Empire building is typically seen as unhealthy for a corporation, as managers will often become more concerned with acquiring greater resource control than with optimally allocating resources. Corporate controls imposed by a company's board and upper-level management are supposed to prevent empire building within a corporation's ranks. The failure to screen out empire builders can lead to corporate actions that do not necessarily provide the best growth opportunities for a corporation and its shareholders, such as acquisitions made to boost the control of the company's executives.
