Final answer:
The disadvantage of a functional organizational structure is the lack of coordination and communication between departments, leading to inefficiency and duplication of effort.
Step-by-step explanation:
The disadvantage of a functional organizational structure is that people are in specialized 'silos' and often fail to coordinate or communicate with other departments.
This lack of coordination can result in a loss of efficiency and a duplication of effort because each division needs to acquire the same resources.
For example, in a functional organizational structure, the marketing department might create a new promotional campaign without consulting the production department, resulting in a mismatch between supply and demand.
