Strengths of UML-HAZOP UML Defect detection in UML diagrams A structured review method for UML diagrams guided by keywords (NO, MORE, LESS, ..) An interesting checklist for UML diagrams Experimental evaluation shows that the method is quite efficient (defects detected per unit of time) Weaknesses of UML-HAZOP Limited to class diagrams only. Limited to two kinds of relationships in class diagrams, Association and Generalization, from which 10 primary keywords are derived. In the presented experiments all the analysis was performed by one reviewer whilest HAZOP relies on multidisciplinary teams. Introduction .. the great advantage of the technique is that it encourages the team to consider less obvious ways in which a deviation may occur (..) In this way the study becomes much more than a mechanistic check-list type of review. [L
