For a very long time we have been using mobicents spreadsheet
I was searching for any consistent, up-to-date roadmap information for various modules of Slee, Sip Servlets, Diameter. I do not want argue, how bad, or good this was, but I think we can agree on the fact, this approach was not bringing us a big value.
It is the time to introduce, how we deal with roadmap management for Mobicents now. First of all have a look at SipServlets roadmap and JainSLEE roadmap and check the roadmap's yourself.
Current roadmap management we use, bring us consistent, up-to-date and what is most important flexible way, how to handle roadmap. There is no need to remember, when You, as developers, deal with any of the issues, update some sheets or any extra place, to keep roadmap consistent. Only need is to manage gcode issue and roadmap is every day automatically generated and updated accordingly with the most recent changes and updates.
We can follow (observe) such roadmap every day progress or weekly progress, as you like, to check, whether the issue has been started updated or not.
When you are interested in more details, how this works you can check documentation for automated roadmap tool. (This documentation is being updated, so you may expect some progress on it).
Currently, we do have Slee and Sip Servlets modules and Diameter with Media server modules are coming soon.
check for yourself !
