Interoperability and Innovation

Most software professionals already know about the important role interoperability plays in fostering innovation. In a recent commentary in Financial Times ("Interoperability: the great enabler"), Michael Schrage, a researcher with the MIT's Sloan School of Management notes

Barriers to interdisciplinary innovation tumble. Favourable economics of interoperable innovation will tempt ambitious "inter-preneurs" to test their ideas.

How might interoperability between Siemens cochlear implants, Apple iPhones, Nike running shoes accelerometers, LG microwave ovens, Nintendo Wiis and BMW Series 3 Sedans create bold entrepreneurial, or diversification, opportunities? Who knows? But the fact that the question piques curiosity reveals fundamental changes in the global innovation climate.

A new innovator's dilemma begins to attend the extent of interoperability in products.

Golden Rules for Contribution-based Communities

There are some basic, golden rules when it comes to having a vibrant community of contributors.

The following are rules I have extracted and learned based on my experience managing and working with engineers actively involved and participating in the Apache/Derby, PostgreSQL and MySQL open-source communities. These rules are also based on extensive discussions with many folks involved with the MySQL community, with the PostgreSQL community and with the Apache/Derby (Java DB) community, over many years.

Before I go through these rules, I would like to thank Marten Mickos for having suggested some of the headings for these rules. (I originally had much longer headings for all of them.) I would also like to thank many of MySQL, PostgreSQL and Java DB colleagues, as well as to many other colleagues involved in open-source development, for having contributed to the ideas and practices behind these rules.

A) Transparency.
1.Often, this openness can span all the way from development (architectural specification, implementation design and planning, implementation, code review and walk-through) to testing, qualification and release.
2.It may be possible to move towards greater transparency over time but openness in development is often the minimum starting point. 

B) Dialog.
1.It should be possible to conduct open dialog and conversation regarding any aspect of the development (and other aspects of) work.
2.When mailing lists and other archive-able communication channels (such as wikis) focused on development work are opened up, it becomes easier to conduct open dialog and conversation regarding the development work. 
3.Of course, when a corporation or business concern contributes (either as a major contributor or a minor contributor) to the development of an open-source product, it is to be expected that some aspects of the development work (e.g. those related to specific customer needs) may remain obscure through mechanisms such as withholding of a customer's name. 

C) Pace.
1.It should be possible to track the fate of any contribution and have a public archive of the conversation conducted regarding that contribution—recording decisions made and various feedback loops in time for the purposes of learning and further work.
2.For this purpose, it is often sufficient to have a time record of the conversation conducted with respect to the given contribution.
3.These records can be searched to determine the fate of the contribution.
4.These records help provide a learning platform for the future contributors.

D) Setting Expectations.
1.Using available and open information, the contributor community should be able to form and entertain valid expectations regarding milestones, releases, timelines, etc.
2.Anticipating the future and related risk management helps all market participants to reduce transaction costs.

E) Small is Beautiful.
1.While it should be possible to absorb contribution of any size, emphasis should be put on  absorbing smaller and incremental contributions.
2.To create mass and momentum and community and quality, it helps to encourage smaller contributions.

F) Differences.
1.Not all contributions are equal.
Contributions are judged by whether they are well designed, fit into business roadmaps, are well documented, comply with standards, do not produce regressions in the code and improve performance.
2.Not all contributors are equal.
Contributors vary in expertise, skill and experience.
These variations give meaning to the practices and procedures of the contributor community.

G) Places.
1.It is clear where one needs to work.
There are enough branches or trees to serve distinctly different target groups.
2.Trees and branches are well-groomed.
Active code branches or trees are kept at a minimum set in order to keep the product roadmap and expectations coherent.

H) Parallelism.
1.Contributions are added in parallel with frequent synchronization so that community participants can respond to each others' work.Parallel work leads—naturally and out of brute necessity—to modularization, better and faster integration.

I) Incrementalism.
1.Work is conducted in increments.
2.Each contribution does one thing.
3.Each contribution has a test case that exercises it.

J) Learning.
1.Contributor community assets (channels of communications, forums, bug databases, etc.) are developed to improve learning by all participants and contributors.

Innovation Logic

Marten Mickos discusses the logic of open-source innovation and business in an interview conducted by Josh Hyatt, contributing editor of MIT Sloan Management Review.

The interview, originally conducted for the Business Insight Journal Report, has been published by The Wall Street Journal: "Software Firm is Open for Innovation".

I like the salient point with which Marten ends the interview:

Even if I showed you my DNA, you wouldn't know how to become me.

Systems: Exploration vs. Exploitation

When it comes to learning, systems and resources, James March has summarized it all:

Maintaining an appropriate balance between exploration and exploitation is a primary factor in system survival and prosperity.
