Seeking Advice on Enhancing a Grading System for Logistics HR Policies

I have recently joined a logistics company where I am planning to implement a grading system, which will later be linked with all other HR policies such as reimbursements and more. I would appreciate it if anyone could help me in framing the system. I have drafted one, but the management wants to add more layers, especially below the state head, like state-level coordinators, etc. Please provide your valuable suggestions to enhance the framework.

Attached is the draft I have prepared.

Very nice to meet you on this site. I am working in electronic media and I am attaching my organization's managerial grading, which may be useful for framing.

The number of grades would depend on the number of people in the organization and at which level there is a concentration of people. Organizations with a large workforce would require more layers, whereas organizations with comparatively fewer people would need fewer layers in order to retain employees.

It's desirable that grades, once fixed, be revisited every 3-5 years.
