I have been with companies who tried to do it Excel-based. The tool that we currently use right now is called Polarion, it's a Siemens-based product and it's horrible.

We use Microsoft Office tools just for writing documents and Excel for some additional  information. We don't use solution supported by serious information systems.

We were not replacing any solution or tool. Instead, we are implementing a new solution to be more productive, faster, and have better visibility of what is going on with these requirements or what is related to them.

Many organizations come to DNG after using DOORS. The IBM Jazz Platform CLM integrated tool chain is a sexy idea that provides, in theory, the holy grail: planning, defect/change management, requirements, and tests, all linking together.

We used Legacy IBM Rational requirements management solution, RequisitePro.

No previous solution was used.
