I cannot give you a reference, but I think the current consensus is that there is not a uniform way to do this as positions and tasks vary. The part of the evaluation that is based on performance parameters generally should include several bibliometric indicators such as number of papers, number of citations and H-index.
Aradhana Universities today are being subjected to quality control through accreditation process like National Assessment and Accreditation Council (NAAC) in India, British Accreditation Council in UK, Council for Higher Education Accreditation etc. although its a mater of debate- accreditation or none. But the parameters within the accreditation process includes a number of performance parameters that you would be seeking out-Cite factor, H-Index, Researches done and being conducted, patents, innovations, books published, new courses designed, curriculum development, workshops, seminars, conferences conducted at National and International level......Yes even documented case studies within the annals of a history could be used for evaluating performance.....another would be the (employee) teaching as well as non teaching and student satisfaction.
I suggest to look at U-Multirank which offers a large and exhaustive set of parameters.
U-Multirank is particularly interesting because it does not classify universities in comparison to one another, but instead gives to each institution the possibility to identify its strengths and evaluate its level of improvement over time.
