Requirements are developed, refined, implemented and tested over several phases, corresponding to the phases in the life cycle model (or V-model) presented in the CENELEC standards EN 50126, EN 50128 and EN 50129. Traceability of requirements is an important part of requirements management. Particularly when refining the requirements, new insights are often added that can have an impact on the requirements at a higher level. A functioning change management system for traceability is therefore very important.
Requirements management is usually tool-based, as this is the only way to reliably keep track of requirements over several project phases through to the test specifications. Enotrac supports customers in requirements management on site or with appropriate RE tools. The Enotrac experts have experience with all common RE tools; the customer is free to choose the system that is suitable for them.
