OPERATIONS MANAGEMENT
Case Introduction
The Executive Shirt Company (ESC) has seen a recent dip in their profit and so they had decided to expand the company’s product line to take advantage of what he thought was a tremendous opportunity in the custom-size dress shirt market.
Mr. Dwight Collier, Gen. Manager of Executive Shirt Company (ESC) is planning to introduce customized shirts in his current production facility since they can fetch 75% more price as compared to regular shirts. Material cost for customized shirts would be about 10% higher than for standardized shirts. ESC is manufacturing 16,000 shirts per month and they plan to manufacture 2,000 customized shirts per month without hampering the current production.
The company has 5 functional divisions for making shirts:
Cutting: 1 Machine, 4 Workers
Sewing: 48 Machines, 48 Workers
Inspection: 4 workers
Ironing: 4 Machines, 4 Workers
Packaging: 4 workers
Indirect Workers (material handlers) : 4 Workers
