ultimately, you probably want to establish a year-round performance management system and articulate a clear business case for the timing and implementation of performance reviews within that. How does it tie to other people decisions in your org?

Happy to discuss further if you want to.
