Williams Instruments manufactures specialized surgical equipment for hospitals and clinics throughout the world. One of Williams' most popular products, comprising 40% of its revenues and 35% of its profits, is a blood pressure measuring device. Average production and sales are 400 units per month. Williams has achieved its success in the market through excellent customer service and product reliability. The manufacturing process consists primarily of assembly of components purchased from various electronic firms, plus a small amount of metalworking and finishing. The manufacturing operations cost $600 per unit. The purchased parts cost Williams $800, of which $300 is for parts which Williams could manufacture in Its existing facility for $100 in materials for each unit, plus an investment in labor and equipment which would cost $175,000 per month. Also, Williams is considering outsourcing to another firm, Matrix Concepts, Inc., the marketing, distribution, and servicing for its units. This would save Williams $75,000 in monthly materials and labor costs. The cost of the contract would be $125 per product.
