19. GESSI Software Engineering Research Group – www.lsi.upc.edu/~gessi/ DesCOTS-EV: Evaluate a product Mail Server Evaluator The evaluation of a quality entity, depends on the metrics that these quality entities have assigned. Basic attributes - simple metrics (boolean, integer,...) and structured (set, tuple, domain, function) Derived attributes - formula from the value of its sub-attributes Characteristics, Subcharacteristics - subjective metrics Assign a value to the attribute "DefaultFolders", that has a set metrics
