Personally I agree that these should be simplified, to make these relevant to the staff - otherwise you end up have an administrative process that is not used (or used effectively) because it is not seen as relevant or useful. I believe that it is possible to have a system where appraisal documents/processes are different based on the types of roles. I think you can have a checklist (tick list), but this needs to be part of a system or culture where the conversations about performance are ongoing - it is the regular feedback that is important.
Dunno if that helps, just my opinion
