Ultimately, the health of an open source project is measured by the production of useful code, and the broad adoption of that code.  This is easy to spot in many examples, projects like the Linux Kernel, Apache Tomcat, Samba, GNU gcc, etc are so useful, and have become so broadly adopted that they are literally the milieu in which the modern world is embedded.

It’s easy to spot the successes.  And it’s also easy to notice that there are thriving communities collaborating around such successes.  It’s much more interesting to ask what contributes to successful open source communities.

I would maintain, that successful open source communities lower the barriers to useful participation.  They lower the activation energy for innovative activity.  Some of the ways they do this are rather obvious, and some are less so.

Technical Barriers to participation:

Social Barriers to participation:

Legal Barriers to participation:

Evaluating Community Health:

The higher the barriers to collaboration a community raises, the harder it is for it to become successful.  When starting an open source project, or evaluating whether to consume or contribute to one, it can be helpful to consider the barriers to participation, as early indicators of whether or not the project is likely to become or remain successful.

What other barriers to participation do you feel are important to be kept low for open source success?

  1. Hi, Ed.

    What do you think about barriers specific to nontechnical contributors?

    For example, if someone lacks programming skill (as I do ;) but wants to give back to a project, what challenges might they face? I’ve seen a lot of people give back in the area of testing, documentation writing and translation, and these are often areas that could use a little more attention…

    Is it as simple as posting a “help wanted” page with items workable by people with varying skills?

  2. Tim, a lot of the barriers to non-technical contributors often have to do with under appreciation of what they have to contribute. Testing matters rather a lot. Good documentation is very valuable (I even did a bit of that in addition to contributing code back in the day for Wireshark, when it was still called Ethereal). It helps a lot to have both an on ramp for such contributions and to value them.

    They also serve, who do not write code.
