It is already a form of injustice that would have a negative impact and potential to be a major problem when done continuously. The manager should be able to provide value to the objective, since managers are people who are deemed able to perform such a system. Aside from that position is the belief that should not be wasted, because the employees are not robbed equality subjective assessments.
While the distortion factor that inadvertently due to performance assessment information obtained by observations that are stored in the memory without a note and then recalled to complete a performance assessment, it is a fairly complex task, so the forgetting factor could happen. A systematic record keeping is very doubtful actualization and beliefs. This could potentially lead to the subjectivity of assessment for the procedure of assessment is only done by memory.
