Different companies can independently desig n and produce components, such as disk drives or operating software, and those modules will fit tog ether into a complex and smoothly functioning product because the module makers obey a g iven set of desig n rules. Modularity in manufacturing is already common in many companies. But now a number of them are beg inning to extend the approach into the desig n of their products and services. Modularity in desig n should tremendously boost the rate of innovation in many industries as it did in the computer industry. As businesses as diverse as auto manufacturing and financial services move toward modular desig ns, the authors say, competitive dynamics will chang e enormously. No long er will assemblers control the final 1 . product: suppliers of key modules will g ain leverag e and even take on responsibility for desig n rules. Companies will compete either by specifying the dominant desig n rules (as Microsoft does) or by producing excellent modules (as disk drive maker Quantum does). Leaders in a modular industry will control less, so they will have to watch the competitive environment closely for opportunities to link up with other module makers. They will also need to know more: eng ineering details that seemed trivial at the corporate level may now play a larg e part in strateg ic decisions. Leaders will also become knowledg e manag ers internally because they will need to coordinate the efforts of development g roups in order to keep them focused on the modular strateg ies the company is pursuing . In the Nineteenth century, railroads fundamentally altered the competitive landscape of business. By providing fast and cheap transportation, they forced previously protected regional companies into battles with distant rivals. The railroad companies also devised management practices to deal with their own complexity and high fixed costs that deeply influenced the second wave of industrialization at the turn of the century. Today the computer industry is in a similar leading position. Not only have computer companies transformed a wide range of markets by introducing cheap and fast information processing, but they have also led the way toward a new industry structure that makes the best use of these processing abilities. At the heart of their remarkable advance is modularity—building a complex product or process from smaller subsystems that can be 2 . designed independently yet function together as a whole. Through the widespread adoption of modular designs, the computer industry has dramatically increased its rate of innovation. Indeed, it is modularity, more than speedy processing and communication or any other technology, that is responsible for the heightened pace of change that managers in the computer industry now face. And strategies based on modularity are the best way to deal with that change. Many industries have long had a degree of modularity in their production processes. But a growing number of them are now poised to extend modularity to the design stage. Although they may have difficulty taking modularity as far as the computer industry has, managers in many industries stand to learn much about ways to employ this new approach from the experiences of their counterparts in computers. A g rowing number of industries are poised to extend modularity from the production process to the desig n stag e. A Solution to Growing Complexity The popular and business presses have made much of the awesome power of computer technology. Storage capacities and processing speeds have skyrocketed while costs have remained the same or have fallen. These improvements have depended on enormous growth in the complexity of the product. The modern computer is a bewildering array of elements working in concert, evolving rapidly in precise and elaborate ways. Modularity has enabled companies to handle this increasingly complex technology. By breaking up a 3 . product into subsystems, or modules, designers, producers, and users have gained enormous flexibility. Different companies can take responsibility for separate modules and be confident that a reliable product will arise from their collective efforts. The first modular computer, the System/360, which IBM announced in 1964, effectively illustrates this approach. The designs of previous models from IBM and other mainframe manufacturers were unique; each had its own operating system, processor, peripherals, and application software. Every time a manufacturer introduced a new computer system to take advantage of improved technology, it had to develop software and components specifically for that system while continuing to maintain those for the previous systems. When end users switched to new machines, they had to rewrite all their existing programs, and they ran the risk of losing critical data if software conversions were botched. As a result, many customers were reluctant to lease or purchase new equipment. The developers of the System/360 attacked that problem head-on. They conceived of a family of computers that would include machines of different sizes suitable for different applications, all of which would use the same instruction set and could share peripherals. To achieve this compatibility, they applied the principle of modularity in design: that is, the System/360's designers divided the designs of the processors and peripherals into visible and hidden information. IBM set up a Central Processor Control Office, which established and enforced the visible overall design rules that determined how the different modules of the machine would work together. The dozens of design teams scattered around the world had to adhere absolutely to these rules. But each team 4 . had full control over the hidden elements
