For many years, managers were judged by the standards of personal qualities and characteristics of the work. Typical trait-rating systems rating can list 10 to 15 personal characteristics, such as the ability to deal with people, leadership, competency analysis, decision and initiative.
The list can also be work-related characteristics such as expertise, his ability to carry out missions on the production costs or results or achievements to see the plans and instructions to be executed. But until recently, personal qualities are more than compensated for work-related characteristics. Based on these standards, the expert evaluates subordinates, note the remarkable unacceptable.
A practical approach to the problem of assessment is that, because the assessment does not cover can be objective, managers do not seriously want to use their subjective judgments about a matter of course as important as performance. And employees who receive less than the best grade almost always feel treated unfairly.
Criteria are at best unclear. The evaluators are faced with a blunt instrument, and subordinates are probably vague about the qualities on which they are written. In the hands of most practitioners, it is a crude device, and are aware of the reviewers painful, they are reluctant to it in a way that the use would harm careers of their subordinates. A primary goal of assessment is to provide a basis to give the power to discuss and plan for improvement. But the assessments relate to discuss some tangible, regardless of where the participants can be understood as a fact, and therefore little understanding of what is necessary to provide for improvements.
As the inadequacies of the scoring lines have come to be recognized, a number of changes and additions introduced. Some functions have been developed to make it more understandable for evaluators. Often shapes the character and quality of the work of evaluation, which openly, without specific guidelines requested to reviewers, all evidence of the performance they are added to provide relevant.
