In a large concern employing fifty or more staff, some kind of a formal reporting system is needed in order to achieve systematic assessments of which full account can be taken when people's future careers are being considered. The report form itself should as far as possible be self-explanatory and self-contained, so that the Reporting Officer knows what is expected of him. In view of the large number of Reporting Officers operating in any large organisation, the training courses required to cover all of them consume an enormous amount of time on the part of trainers and Reporting Officers alike. This decision enabled training courses to be concentrated on developing skills in appraisal interviewing. In order for staff reports to enjoy the confidence both of management and of staff, every effort should be made to ensure that they are related to common standards. Written staff reports provide much relevant information about a person's performance in the job.
