See the list of OpenMRS Developers
The developers for OpenMRS are not collocated. Therefore certain development practices are used to facilitate remotely working in a collaborative fashion:
Sprints are designed to be a time-boxed period of work with predetermined output. The sprints last for 2-3 weeks and all agreed upon code is meant to be completed, tested, and documented at the end of the sprint.
See Development Sprints for more information and scheduling.
The OpenMRS Development team meets daily in our IRC channel in a scrum to discuss the work at hand. The daily scrum meeting schedule can be found here.
These check-ins are separate from the sprint meetings. Developers check in weekly with their lead for 30 mins. This meeting is just to make sure that development is on task, get any followup questions asked, and a general Q&A for the developer and lead.
Communication between developers takes place mainly in public channels. The IRC channel is the first stop, followed by the developers mailing list, the weekly developer call, and then when necessary, Skype calls or Jabber/Google Talk instant messages.
