From what I know of Jama Connect, Micro Focus, and Inflectra, DOORS Next Generation is the number one requirement management software. There are other product options, but I believe that DOORS is the best offer out there.

My company has not evaluated Jama Connect against IBM Rational DOORS Next Generation. My company plans to evaluate Jama Connect against IBM Rational DOORS Next Generation.

We had considered other options and vendors, We decided for IBM tools because they have full stack of solutions to build them together, supported by many integrations in one ecosystem (FocalPoint, Rational QUality Manager,Radional Doors NG) and we were also using some other solutions from IBM. We want to have imeplemented a good stack from one vendor, because integrations and support is in such case usually much better. ALso from perspective of market position IBM was very high ranked at that time.

As a consultant, I was not part of the evaluation or decision making team. The solution was already in place.

I did not personally use another similar solution prior to DOORS Next Generation. However, another person in the company did use a different requirements management product.

No because this is the defacto standard in the automotive industry.
