Nothing captures Japanese offshoring practices better than the old Japanese proverb "Tap the stone bridge before crossing." As global IT offshoring continues to grow at an astounding pace,3 the seemingly impenetrable Japanese market baffles many offshore IT vendors. On one hand, Japanese industries are among the most software-intensive, yet they appear reluctant when it comes to offshoring. In this article, we offer six paradoxical insights from field research involving five leading Japanese companiesToshiba, Fujitsu, IBM-Japan, Hitachi, and Mitsubishiand their offshore IT vendors spanning China, Vietnam, Philippines, India, Hungary, Romania, Bulgaria, Belarus, Russia, Taiwan, and Sweden to uncover insightful peculiarities in Japanese offshoring practices (see the sidebar "How the Study was Conducted").

Some of the findings might come as a surprise to managers who are more accustomed to Westernparticularly Americanoffshoring practices (see Figure 1). Overall, our research lends novel insights into how the Japanese have a different interpretation of what constitutes outsourcing, how their offshoring decisions are driven by knowledge rather than cost or value drivers, their use of circles of trust with a high entry threshold, unusual but surprisingly effective governance strategies, and how they have mastered the sophisticated art of modularization. These paradoxical practices offer invaluable lessons for both Western companies that outsource IT as well as for offshore vendors attempting to gain a foothold in the burgeoning japanese market.

A Broader Field of View

The widespread misperception that Japanese firms do not extensively outsource IT is rooted in the fundamental differences in meaning of outsourcing in Japanese versus Western interpretations (see Figure 2). The Japanese have outsourced software development for much longer than comparable American firms but their IT offshoring history is brief in comparison.4 The most prevalent form of outsourcing in Japan is to direct subsidiaries (i.e., the client fully owns the vendor organization), followed by an increasingly popular affiliate model where the client has a direct financial stake in the vendor. These models are rarely encountered in Western companies, where most outsourcing follows the third and least popular model among Japanese organizationsa third-party vendor bound by a contract.3 The logic is that the first two models minimize conflicts of interests between clients and vendorsor what economists call agency conflicts. In turn, outsourcing relationships are more likely to be a win-win situation for both the client and vendor and contracts more extensive than a handshake are rarely necessary.

The intellectual property-driven and quality-driven nature of the Japanese consumer electronics businessnot just cultural normscreate a strong disinclination among these companies to rely on formal or complete contracts (discussed later). The myth that IT outsourcing is less prevalent in Japanese companies holds only for outsourcing to third party offshore vendors (Type C in Figure 2), from where most foreign vendors' anecdotes about closed doors appear to stem. A widespread corporate practice is to consciously manage the first twoand increasingly all threetypes of outsourced projects as a balanced portfolio. Japanese managers are however becoming progressively more open to this model, albeit with some puzzling but surprisingly effective practices described next.

Trust But Verify

We found that IT offshoring decisions of Japanese companiesespecially those that involve third-party vendorsare overwhelmingly motivated by access to unique technical expertise rather than by cost-cutting considerations. Japanese managers consistently cautioned us that they only consider offshoring to third-party vendors when the required technical expertise is unavailable in subsidiary or affiliate companies. Western offshoring, in contrast, is motivated primarily by value and cost. This should come as little surprise considering much of the early practices of knowledge management came from corporate Japan.8 The prized asset in such rare outsourcing partnerships is the offshore vendor's specialized knowledge. Unfortunately, it is hazardous to trust and almost impossible to verify a vendor's technical expertise upfront.11 Knowledge differences between the client and the offshore vendor therefore expose the client to the risk of being taken advantage of. A peculiar Japanese solution to this dilemma is to invest heavily in verifying the technical expertise of multiple vendors using "dummy projects," evaluating the process and outcomes, and then blindly trusting the chosen one on the next project.

One company in our study did this by reverse-generating project requirements for an internally completed project, deliberately introducing ambiguities into the requirements, and giving duplicate development contracts to three different vendors in parallel (see Sidebar "A Tale of Three Vendors"). None of the vendors were aware that the same project was also being developed by the others or that the client already had a completed solution. Internal IT staff evaluated the technical quality of the completed solutions from each of the three vendors using the existing internal software source code from the completed software as a benchmark. In addition to the quality of the delivered code, the company also assigned weight to whether (and how) each vendor sought clarifications for the intentionally-ambiguous requirements or whether they just assumed them away. The highest ranked vendorneither the lowest in cost nor the highest in technical qualitymade it to the preferred partner list and got the contract for the actual project that itself was worth about $100,000.

Due diligence and vendor screening are much talked about in American corporate circles but this peculiar Japanese practice gives the idea its teeth. Many Western managers unaccustomed to Japanese business practices will undoubtedly scoff at the idea of spending $100,000 just to select the "right" vendor for a $100,000 project. But offshore vendors must realize that most Japanese managers view this as the beginning of a long-term relationship and not a contracting cost. Japanese companies rely heavily on informal contracting within such circles of trust. Neither the most technically adept nor the lowest-cost vendors have any particular advantages in joining those circles.

Small Pieces, Loosely Joined

Many Japanese managers are cautious that offshoring can expose core technologies and business processes to offshore vendors, creating a potential risk of intellectual property theft. This is a legitimate concern, given that the Chinese vendors used by Honda started selling their own replicas of its motorcycles, GM suppliers cloned an entire car, and a Chinese manufacturer replicated Hitachi's 1.8" microdrive used in the original iPod.1 Since almost the entire software offshoring market consists of Japanese hardware and consumer electronics manufacturers (there are a few pure-play software development companies in Japan), this concern is more the norm than an exception. Theft of intellectual property is notoriously difficult to detect in intangible products such as software compared to manufactured goods. Moreover, since the majority of Japanese offshoring is motivated by knowledge differences between the client and vendor, the likelihood that the vendor has unique technical expertise is high but so is the likelihood that the vendor does not havebut might valuethe client's business domain knowledge.

Leading Japanese companies consistently follow a simple but surprisingly effective tactic to proactively mitigate this risk: They decompose an outsourced project into smaller pieces that are outsourced to different vendors in a way that only the client can piece them back together. In technical terms, they protect their proprietary knowledge assets through their mastery of the art of modularization.9 This approach allows keeping core technologies in-house and also distributes project risk. In contrast, most Western companies attempt to safeguard themselves against this risk through legal contracts, which are frequently unenforceable across national boundaries and in the vendors' countries.

Control through Design

We also found that Japanese companies exercise control over the vendor by completely controlling the front-end design rather than using the Western-style strategy of attempting to control the development process or methodology used by the vendor. This approach requires the complete conceptual and architectural design of the outsourced project to be done in-house by the client, which significantly increases the cost of offshoring. In contrast, vendor involvement in the early stages is more common outside Japan. Figure 3 illustrates how the hand-off to the vendor typically occurs much later in the Japanese approach than in the typical American model.

One motivation for doing this in the Japanese companies that we studied stems from the type of software that is outsourced. Unlike the majority of Western companies where the largest chunk of offshoring is for business software applications, these Japanese companies primarily outsourced embedded software (e.g., software code that functions inside a piece of hardware such as a cell phone, laser printer, GPS car navigation system, or a digital camera). The success of such hardware is inextricably tied to the quality and reliability of such embedded software. The second motivation is the strong desire to protect proprietary knowledge by keeping business domain knowledge separate from technical knowledge. Controlling the design and Core technology allows Japanese companies to effectively accomplish this without compromising the user interface or functionality of the outsourced project. This also drives the use of "Bridge Software Engineers" discussed later. Third, this strategy allows Japanese engineers to overcome language barriers because the hand-offs to the vendor are language-independent standardized design notations (such as Unified modeling language (UML) diagrams, user interface mock-ups, and flow charts).

The added investment in control through in-house design pays off in the form of a more on-target end result and a lowered need to monitor how the vendor internally manages the development process. Much like their American competitors, extensive use of clearly specified outcome metrics (which are rigorously evaluated by Japanese engineers during acceptance tests in the testing and delivery phases of the outsourced project) is widespread.

Mastering the Art of Synchronized Swimming

The concept of requirements "signoff"widely used in Western-style offshoringis a rare practice in Japanese offshoring partnerships. Japanese companies expect requirements to be volatile and constantly evolve over the lifecycle of an outsourced project. A leading, $2 Billion Indian IT vendor in our study complained that this process difference was the singly most challenging aspect of working with Japanese clients. Since the majority of projects are embedded software or middleware applicationsrather than business applications that are more commonly outsourced outside Japanthe performance of the electronics hardware in which the software is embedded is inextricably tied to the quality of this software. Japanese companies have also been very successful in their use of concurrent engineering, where the hardware and software are developed in parallel to shorten time-to-market.8 We observed a strong reluctance to discard this well-honed practice. Therefore, design changes during the development of the hardware often trigger necessary changes in the design of the accompanying software, generating volatility in the requirements of the outsourced software components. This requires a vendor to synchronize its internal development process with the other pieces of the total system that are being concurrently developed inside the Japanese client organization. Freezing of requirements at the outset of a project is rarely feasible. The most successful foreign vendors so far have been ones that have come to accept requirements volatility as a given rather than trying to fight it.

Bridges, Not Analysts

Another striking difference in Japanese offshoring relationships is the use of what is described as a "Bridge Software Engineer" (BSE). The concept of a BSE does not have a precise equivalent in most Western organizations, although it resembles a systems analyst or client liaison on the surface. Unlike systems analysts that play an active role in a project during its front-end phases,5 the BSE actively and constantly coordinates knowledge flows between the client and vendor groups throughout the entire project lifecyclea key ingredient in software projects.2,6,10 A typical BSE is usually assigned full time to no more than two projects. The BSE is a mid-level manager from either the client company or in the case of third-party outsourcing partnerships, drawn from a subsidiary or affiliate company in the vendor's country. A BSE can reside at the vendor's site, the company's site, or split time between the two.

The role of a BSE is to maintain the separation of the company's proprietary business domain knowledge from the vendor's technical knowledge while ensuring that the two are effectively integrated into the offshore development process. In the projects in our study, the BSEoften bilingualwas the primary channel of communication between the client and vendor. (As an aside, we found that weekly video conferencing is the preferred and most heavily used mode of communication between client and vendor staff.) Japanese managers firmly believe that constant communication is the key factor determining the fate of an outsourced project. The BSE also ensures that stakeholders in the client organization are in agreement about the progress and direction of the work, consistent with the strong emphasis on group consensusrather than Western-style individualismin Japanese companies. A BSE therefore serves as a knowledge broker for the contextual business idiosyncrasies and the associated cultural subtleties of the outsourced project. A BSE also serves as a hedge against project risk in lieu of the precisely spelled out contracts in Western-style offshoring partnerships.

Conclusion: Perspective Matters

Offshore vendors intent on winning business in the Japanese offshoring market must remember that they are not in Kansas anymore. Three idiosyncrasies of the Japanese market are noteworthy. First, unlike value-motivated offshoring by Western companies, Japanese offshoring to outside vendors is primarily for access to expertise that is unavailable in subsidiary or affiliate companies. They will go to surprisingly great lengths to verify vendors' technical expertise. The vendors that pass their litmus tests are usually governed through informal, trust-based relationships rather than formal Western-style contracts. Second, volatile project requirements are the norm and are rooted in the extensive use of concurrent engineering practices that have historically worked well in Japanese companies. Finally, Japanese companies prefer to completely control the design and core technologies of off-shored projects and often deploy a BSE to coordinate knowledge integration between the client and vendor staff.

Japanese offshoring practices also lend three valuable insights for Western companies that offshore. First, capital-based relationships with offshore vendors can trounce some of the oft-encountered agency problems and governance challenges. Second, modularization of projects by breaking them up into pieces offshored to different vendors in a way that they collectively cannot put together can protect intellectual property and distribute risk for some types of projects better than legal contracts. This is less feasible with business applications than it is with embedded software. Third, they should consider bringing more of the high-level design back in-house as an alternative to other types of project controls such as output specifications or mandating specific development processes.
