What is a control implication for an organization that adopts a flat structure?

Flat structures reduce hierarchical layers, increasing spans of control. With fewer supervisors overseeing more employees, the time and ability for supervision becomes limited, which is a control weakness.

Option A refers to innovation, not control implications.

Options C and D describe hierarchical or vertical structures, not flat ones.

Thus, the control implication of a flat structure is limited supervision availability (Option B).
