Step 1: Know the two structures:
Functional structure groups work by function. Divisional structure groups work by product. We compare them on responsibility, cost and coordination.
Step 2: (i) Responsibility:
Functional structure: it is difficult to fix responsibility on a department, because many departments contribute to one result.
Divisional structure: it is easy to fix responsibility for performance, because each division head answers for his product.
Step 3: (ii) Cost:
Functional structure: it is economical, as the functions are not duplicated.
Divisional structure: it is costly, as resources are duplicated in the various divisions.
Step 4: (iii) Coordination:
Functional structure: coordination is difficult for a company with many products.
Divisional structure: coordination is easy, because all the functions related to one product are brought together in a single division.
Final Answer:
Functional structure makes responsibility hard to fix, is economical and is hard to coordinate for many products. Divisional structure fixes responsibility easily, is costly and is easy to coordinate.
