Leadership Development Tracks?

Hello ATD Healthcare Community!
At our hospital we are keen to move towards professional development of our Physician leaders. Presently we provide Continuing Medical Education (largely technical). In addition Physicians attend training programmes of their choice.
I am reaching out to inquire ..."Is there a formal framework that will help us identify the pathway for professional development of our Physician leaders?" ...one that is well researched

I have seen a trend toward informal leadership (see the book Blue Collar Leadership), particularly given that not all of our staff aspire to people leadership positions. Some organizations of which I have been a part have the following promotional tracks:
- Management
- Project Management
- Technical (equivalent to discipline expertise)
This prevented those who wanted to advance from having to choose people leadership roles that they didn't want or weren't well-suited to assume.

I have seen the following in my current healthcare organization, but keep in mind that I work in a public sector organization so there are no president/vice president type titles meaning a "manager" in my department (equivalent to an agency) might have the title of director or higher at another organizational type:
1. Executive (Executive and Deputy Directors)
2. Senior (Directors)
3. Middle Manager (Managers)
4. Supervisory (Supervisors)
5. New Managers (Recently promoted)
