Based on occupation & activities, God created the following 4 Varnas:
Brahmins - predisposed toward teaching and worship (how to get the God or go to heaven)
Kshatriyas - inclined toward administration and management of the kingdom
Vaishyas - form the business and agricultural class (Businessmen)
Shudras - working class (The actual person who works)
In the same way, we also need 4 Departments in our Business.
Brahmins - Marketing - Do the marketing & they actually help us to meet our God (Our Customer).
Kshtriya - HR - Form a Business, Hire Team, Appoint People, Make Policies, define Penalties, etc.
Vaishyas - Operations - Administration & Management (or your Top Management Team).
Shudra - Technical - Actual working people, our employees who actually do work
Simply, Be the God of your Organization.
