The Avenqo Project Engineering Platform bases on the Knowledge Entities concept. Under the title "Traceable Knowledge by enhancing Requirements Management" an article which examines this concept and its application more nearly was published in the magazine Testing Experience.

Different studies come to the following conclusion: approximately half of all system problems can be explained by unsatisfactory dealing
with requirements. The appreciation of the concept of Requirements Engineering frequently confines itself to customer requirements. However, during the system development new or changed requirements, e.g. test requirements arise in the form of test cases or reusable library specifications as a result of value-adding processes. The storage of this information in different data repositories aggravates the transparency and the comparison of project knowledge as well as traceability, as demanded by various (safety critical) standards (e.g. CMMI). Effectively dealing with this project knowledge (Knowledge Engineering) contains an enormous potential for
improving quality in daily project work.

The magazine article shows how the consistency of the different knowledge entities can be guaranteed.
