Due to the increase of their complexity, currently engineered sys-tems cannot be developed by one individual, but are a product of acollaboration between multiple stakeholders who develop the sys-tem from different domain-specific views. Inconsistencies betweenviews, however, hinder collaboration and therefore, must be man-aged. Since the encountered inconsistencies may potentially dis-appear as the natural consequence of a design workflow, toleratingthem to a given extent may be desirable and can lead to a more effi-cient collaboration. A key to reason about tolerance is the quantifi-cation of the impact of single inconsistencies on the overall systemdesign.In this paper we present a quantification model for semantic in-consistencies in discrete and continuous systems. We investigatecharacteristic behavioral patterns of inconsistencies based on thismodel and identify the links with various forms of tolerance. Fi-nally, we discuss the directions of further expanding the approachrequired for a comprehensive inconsistency tolerance technique.
