Which type of layout features departments or other functional groupings in which similar activities are performed

Process-oriented.

Explanation:

A functional (departmental) organizational structure is a type of structure used to organize staffs by dividing them into various departments based on their skill set, roles or functions and knowledge.

These departments which are vertically structured may include, finance, IT, sales and marketing, research and development, customer service etc. Also, the various departments are headed by a functional manager who are saddled with the responsibility of overseeing, managing and reporting to the executive management.

Similarly, a type of layout in the manufacturing process that features departments or other functional groupings in which similar activities are performed is generally referred to as being process-oriented.

One of the main advantages of a process-oriented layout is that it mitigates or reduces difficulties associated with material flow variability for a product.
