The Model-Based Approach forTransparency and a Common System Understanding

The model-based approach offers optimum transparency to achieve a common understanding of the system to be developed. Central and direct access to all networked data and measures within the product development process via a web browser enables smooth collaboration in real time.

Requirements Management in e1ns enables you to efficiently

  • capture,
  • monitor,
  • analyze and
  • manage requirements.

For a successful requirements management process, e1ns combines systematic and creative methods as required. These methods use the common database, work in a networked manner and complement each other.
