"Redmine is a flexible project management web application. Written using Ruby on Rails framework, it is cross-platform and cross-database. Redmine is open source and released under the terms of the GNU General Public License v2 (GPL)."
- Is it sufficient for what project managers need? It has issues and tasks, start and end dates, assignees. It can do GANTT charts. But I don't know what other Microsoft Project-like features "real" project managers use.
- If so, did you need to add plug-ins to use it? If so, which?
- If not, what is it lacking?
I am approaching this as a technical lead of a ~3 person project who has to do some scheduling and status tracking, not as a full project manager.
EDIT 2/16/11: We are already using Redmine, so I'm interested in that solution in particular.
