Achieving Full-Cycle Cost Management

Companies tend to assume that a large percentage of a product’s costs are locked in by design — that little can be done to reduce costs once the design is set. This belief has shaped many cost-management programs across diverse products’ life cycles. Because of it, firms will often focus on cost reduction during the design phase and cost containment during manufacturing. But are much of a product’s costs truly locked in during design?

To answer that, we studied the consumer-products division of Olympus Optical Co. Ltd. in Tokyo, Japan. In-depth field observations of the life cycle of the new Stylus Zoom camera helped provide a detailed understanding of how the company applies various cost-management techniques across a product’s life cycle. (See “About the Research.”) In particular, we investigated the level of costs that are designed in because that shapes the way a company manages costs across the product life cycle. If a significant portion of costs is designed in, we would expect to observe aggressive cost management predominantly in the design (and not the manufacturing) phase of the life cycle.
