You Are the Management Accountant for the West Coast Division

You are the management accountant for the West coast division of a musical instrument manufacturing company. There are three manufacturing plants in your division. Each plant manager was given decision making authority in terms of production, as long as income for their plant kept on pace. The manager at Plant A has consistently been the leader in profit for the division, but the other two managers are complaining that Plant A doesn't seem to be selling any more product than they are. The division manager has noticed higher inventory levels at Plant A, which the plant manager justifies by saying the higher levels are needed to ensure adequate sales. The division manager suspects that there could be other reasons, and she has asked you to provide three proposals for revising performance evaluation.
