Uniform employee performance appraisal
Where I work, engineers report to one or more project managers in a year, depending upon the number of projects they have worked on in that year. It has been observed that different project managers rate the person differently for a particular skill or attribute.
For example, if an engineer worked with two project managers in a year, he is assessed at 3.5 on a scale of 5 for communication by one PM and at 4.2 by the second PM. The same goes for other factors on which he is assessed.
What we essentially want is a uniform grading system for all employees that is relatively independent of the person who is grading.
Your thoughts on how we can achieve this and any pointers to performance appraisal templates would be a great help.
