Tormigo is the competition for RaQuest in the field of requirement management. Aside from traditional entering of requirements, Tormigo enables recording data directly from MS Word and OpenOffice. In addition, Tormigo operates in Linux environments. What is more, Tormigo allows managing requirements through a system versioning them with each change. The mechanism of attributing requirements to instances of use improves the comfort and effectivenss of work of analysts and designers. Finally, I wish to emphasize that Tormigo is compatible with Enterprise Architect 9.
