This contribution presents a method to evaluate business applications. The method allows for using artifacts of enterprise architectures. Artifacts like business processes or hardware can exert influence on the application's quality and thus have to be regarded. A central aspect is to modularize the method's basic components, which are key figures and their metrics. The modularization allows for flexible usage and customization to fit the heterogeneity of different organizations. To make the method more intuitive, a key figure is encapsulated by a fuzzy logic based component denoted as criterion. A criterion addresses a certain aspect to evaluate an application and allows for using linguistic terms to represent a key figure.
