Seeking Advice on Building a Performance Management System for a Large Manufacturing Team

I am looking forward to having your kind help in developing a performance management system for a manufacturing company. Our manpower strength is as follows:

1) AM, DM, Manager, Sr. Manager, AGM, DGM, VP (Corporate & Plant): 170
2) Executive (Corporate & Plant): 250
3) Company on-rolls workers: 750

Kindly share documents, reports, findings, etc., if someone has experience with performance appraisals for such a large team in a manufacturing unit. Looking forward to your support.

Importance of Performance Standards and Observations in Appraisals

Job performance appraisals should focus on an individual's actions throughout the rating period as compared to specific performance standards. Before an appraisal can be written, the employee must know what the standards are. Without clearly communicated performance standards, the employee will not understand why they were rated as they were on the appraisal.

The second prerequisite for a job performance appraisal is observations of job performance. Without these, you cannot know how well the employee has met the standards.
