Quality and comprehension of UML interaction diagrams-an experimental comparison

Our results indicate that collaboration diagrams are easier to comprehend than sequence diagrams in RT systems, but there is no difference in comprehension of the two diagram types in MIS. Irrespective of the diagram type, it is easier to comprehend interaction diagrams of MIS than of RT systems. With respect to diagram quality, in the case of MIS, analysts create collaboration diagrams of better quality than sequence diagrams, but there is no significant difference in quality of diagrams created in RT systems. Irrespective of the diagram type, more correct diagrams are created in MIS applications than in RT applications.
