Staff evaluation is an instrument of monitoring staff functioning and is a element of promotion in contemporary companies. In some companies, for instance, workers and their immediate line managers talk about personal ambitions and goals for the certain time period of time (like the next four months). The assessment will then include a review of functioning during the previous four months, and setting new objectives. Job details can be a useful basis for creating dialogue and targets. Job descriptions could be used as reference points for mediating in disputes as to ‘who does what’ in a company.
