What are the best ways to evaluate the performance of employees in the organization/company?

You have to prepare a checklist of measurable performance criteria that can be applied to all members of your department, organization, ..etc. When preparing the checklist, you have to keep in mind the following criteria:

1. Performance.

2. Attendence. 

3. Attitude/ Cooperation.

4. Communication Skills.

5. Company Oriented.

6. Focus.

7.Improvement form pervious evaluation.

8. Integrity.

9. Productivity/ Deadlines.

10. Quality of work.

11. Teamwork

12 Stress Managment.

output of employees within definate time and resources

I would think that factual evidence outweighs subjective evidence in this case- where the employee's KPRs are met in the annual performance appraisal report matched by the level of attendance, quality of work and consistency in the quality of work delivered. Another determinant is the amount of business brought to the table.

1. Performance.

2. Attendence. 

3. Attitude/ Cooperation.

4. Communication Skills.

5. Company Oriented.

6. Focus.

7.Improvement form pervious evaluation.

8. Integrity.

9. Productivity/ Deadlines.

10. Quality of work.

11. Teamwork

12 Stress Managment.

I agree...
