How do you define a top performer? What are the qualities they have? Any research links will also be helpful. Thanks!
The honest (and unhelpful) answer is that this is something for you to define. A top performer for our company may not be so at yours. We may value different attributes and behaviours.
I am sure there is data out there to tell you what ‘talent’ looks like, but my advice is to start with what matters to you.
