Measuring Complexity of SAP Systems

Ilja Holub, Tomas Bruckner
2016 Complex Systems Informatics and Modeling Quarterly  
The paper discusses the reasons of complexity rise in ERP system SAP R/3. It proposes a method for measuring complexity of SAP.  ...  Based on this method, the computer program in ABAP for measuring complexity of particular SAP implementation is proposed as a tool for keeping ERP complexity under control.  ...  For dimension i in phase f we can define complexity C f (D i ) as the number of entities (elements and/or links) of its model.  ...

Extending Business Process Models with Appreciation

Irina Rychkova, Gil Regev, Alain Wegmann
2019 Complex Systems Informatics and Modeling Quarterly  
This model represents the appreciative systems of process participants. Understanding these appreciative systems is necessary to make explicit the misfit between the model and the observed reality.  ...  We use Vickers' Appreciative System to model the homeostatic states with Harel's statecharts.  ...  Harel [6] created for the specification and analysis of complex discrete-event systems.  ...

Business Processes Modeling Recommender Systems: User Expectations and Empirical Evidence

Michael Fellmann, Novica Zarvić, Oliver Thomas
2018 Complex Systems Informatics and Modeling Quarterly  
We explain possible causes of this mismatch and finally hypothesize on two "sweet spots" of process modeling recommender systems.  ...  In this contribution, we apply recommender functionalities to business process modeling and investigate their potential for supporting process modeling.  ...  A further characteristic of recommender systems is that complex systems do not always perform better in evaluations than simple systems.  ...

The Diversity of Enterprise Modeling – a Taxonomy for Enterprise Modeling Actions

Ulf Seigerroth
2015 Complex Systems Informatics and Modeling Quarterly  
These modeling decisions have previously been of a more tacit nature and the taxonomy is supposed to make the rationale behind different modeling decisions explicit and understandable.  ...  Both researchers and practitioners have recognized the need for developed knowledge about enterprise modeling.  ...  IT and Information systems (IS) are mainly to be understood as action and communication systems [18] .  ...

Effort Estimation in BPMS Migration

Christopher Drews, Birger Lantow
2018 Complex Systems Informatics and Modeling Quarterly  
Beforehand, risk and effort must be evaluated. This work provides a framework for effort estimation regarding the technical aspects of BPMS migration.  ...  Business Process management Systems (BPMS) are highly integrated in the IT of organizations. They are at the core of business. Thus, migrating from one BPMS solution to another is not a common task.  ...  However, based on existing executable process model standards like BPEL or XPDL there may be the case of a shared execution engine of different BPMS.  ...

A Formal Method for Conceptual Fit Analysis

Antoni Olivé
2015 Complex Systems Informatics and Modeling Quarterly  
We formally define the notion of conceptual misfit and we present a method that determines the conceptual misfits between the user requirements and a set of candidate systems.  ...  The method consists of defining a superschema, expressing the user requirements and the implementation of the candidate systems on the basis of that superschema, and the automatic computation of the existing  ...  Acknowledgments This work has been partly supported by the Ministerio de Economía y Competitividad and FEDER under project TIN2008-00444, Grupo Consolidado, and by the Secretaria d'Universitats i Recerca  ...

Dierk Jugel
2018 Complex Systems Informatics and Modeling Quarterly  
In addition, hardly any tools are used for analysis of complex model characteristics.  ...  Due to the high number of relationships between these elements, architectural analysis mechanisms are essential for all stakeholders to keep track and to work out relevant model characteristics.  ...  Introduction Enterprises are complex and integrated systems of processes, organizational units, resources and technologies with a multitude of relations and interdependencies.  ...
