Step 1: Know the two structures:
A functional structure puts people doing the same kind of work into one department. A divisional structure puts people working on the same product into one division. We compare them on formation, specialisation and managerial development.
Step 2: (i) Formation:
Functional structure: it is formed on the basis of functions such as production, sales and finance.
Divisional structure: it is formed on the basis of product lines, and the functions support each product division.
Step 3: (ii) Specialisation:
Functional structure: it offers functional specialisation. Employees become expert in one function.
Divisional structure: it offers product specialisation. Employees become expert in one product or market.
Step 4: (iii) Managerial development:
Functional structure: managerial development is difficult. Each functional manager reports to the top management and handles only one function.
Divisional structure: managerial development is easier. A division head enjoys autonomy and handles several functions, which helps him learn.
Final Answer:
Functional structure is function based with functional specialisation and slow managerial growth. Divisional structure is product based with product specialisation and better managerial growth.
