Agile vs. Open
I've been asked multiple times why open source project management does not fully adopt agile methodologies, which are so great. Or what are the main differences between the two.
Agile is good for you
So first of all, I'd like to say that I think Agile methodologies are great. Their primary value to me is to allow software development groups to handle their stakeholders requirements in a sane way. By involving developers more in the center of game, they contribute to use Autonomy (one of the three main intrinsic motivators that Dan Pink mentions in his book Drive) as a way to maximize a development team productivity.
Agile vs. Open
That said, applying pure Agile methods doesn't really work well for open source project management. Some great concepts can be reused, like frequent time-based releases, peer review, or test-driven development. But most of the group tools assume a local, relatively small team. Doing a morning stand-up meeting with a team of 60 in widely different timezones is a bit difficult. It also assumes that project management has some direct control over the developers (they can pick in the backlog, but not outside), while there is no such thing in an open development project.
The goals are also different. The main goal of Agile in my opinion is to maximize a development team productivity. Optimizing the team velocity so that the most can be achieved by a given-size team. The main goal of Open source project management is not to maximize productivity. It's to maximize contributions. Produce the most, with the largest group of people possible.
That's why open source project management is all about setting the framework and the rules of play (what can get in trunk and how), and about trying to keep track of what is being done (to minimize confusion and friction between groups of developers). That's why our release cycles are slightly longer than Agile sprints, to have a cadence that is more inclusive of development styles, and to enforce time to focus, as a group, on QA before a release.
Agile devs in Open source
It's difficult for Agile developers to abandon their nice tools and adopt seemingly-more-confusing open source bazaar ways. But in the end, I think open source is more empowering, by addressing the two other Dan Pink types of intrinsic motivators, Purpose and Mastery. Working on an open source project and contributing to the world's amount of public knowledge obviously gives an individual a sense of purpose to his work, but even more important is mastery.
Each developer in an open source project actually represents himself. With all proceedings and production being public, in the end his personal name is attached to it. He builds mastery and influence over the project by his own actions, not by the name of the company that pays his bills. Of course his employer has requirements and usually pays him to work on something specific, but the developer acts as the gateway to get his employer's requirements into the open source project. That way of handling stakeholders requirements places individual developers at the very center of the game, even more than Agile does. You end up with the highest number of highly-motivated individuals, which in turn leads to lots of stuff getting done.
Finally, nothing prevents an open source project to have Agile development subgroups contributing to it. These subgroups can have user stories, planning poker, feature backlogs, pair programming and stand-up meetings. There are multiple challenges though. Aligning agile sprints with the open source project's common development schedule is tricky. The Agile work schedule needs to be adapted to make room for generic open source project tasks like random code reviews or pre-release QA. Some other group may end up implementing a feature from your internal backlog, and communicating the backlog outside the group can be bothersome and challenging.
I'd like to find ways, though. What do you think ? Can Agile and Open live in harmony ? Should they try ?
