Dear Sarfaraznawaz Desai,
Deep evaluation or otherwise, while evaluating the performance of the HODs or other managers, we need to identify the costs and ratios associated with their departments and assign them. This is the best method of evaluating their performance.
If you had given information about your company's nature of business, finished product or service, major departments, etc., I would have given examples of what I have proposed.
Recently, I provided consulting services to establish an operational performance management system. In management science, this concept does not exist. However, my client hired my services to identify the costs and ratios. After identifying them, I assigned them to the respective HOD. If you wish to know more about it, then you can [click here](https://www.linkedin.com/posts/dineshdivekar_recently-i-provided-consulting-services-activity-7271720220396826625-1j8b?utm_source=share&utm_medium=member_desktop&li pi=urn%3Ali%3Apage%3Ad_flagship3_feed%3BJT8O6hRqQi KT7rETq06ajA%3D%3D).
