 Enterprise Modeling (EM) is used for a wide range of purposes such as developing business strategies, business process restructuring, business process orientation and standardization, eliciting information system requirements, capturing best practices, etc. A common challenge impeding the value and impact of EM is insufficient model quality. Despite substantial attention from both researchers and commercial vendors of methods the current situation in practice with respect to the quality of models produced is not satisfactory. Many modeling projects produce bad models that are essentially useless. The objective of this paper is to introduce a format, anti-patterns, for documenting critical don'ts in EM and to demonstrate the potential of the format by using it to report a set of common and reoccurring pitfalls of real life EM projects. We use the format of anti-pattern for capturing the bad solutions to reoccurring problems and then explain what led to choosing the bad solution. The anti-patterns in this paper address three main aspects of EM - the modeling product, the modeling process, and the modeling tool support.
