Final answer:
The company is most likely departmentalized by function, grouping employees based on the functions they perform.
Step-by-step explanation:
The company is most likely departmentalized by function.
The managers prefer to group employees doing the same activity, which suggests that the company uses a functional departmentalization structure.
In this structure, employees are grouped by the functions they perform, such as marketing, operations, finance, and so on.
While this simplifies supervision and allows for specialization in specific areas, it can slow decision making and lead to employees prioritizing the needs of their own departments over the overall goals of the company.
