Chapter 1: Competing Through Development Capability

In a competitive environment that is global, intense, and dynamic, the development of new products and processes increasingly is a focal point of competition. Firms that get to market faster and more efficiently with products that are well matched to the needs and expectations of target customers create significant competitive leverage. Firms that are slow to market with products that match neither customer expectations nor the products of their rivals are destined to see their market position erode and financial performance falter. In a turbulent environment, doing product and process development well has become a requirement for being a player in the competitive game; doing development extraordinarily well has become a competitive advantage.

The New Industrial Competition: Driving Forces and Development Realities

The importance of product and process development is not limited to industries or businesses built around new scientific findings, with significant levels of R&D spending, or where new products have traditionally accounted for a major fraction of annual sales. The forces driving development are far more general. Three are particularly critical:

* Intense international competition. In business after business, the number of competitors capable of competing at a world-class level has grown at the same time that those competitors have become more aggressive. As world trade has expanded and international markets have become more accessible, the list of one's toughest competitors now includes firms that may have grown up in very different environments in North America, Europe, and Asia. The effect has been to make competition more intense, demanding, and rigorous, creating a less forgiving environment.

* Fragmented, demanding markets. Customers have grown more sophisticated and demanding. Previously unheard of levels of performance and reliability are today the expected standard. Increasing sophistication means that customers are more sensitive to nuances and differences in a product, and are attracted to products that provide solutions to their particular problems and needs. Yet they expect these solutions in easy-to-use forms.

* Diverse and rapidly changing technologies. The growing breadth and depth of technological and scientific knowledge has created new options for meeting the needs of an increasingly diverse and demanding market. The development of novel technologies and a new understanding of existing technologies increases the variety of possible solutions available to engineers and marketers in their search for new products. Furthermore, the new solutions are not only diverse, but also potentially transforming. New technologies in areas such as materials, electronics, and biology have the capacity to change fundamentally the character of a business and the nature of competition.

These forces are at work across a wide range of industries. They are central to competition in young, technically dynamic industries, but also affect mature industries where life cycles historically were relatively long, technologies mature, and demands stable. In the world auto industry, for example, the growing intensity of international competition, exploding product variety, and diversity in technology have created a turbulent environment. The number of world-scale competitors has grown from less than five in the early 1960s to more than twenty today. But perhaps more importantly, those twenty competitors come from very different environments and possess a level of capability far exceeding the standard prevailing twenty-five years ago. Much the same is true of customers. Levels of product quality once considered extraordinary are now a minimum requirement for doing business. As customers have grown more sophisticated and demanding, the variety of products has increased dramatically. In the mid 1960s, for example, the largest selling automobile in the United States was the Chevrolet Impala. The platform on which it was based sold approximately 1.5 million units per year. In 1991, the largest selling automobile in the United States was the Honda Accord, which sold about 400,000 units. Thus, in a market that is today larger than it was in 1965, the volume per model has dropped by a factor of four. Currently over 600 different automobile models are offered for sale on the U.S. market.

Similarly, technological change has had dramatic consequences. In 1970, one basic engine-drive train technology (a V8 engine, longitudinally mounted, water cooled, carbureted, hooked up to a three-speed automatic transmission with rear wheel drive) accounted for close to 80 percent of all automobile production in the United States. Indeed, there were only five engine-drive train technologies in production. By the early 1980s that number had grown to thirty-three. The growing importance of electronics, new materials, and new design concepts in engines, transmissions, suspensions, and body technologies has accelerated the pace and diversity of technological change in the 1980s. Simply keeping up with those technologies is a challenge, but an often straightforward one in comparison with having to integrate them in development efforts.

Similar forces have been at work in other traditional, mature industries. In textiles and apparel, for example, firms such as Benetton and The Limited have used information technology to create a production and distribution network which links retail outlets directly to distribution centers and back into factories and suppliers in the chain of production from fiber to finished product. The thrust of these networks is the ability to respond quickly to changing customer demands at relatively low cost. Fueled in part by availability and in part by growing demands for differentiated products, product variety has expanded significantly. In plant after plant, one finds vast increases in the number of styles produced and a sharp decline in the length of production runs. These are not changes of 10 or 20 percent; in the 1980s, it was common for apparel plants to experience a four- to fivefold increase in the number of styles produced. These increases in garment variety have pushed back into the textile plants as well. For example, the average lot size for dying at Greenwood Mills, a U.S. textile firm, declined in the 1980s from 120,000 to 11,000 yards.

Changes in markets and technologies for automobile and textile firms have accentuated the importance of speed and variety in product development. But changes in competition, customer demand, and technology have also had dramatic effects on newer, less mature industries in which product innovation has always been an important part of competition. In industries such as computer disk drives and medical equipment, already short life cycles have shrunk further and product variety has increased. In addition, competition has placed increased pressure on product reliability and product cost. In disk drives, for example, the market for Winchester-technology hard disks has expanded from a base in high-end systems for mainframe computers to include a spectrum of applications ranging from notebook personal computers to large-scale supercomputers. Even within an application segment, the number of sizes, capacities, access times, and features has increased sharply. In addition to this explosion of variety, firms in the hard disk drive industry have had to meet demands for dramatic increases in reliability (tenfold in five years) and decreases in cost (5 percent to 8 percent quarterly). These have been met in part by incremental improvements in established technologies and in part through the introduction of new design concepts, production technologies, materials, and software.

Much the same has been true in the market for new medical...
