Reviews from Real Users

Hubert Zenner, Technical Sales Specialist at a computer software company, says that "IBM Rational DOORS Next Generation is easier to expand to build a backend with several servers, so you can also use it to scale up to several hundreds of users without major problems."

Kapil Raikar, Senior Manager – Development, PD and Data Virtulization at a computer software company, states that "There are many good features with DOORS. The solution has a concept of streams and baselines, as well as a concept of components. A component is a subproject inside a project."
