I was at UK IBM Innovate last week and one very interesting presentation was from Jeremy Dick of Integrate. Jeremy highlighted some of the key differences between DOORS Classic and DOORS Next Generation. I will draw from that discussion here, but also add my own commentary.
There is a learning circle on IBM developerWorks on the topic of DOORS Next Generation. This is built on the ideas presented in our paper.
I have been working with the DOORS requirements management tool for well over 10 years now, starting with version 4. DOORS is still going strong and is now up at version 9.
