The findings of an international study released by researchers from the Berkman Center for Internet & Society at Harvard Law School and the Research Center for Information Law, University of St. Gallen indicate that private-sector leadership, more so than government intervention, is the optimal method for ensuring that technologies work well together and innovation flourishes. The authors of Breaking Down Digital Barriers: When and How ICT Interoperability Drives Innovation, which was sponsored by Microsoft, found that interoperability is generally good for consumers and drives innovation, but determined that there is no "silver bullet" solution to the issue.
Interoperability has increasingly become more important because computer users -- whether they be consumers, businesses, or governments -- now tend to obtain hardware and software from different vendors and expect everything to work together. One approach to the issue that has received attention advocates government-mandated adoption of specific technologies to compel interoperability. This study suggests that such approaches are unlikely to be the optimal approach to interoperability.
"Interoperability leads to innovation and many benefits for consumers," said co-principal investigator John Palfrey, executive director of the Berkman Center for Internet & Society. "The case studies we investigated produced clear conclusions: The ICT industry is achieving considerable interoperability every day in response to the needs of customers. There is often more than one way to achieve interoperability. Market-driven initiatives tend to provide the most long-term promise."
"This research demonstrates that there is no standard application to achieve ICT interoperability," said Urs Gasser, co-principal investigator and director of the Research Center for Information Law. "Attempting to impose universal answers can produce unintended consequences such as curtailing innovation, limiting consumer choice and reducing competition. Instead, each situation needs to be analyzed on its own, to determine the best way to achieve interoperability. Nor can we forget that interoperability is simply a means to larger and more important goals, such as consumer choice, access to content, ease of use and diversity."
The research focused on three case studies in which the issues of interoperability and innovation are uppermost: digital rights management in online and offline music distribution models; various models of digital identity systems (how computing systems identify users to provide the correct level of access and security); and Web services (in which computer applications or programs connect with each other over the Internet to provide specific services to customers).
The core finding is that "increased levels of ICT interoperability generally foster innovation. But interoperability also contributes to other socially desirable outcomes. In our three case studies, we have studied its positive impact on consumer choice, ease of use, access to content, and diversity, among other things."
The investigation reached other, more nuanced conclusions:
- Interoperability does not mean the same thing in every context and as such, is not always good for everyone all the time. For example, if one wants completely secure software, then that software should probably have limited interoperability. In other words, there is no one-size-fits-all way to achieve interoperability in the ICT context.
- Interoperability can be achieved by multiple means including the licensing of intellectual property, product design, collaboration with partners, development of standards and governmental intervention. The easiest way to make a product from one company work well with a product from another company, for instance, may be for the companies to cross license their technologies. But in a different situation, another approach (collaboration or open standards) may be more effective and efficient.
- The best path to interoperability depends greatly upon context and which subsidiary goals matter most, such as prompting further innovation, providing consumer choice or ease of use, and the spurring of competition in the
