An Improved User Requirements Notation (URN) Models’ Construction Approach

Semi-formal software techniques have been very successful in industry, government institutions and other areas such as academia. Arguably, they owe a large part of their success to graphical notation, which is more human-oriented than counterpart text-based formal notation techniques. However, ensuring the consistency between two or models one known challenges these This work looks closely at specific case User Requirements Notation (URN) technique. Although abstract model URN provides for link elements ensure its main components, namely, Goal-Oriented Requirement Language (GRL) Use Case Maps (UCM), effective implementation links yet be fully addressed. paper performs detailed analysis existing construction process proposes an improved with some guidelines ensure, by construction, correctness GRL UCM models. A study used throughout illustrate suggested solution.
