What is the relationship between RRC and Rational DOORS Requirements Professional. Reading up on the product "Rational Workbench for Collaborative Lifecycle Management" one could surmise that "Rational DOORS Requirements Professional" is the next generation RRC or some integration of RRC and DOORS.

Can you provide any insight?

Our planned second product has the provisional name Rational DOORS Requirements Professional. We expect it will grow into the next-generation RequisitePro and provide Web access interoperation with other DOORS family products. We are developing it with reference to the user roles and scenarios in the multi-product Rational Workbench for Collaborative Lifecycle Management, and as is the case with Rational Team Concert and Rational Quality Manager, it can integrate with home-grown or other commercial tools that implement Open Services for Lifecycle Collaboration (OSLC) standards

We expect Rational DOORS Requirements Professional to be particularly interesting to IT development teams and quick-to-market manufacturers. It complements the market-leading DOORS requirements management products widely used by teams developing both manufactured and IT systems in teams with engineering or compliance cultures.
