The design of a “good” business process model is a time-consuming and error-prone task and requests high training effort from the process modeler. These barriers might be a reason why business processes are often designed with software tools, which were not intentionally developed for this purpose, but are highly familiar for the process modeler (e...
A variety of methods devoted to the behavior analysis of business process models has been suggested, which diminish the task of inspecting the correctness of the model by the process modeler. Although a correct behavior has been attested, the process model might still not be feasible because the modeler or intended user is hampered in her comprehen...

Business processes are the focal point when it comes to changes in an enterprise. Be it the implementation of new business models and strategies, be it in the realization of information systems, or be it related to quality improvements—the discussion always involves business processes. As a logical consequence follows the necessity for a realistic...
The design of business processes is not a new discipline but is essentially as old as the creation of products and labor services. Over time, the originally purely experiential approach has been augmented by an engineering component so that one speaks today of business process engineering. This circumscribes the design and layout, the analysis, imp...
In this concluding chapter, we gather several thoughts on how the future of business process engineering might look like. Topics and technologies that from our perspective will definitely have an impact include virtual worlds and 3D graphics on the one hand, and socialization on the other. The latter has been brought along by Web 2.0 developments a...
Petri nets are impressive in business process modeling due to the simplicity of the graphical presentation in connection with their expressive power. One can achieve a high precision of models, and the operational semantics allows formal for analysis and dynamic simulation. Practice shows, however, that a powerful modeling language alone is not eno...
In this chapter, the concepts and modeling languages are introduced which are required for modeling, particularly of processes, objects, and organization structures in the remainder of this book. Initially, there is a brief explanation of the necessity and the motivation behind modeling. As a concrete modeling language for processes, Petri nets are...

The basic idea of business process modeling is to identify the set of activities which has to be performed to reach a particular goal and to define a partial order on that set. A mobile business process is a process which has instances where individual activities are performed using a mobile computer like a PDA or a smartphone. The contribution of...
Knowledge of modeling language syntax is usually not sufficient for building “good” process models. Profound modeling experience
is required to apply a modeling language in practice. The productivity of users without any modeling experience is low and
thus the quality of the modeling result may be unsatisfying if respective modeling tool support is...
Offshore outsourcing software development (OOSD) is increasingly being used by the Software Industry. OOSD is a specific variant of Geographically Distributed Software Development
(GDSD). Compared to the traditional mode of software development (i.e., in-house) GDSD is more edgy and puts at risk the attainment of the expected results. Although the...
