Achieving Full-Cycle Cost Management

Contrary to a widely held assumption, companies can integrate a variety of techniques to substantially reduce costs, not just in the design phase but throughout the product life cycle.

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,” p. 46) 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.

Instead, we found that Olympus Optical achieves significant cost reductions in manufacturing, contradicting the widely held assumption that a large percentage of costs are locked in during design. Indeed, our research demonstrates that costs can be aggressively managed throughout the product life cycle. Furthermore, we found that Olympus Optical applies various cost-management techniques in an integrated manner, with the outputs of some techniques acting as inputs to others, thereby increasing the program’s overall effectiveness. Our observations suggest that companies competing aggressively on cost might consider the adoption of some form of an integrated cost-management program that spans the entire product life cycle.

Five Techniques

A commonly quoted statistic is that 80% to 95% of the cost of a product is determined by its design and is therefore set before the item enters manufacturing.1 That assumption has been used to... To read the complete article, login or sign-up using the form below.
