Rational doors vs RRC

Hi, Can someone help me understand what are the advantages/disadvantages of RRC over Rational Doors. We are considering using Rational Doors for Requirements Management and need more information on whether we should prefer it over RRC. Thanks

I hope someone can counter what I have to say if they disagree. But reading the literature it appears that RRC is based on RequisitePro, which was a very light weight requirement management system.

RequisitePro might work for a small project that would never grow very large or have many users. But it was almost as expensive as DOORS.

Let me offer some perspective here. RRC is not based on RequisitePro. RRC is a new codebase built on the Jazz platform, which provides a bunch of useful services to applications that use it. One of the goals for RRC is to bring new capabilities to RequisitePro customers (as they have been requesting) -- that's why RRC is referred to as the "next generation RequisitePro". RRC suffers none of the technical limitations in ReqPro related to scalability (e.g. limitations in the SmallTalk virtual machine used in the ReqPro rich client).

Another goal for the RRC codebase is to provide the building blocks for DOORS Next Generation. If you follow that project on Jazz.net you will see that we are extending it to deliver capabilities that DOORS customers enjoy in DOORS 9 today as well as new ones DOORS customers are asking for.

Appears like a little bit more of the IBM dishonesty and bingo we have another Dorthy Dix.

I was advised by IBM Reps here in Australia early in 2011 that RequisitePro will be end lifed, although the IBM Product Support Life-cycle page still doesn't announce this. But given that they haven't released a Major version of ReqPro since 2008, I guess it's looking like a lame duck.

As for the planned migration\merger of DOORS & RRC on the Jazz platform - for many of us who have grown up with DOORS, it has always been a very simple tool to install and generally maintain. The Jazz platform will change all of this as it is a very complicated integration of software services, applications, middleware, whatever, that requires unique tuning to make it work in your IT environment. If anyone is familiar with the Business Objects Enterprise XI platform, you'll know what I mean.
