Several roles are concerned with requirements quality. Of course, there is the requirements author, writing the requirements. But there is also the reviewer, who proof-reads and validates the requirements. And finally, there is the QA-Engineer, responsible for the overall quality of all artifacts created during the engineering process. Each of these roles needs a different view on requirements and different tools in order to do their work efficiently and achieve a high requirements quality. In this article I am going to show you how the Qualicen products specifically support authors, reviewers and QA-engineers in their work to keep requirements quality high.
