Hi Martin, here's my reply as well. Please see my answers below.

Yes and no. Sure, most full-time XWiki developers are paid by XWiki SAS, but it's also because the company went to hire active community members. There are also some former employees who are still contributors although no longer employed by XWiki SAS. > What are the costs and benefits of using open source development methods > in this > situation?

All of those factors play a role. Some customers pay for the development of very specific features or extensions. For instance, the Office document Import feature was paid for by a client. There is an internal roadmap process at XWiki SAS where stakeholders from every department can voice their priorities (sysadmin, dev, project management, sales, marketing, research...). Once this has been done, a roadmap is proposed, that members of the Open-Source community can add to if they wish. In addition to this, about 40-50% of the time of core developers is preserved so that they work on maintenance and bug fixing tasks, which they choose what to spend on. > Is there a special time in the release cycle when new content is agreed > upon?

There is a new large release every year, interspersed by major releases every 2-3 months. There is a roadmap meeting for each of those, thus it's easy to gather feedback and make priorities evolve along the way. For a large release, a theme and a sub-theme are agreed on that set the general direction of that release. For major releases, a list of JIRA tasks is agreed on.

Open-Source users tests parts of the software not tested by the QA team, and vice-versa. Both methods complement each other. > Could automated testing stand on its with sufficient coverage? No. Some things cannot be tested automatically, especially on the look & feel side. > On a similar note, how do the different > methods pursued in customer support (like detailed documentation, > peers helping each other, and specialized paid support) interact and > draw upon each other? > Documentation is updated based on the most frequent requests from customers. Paid support users are usually different from mailing list users, although some of the latter do convert to the former from time to time.
