You can adopt function-wise analysis to determine how much manpower each function requires. For example, finance, marketing, maintenance, or packaging.
Then conduct role-wise analysis in each function to understand how many roles are necessary to perform each function. A function is carried out through various roles such as Finance Manager, Finance Officer, Finance Executive, and Accounts Clerk/Assistant.
Next, identify the gap between the required number of roles and the current workforce manning those roles.
Additionally, factor in the number of employees likely to retire within a year.
Consider the additional manpower needed both role-wise and function-wise, taking into account any business expansion plans and the timeframe in which they are required.
Take into consideration any modernization plans that may reduce manual processes.
These are broad guidelines that can assist in manpower planning.
