It's a company, not a department.

Every company consists of different departments, working together to make stuff. Every company also has corporate goals they have set. In order to meet the corporate goals, department managers/directors need to make sure their department goals align with them. The Design Department can't have a goal that competes with the Customer Service Department's goals or there will be lost efficiency. Every team has to work together and communicate so that we aren't creating needless friction in the machine.
