- Zeitschriftenartikel100 Years of Graphical Business Process Modelling(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 15, Nr. 3, 2022) Ralf Laue, Heinrich C. MayrIn December 1921, Frank B. and Lillian Moller Gilbreth held a presentation entitled “Process Charts” at the Annual Meeting of The American Society of Mechanical Engineers. They presented a diagrammatic notation for depicting work processes. This was the reason for initiating a call for papers for a special edition of the EMISA Journal. The aim of this issue is to reflect on the history of graphical business process modelling as well as on current and future challenges. In this editorial, we will shortly introduce the ideas behind the Process Charts method. We realize that some ideas discussed 100 years ago still remain highly relevant while modern work environment raises issues that would be unthinkable a century ago.
- ZeitschriftenartikelAn Actor-Oriented Model of a Service Provision(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 7, Nr. 1, 2012) Tackenberg, Sven; Duckwitz, Sönke; Schlick, Christopher M.The development of valid and efficient plans for service provision is a critical success factor for companies. Adequate planning assures the optimal use of resources, customer satisfaction, and the attainment of service targets in an acceptable period of time. Where these plans are incorrect or provide only a small contribution to the objectives of the company, resources are wasted and opportunities are missed. The problem of planning an efficient service provision can be described in the form of tasks that must be scheduled subject to precedence and resource constraints. Consequently, an analysis of existing scheduling models from the perspective of service providers is necessary to use them in the field of service management. The purpose of this paper is to provide a formal description of an actor-oriented model of a service provision that can be used for person-centered simulation. Such a model defines the decision variables and constraints to be determined by a person or a software tool during service management. Finally, we provide insight into the use of a formal model in case of a simulation study.
- ZeitschriftenartikelApplication of Enterprise Models for Engineering Enterprise Transformation(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 5, Nr. 1, 2010) Aier, Stephan; Gleichauf, BettinaEnterprise models constitute a valuable basis for enterprise transformation because they usually represent a widely accepted image of an enterprise. Practitioners often put a lot of effort in the creation and maintenance of such models that therefore represent a significant investment. However, so far the information contained in enterprise models is to a large extend ‘dateless’ which means it is hardly used to describe the transformation itself consistently. Therefore we propose a method to systematically derive an enterprise transformation model based on existing models representing enterprise structures at different points in time. The result of the method application is a set of project outlines derived from enterprise models. In order to generalise our approach to a multiperiod transformation model capable of coping with dynamic changes and plan deviations we propose a respective conceptual system. Our research artefact (the method) is finally demonstrated in a case study.
- ZeitschriftenartikelAn Approach to Flexible Multilevel Modelling(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 10, 2018) Macías, Fernando; Rutle, Adrian; Stolz, Volker; Rodriguez-Echeverria, Roberto; Wolter, UweMultilevel modelling approaches tackle issues related to lack of flexibility and mixed levels of abstraction by providing features like deep modelling and linguistic extension. However, the lack of a clear consensus on fundamental concepts of the paradigm has in turn led to lack of common focus in current multilevel modelling tools and their adoption. In this paper, we propose a formal framework, together with its corresponding tools, to tackle these challenges. The approach facilitates definition of flexible multilevel modelling hierarchies by allowing addition and deletion of intermediate abstraction levels in the hierarchies. Moreover, it facilitates separation of concerns by allowing integration of different multilevel modelling hierarchies as different aspects of the system to be modelled. In addition, our approach facilitates reusability of concepts and their behaviour by allowing definition of flexible transformation rules which are applicable to different hierarchies with a variable number of levels. As a proof of concept, a prototype tool and a domain-specific language for the definition of these rules is provided.
- ZeitschriftenartikelAutomated Assessment of Conceptual Models in Education(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 15, Nr. 2, 2023) Meike Ullrich, Constantin HouyIn Computer Science, Software Engineering, Business Informatics or Information Systems, conceptual modeling is an important tool and as such also contained in the respective curricular recommendations. Especially in large university courses, an automated assessment of models can improve the quality of teaching and learning. While there are many different approaches to automatically assess conceptual models, these approaches, however, often only tackle a single aspect or a single type of conceptual model. In this paper, we aim to take a comprehensive perspective on the topic and shed light on the current state of the art and technique. Furthermore, as assessment approaches have to be developed in accordance with appropriate teaching or learning activities and desired learning outcomes, we inquire in which settings automated assessment approaches are included and to which extent didactic aspects are taken into account. To this end, we have conducted a systematic literature review in which we identified 110 relevant publications on the topic which we have analyzed in a structured way. The results provide answers to five relevant research questions and pinpoint open issues which should be inquired in further research.
- ZeitschriftenartikelAutomatic Generation of Glossaries for Process Modelling Support(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 6, Nr. 1, 2011) Peters, Nicolas; Weidlich, MatthiasProcess models are often used for human to human communication. Besides other aspects, e.g., the chosen modelling notation or the model layout, the labelling has a strong influence on the understandability and, therefore, quality of a model. Consequently, labels should be reused and aligned across different process models. In order to support these goals, a glossary might be applied in the course of modelling. In this article, we argue that such a glossary can be generated automatically from the labels of an existing process model collection, e.g., a reference model. We introduce an approach for such a glossary generation that takes additional information on structural as well as control flow aspects into account. The applicability of our approach is illustrated by means of two case studies. Based thereon, we also report on findings regarding the appropriateness of the chosen structural and behavioural aspects.
- ZeitschriftenartikelBalancing Care and Paperwork(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 15, Nr. 11, 2020) Stertz, Florian; Mangler, Juergen; Rinderle-Ma, StefanieEffort and quality of care documentation are among the most pressing challenges in the nursing domain due to demographic development and compliance demands. Hence approaches for decreasing the effort of documentation while increasing its quality are required. This work introduces the idea of automatic task completion and documentation which is achieved through a process-aware solution where physical objects utilized during care tasks are equipped with NFC tags. Nine use cases from the care domain are identified with domain experts and implemented through a proof-of-concept prototype. The time reduction of employing this technology is assessed by domain experts within the typical routines in a nursing home. The interviews indicate an average decrease in documentation time per shift of more than 60%. Inherently also documentation quality is increased as automatic documentation prevents forgetting to document certain steps or other errors. On top, this work fosters two ways for comprehensive documentation, i.e., log-based documentation for analysis and monitoring tasks and paper-based documentation as typically expected by nurses. The logs are automatically created and stored by the underlying process engine. It is shown how paper-based documentation can be automatically created based on process logs. Overall, this work provides the basis for automatic, comprehensive, and continuous documentation of care tasks based on NFC technology.
- ZeitschriftenartikelBalancing Customer Requirements and IT Service Standardisation - A Procedural Reference Model for Individualised IT Service Agreement Configurations(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 6, Nr. 2, 2011) Brocke, Henrik; Uebernickel, Falk; Brenner, WalterIT service providers are increasingly urged to stringently align their service portfolio with the IT support of their customers’ business processes. Consequently, both IT expenses and its strategic contribution to value creation are expected to become subject to heightened transparency. Yet, in order to allow for standardised on-demand service request processing within the meaning of IT industrialisation, these services appear too adapted to individual customer needs, particularly as they are subject to continuous changes in business requirements. In order to address this issue, a three-phase procedural model of IT service agreement configuration is introduced: IT services thus remain transformable and configurable via predefined complementary services which are selected by configuring a customer’s individual service directory. In addition, the reutilisation of modular commitments in order to compose service specifications aims to maintain standardised IT operations. Serving as a procedural reference model, these configuration phases are introduced in detail regarding activities, roles, techniques and data structure as developed and implemented in Action Research cooperation with two IT providers.
- ZeitschriftenartikelBest Practices for Business and Systems Analysis in Projects Conforming to Enterprise Architecture(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 3, Nr. 1, 2008) Foorthuis, Ralph; Brinkkemper, SjaakThis paper aims to identify best practices for performing business and systems analysis in projects that are required to comply with Enterprise Architecture. We apply two qualitative research methods to study real-life projects conforming to architecture at Statistics Netherlands. First, a Canonical Action Research approach is applied to participate in two business process redesign projects. Second, we use Focus Group interviews to elicit knowledge about carrying out projects conforming to architecture. Based on this empirical research we present seven observations and ten best practices. The best practices point to the fact that project conformance is not only the responsibility of project members, but also of enterprise architects. Considering four levels of best practices (good idea, good practice, local best practice, industry best practice), we argue that our guidelines are located at the second (good practice) level. More research is required to prove or falsify them in other settings.
- ZeitschriftenartikelBig Data Management and Analysis for Business Informatics - A Survey(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 9, Nr. 1, 2014) Marchand-Maillet, Stéphane; Hofreiter, BirgitModern communication networks have fueled the creation of massive volumes of data that may be valued as relevant information for business activities. In this paper, we review technologies for enabling and empowering business activities, leveraging the content of this big data. We distinguish between data- and user-related technologies, and study the parallel brought by the overlap of these categories. We show how the trend of Big Data is related to data security and user privacy. We then investigate automated ways of performing data analysis for Business Intelligence. We finally review how groups of users may be seen as a workforce in business through the notion of human computation or crowdsourcing, associated with the notions of trust and reputation. We conclude by discussing emerging trends in the domain.
