Answer:
e. Matrix mode of Departmentalization
Step-by-step explanation:
The matrix mode of departmentalization seeks to bring a combination the best features of both the task force (product or project) as well as the functional departmentalization modes with the aim of improving the cooperation among several components that are required for a particular activity in the organisation.
The aim is to organize the departments in the organisation based on a particular project or product line as well as around functional lines. This ensures that the advantages of the two modes can be combined.
The matrix departmentalization mode puts each department on the same line as described in the question and since no department has an hierarchy over the other but are horizontally lined, it is expected that they can work better with one another. However, due to the lack of a clear hierarchical system of chain of order there could be uncertainty when defining the reporting chain.
