On the one hand, the contribution explains in a general way the benefits of flexible visual modeling by allowing a lively development process through relaxing the formal requirements for artefacts in the work process. On the other hand, the contribution shows a concrete example and explains an implementation in a tool, in particular how to cover whole-part relationships, generalization and an improved handling for association multiplicities. The aim is to give developers the option to let their ideas flow in a free way with few creativity restrictions by a tool. Flexibility may be gained by transitioning in the work process between specific, instance-based visual models and generic, type-based visual models where both kinds of models allow for incompleteness or inconsistency.8enhttps://creativecommons.org/licenses/by/4.0/Object modelClass modelFlexible modelingIncomplete modelInconsistent model000 Informatik, Informationswissenschaft, allgemeine Werke::000 Informatik, Wissen, SystemeText::Konferenzveröffentlichung::Tagungsband::Konferenzbeitrag10.26092/elib/4196urn:nbn:de:gbv:46-elib222241
