Modularization is the problem, notthe solution.
One great advance in production systems was the ‘modularization’ of product components so that each component could be designed and produced separately and then assembled. This notion is well over a century old. A second advance was in farming out the components to subcontractors. While this is quite old as well, it matured into what we have today only about 25 years ago.
Dividing the product into components supplied by others has two profound effects.
- Capital investment and associated risks are distributed out of the central enterprise. The effect of this cannot be understated; each supplier has to go get their own capital.
- Every supplier’s place in the enterprise is conditional based on a variety of competitive factors. This introduction of market forces into the equation is huge; in theory, every cycle thousands of companies are trying to innovate their way into hundreds of enterprise slots. So if the prime contractor has a good way of communicating value, many innovative solutions should emerge.
In practice, the enterprise has yet to fully benefit from competitive innovation and decentralized financing from this modularization. The capital financing system is decentralized but the reward system and metrics stay centralized. For example, a steering wheel supplier like ZF TRW hadsto build its production line for Ford, and hope that Ford’s cars are successful. TRW has minute control over that success and the lenders factor this in. Japanese keiretsu get around these extra capital costs by keeping the supply chain constellation and funding stable; the same investors ‘own’ Toyota and their steering wheel supplier. This also makes process integration far easier. But innovation is effectively killed.
Apple uses their capital power to fund innovation in competitive suppliers, giving huge benefits especially in materials processing and fabrication where process and equipment are tightly linked. But this is very tricky, being the funder but forcing the supplier to innovate on their own. We got some insight into this with the collapse of their sapphire film supplier.
Types of Modularization
When we think of modularization, we have several notions:
The product itself is divided into parts. An old style PeeCee was an extreme example of this. End users could literally buy components from absolutely discrete categories and put them together themselves, and could then over the life of the device insert upgraded components at will. Military aircraft are another extreme example. One reason is that the whole system is just too complicated to manage, so breaking the aircraft into components puts constraints on the dynamism of the product and process features. This ensures that the aircraft will be poorly optimized, many have concluded. (Another reason for dividing up complex military systems is that many of these systems are so profoundly expensive that to get them funded requires having components made in key Congressional districts, bringing ‘jobs.’)
The process workers are divided into companies and teams. This is usual. Different companies are arranged in a ‘supply chain’ to provide discrete parts and services. These are assembled on the way to shipping to a customer. We’ve already mentioned the potential but unrealized advantages of involving market forces and distributing capital risk.
The enterprise functions are modularized. This is quite a bit more prevalent today than in the past as specialized abstractions and computerized tools are adopted. For example strategic planners live in a different infrastructure and culture than, say, the manufacturing engineers and operations managers. Typical divisions include financial, sales, strategy, marketing, design, legal and production. The rationale is that each is essential and expected to play their role well. The divisions have hard boundaries.
Capital investment is modular. In general, money is attracted either by discrete project or discrete vehicle. An example of the former is money borrowed to finance a factory. The latter is more complex because various intermediaries can be involved because of value-sucking holes in the law. Thus, it is advantageous for a company to borrow money to buy a commercial aircraft and lease it for the life of the plane to a carrier. Another example is how loans may be bundled so that many investors are investing in many projects. This mitigates their risk but creates a long, inefficient pipeline of value monitoring. Notwithstanding, where the money touches the enterprise, there is someone fencing capital to production.
Each of these four penetrate the way things are done today, whether in manufacturing, military operations, health care, education or disaster response.
Congruence of Modularity
In today’s environment, much of this modularization is congruent, for example the breakdown of the product corresponds exactly in most cases with the breakdown in process groups (as suppliers) and an many cases, the modularization of capital. Financing internally is effectively modular and linked to process components. With the popularization of activity based costing, financing can be as fine grained as the analysts wish.
In each case and especially in cases where the modularization continues over categories, the enterprise and what it can do is constrained.
This is bad. Any dimension of the enterprise has less intrinsic agility. It also has structural inefficiencies, in part because it has to maintain so many ontologically distinct functions in each of the entities, and worry about how they interface. Modules mean interfaces.
There cannot be a global story that everyone understands and how they can add value to the story. These inefficiencies are very serious. We looked at military systems for example (because we could) and the numbers are astonishing.
An ideal would be a situation where enterprise strategists could decide when and where to have boundaries so as to pick the tradeoffs. And then once things got going, the strategist or manager or collaborative could shift, soften and harden these boundaries as they learned more about what they are doing.
