The main players seem to be:
When I first used VersionOne back, I guess about 2004, I thought it was great. But last year (2012) I was on a team using it and it was ... hmmm ... good but not exciting. It offered a very rich feature set, but it seemed to me to have lost focus on useable features. I remember several years ago a projects page that showed an estimated time of delivery. To me, kinda fundamental. Not really available in the current version.
- Free for small teams/use with limited features ... very restrictive.
- Large range of features.
- Multiple projects
- Actual effort reporting independent of iteration.
- Great customisation.
- Track lifecyle of user wish list right through to tasks.
- Support for automated release documentation.
- Forget hosting if your not in the US of A. The product does not support time zones and does not update burn down until the end of the day which for me is in the middle of the day ... if your trying to promote team acceptance this is a red flag. (I reported this as an issue several years ago and I know it was also reported in 2012.)
- Hosted options are very very slow.
- No retrospective time entry, which is greatly aggravated by the time zone problem. You cannot enter what you did yesterday.
After a few months of using it ... I'm not impressed. It provides a web view and a Java application. The two seem to written by different teams. While the web view allows entry of today's effort and updating of "to do" (velocity), the Java application allows editing the original estimate but not the "to do".
The Java application just does not cut the Scrum intent. I cannot see how a team can manage "burn down" using it.
- Retrospective time entry (enter effort tomorrow).
- Different views (Java app / web) have different models.
Simple, but in the end Excel would be better.
Dunno, but I think Excel has more to offer.
I summary, today, I would consider other options than VersionOne or Scrumworks. But VersionOne is way better that Scrumworks. Actually, Scrumworks seems to me to be more of an inhibitor than useful :-(.
