Dedicated requirements management tools are available to manage product, user, system requirements for new product introduction projects.  These tools can be feature rich and very good, at least within the isolated context for which they were intended.  For example, with a dedicated requirement management tool it’s possible to define a hierarchical set of requirements starting with a product concept, through critical-to-quality user needs and down to detailed functional requirements.  Another key feature is tracking test cases and interfacing those with the tool, often it’s possible to automate the generation of traceability reports and validation protocols, whose accuracy is paramount.
