Operational building blocks for business process modelling

The modelling of business processes is a rather complex, difficult and therefore time-consuming process. The efficiency of this process can be significantly enhanced by employing reusable building blocks, rather than to describe business processes from scratch every time a model is being created or modified. The paper describes a reference model which identifies a set of generic building blocks needed for enterprise modelling and identifies their relationships. Further specialisation of these generic building blocks into a profession and/or industry branch oriented set enables business people to model their processes with a minimum requirement on IT know-how. The CIMOSA concepts and language have been selected as the basis for the reference model. Since CIMOSA is one of the basic concepts recognised in the relevant standardisation work, the presented approach also obeys very closely the relevant European and international standards.     

Agile enterprise architecture modelling: Evaluating the applicability and integration of six modelling standards

ContextAgile enterprise architecture artefacts are initially architected at the high-level and the details of those artefacts iteratively evolve in small project increments. There is a need to model agile enterprise architecture artefacts both at the high and low detailed level for a particular context. ArchiMate is relatively a new high-level architecture modelling standard. There is a growing interest amongst organisations in applying ArchiMate for high-level agile enterprise architecture modelling. However, organisations are unsure how to effectively apply ArchiMate at high-level and integrate it with their existing low detailed level modelling standards in practice for supporting end-to-end agile enterprise architecture modelling.ObjectiveThis paper evaluates the applicability and integration of high-level ArchiMate modelling standard with the existing low-level modelling standards such as BPMN (Business Process Model and Notation), UML (Unified Modelling Language), FAML (FAME [Framework for Agent-Oriented Method Engineering] Language), SoaML (Service Oriented Architecture Modelling Language), and BMM (Business Motivation Model).MethodA qualitative questionnaire-based evaluation criteria has been developed based on the well-known and comprehensive The Open Group Architecture Framework (TOGAF). The evaluation criteria has been applied to evaluate the applicability and integration of the selected six modelling standards from the business, application, infrastructure and extension perspectives.ResultsEach modelling standard is different in scope. A single modelling standard usually does not provide the kind of support required by the agile enterprise architecture modelling. Based on the review results, a hybrid enterprise architecture modelling approach is proposed. This paper demonstrates the application of the proposed hybrid approach with the help of an agile enterprise architecture modelling case study.ConclusionIt is concluded that the ArchiMate does not replace the existing low-level modelling standards, rather it can be used in conjunction with low-level modelling standards. This calls for the adoption of hybrid and integrated approach for agile enterprise architecture modelling.     

CIMOSA: enterprise engineering and integration

Enterprises are rather complex systems which have to be managed for their internal affairs, but more importantly for the many relations to the different environments in which they are operating. Today, these environments are changing much more rapidly and the need for relevant information becomes of paramount importance in the decision making processes at all levels of enterprise management. Fluctuations in market demands, technology evolution and changing regulations require very flexible enterprise operations, capable of reacting to those changes. These reactions must be based on relevant and up-to-date information which must be supported by new decision support technology. The challenges in decision support concern the identification of relevant information, easy access and intelligent use of this information. Building and maintaining the enterprise knowledge base and enabling its efficient use for decision support are major tasks of enterprise engineering. Enterprise integration and its subsequent operation in the global environment of customers, suppliers and regulatory bodies will heavily depend on the availability and the continuous extension of this knowledge base. Enterprise modelling will play an important role in creating the knowledge base and in using it for enterprise integration and operational decision support. The paper discusses enterprise engineering as an enterprise life-cycle oriented discipline for identification, design, and implementation of enterprises and their continuous evolution. Current problems in the field are identified and initiatives are presented.     

A conceptual framework for understanding business processes and business process modelling

It is increasingly common to describe organizations as sets of business processes that can be analysed and improved by approaches such as business process modelling. Successful business process modelling relies on an adequate view of the nature of business processes, but there is a surprising divergence of opinion about the nature of these processes. This paper proposes a conceptual framework to organize different views of business processes under four headings. It also aims at providing an integrated discussion of the different streams of thought, their strengths and limitations, within business process modelling. It argues that the multifaceted nature of business processes calls for pluralistic and multidisciplinary modelling approaches.     

Enterprise modelling methodology for forward and reverse supply chain flows integration

The paper proposes a new enterprise modelling methodology called ERE-GIO applicable to supply chain reengineering and integration. It is based on two major phases: reverse engineering of the supply chain and then forward engineering. It takes advantages of previous enterprise modelling methodologies, especially CIMOSA. The application of the defined methodology on the logistics flow of an industrial company has allowed the integration of the reverse logistics flows in the traditional supply chain, thanks to the modelling of business processes and the flows related to it.     

Modelling non-functional requirements of business processes

This paper presents an approach to the identification and inclusion of ‘non-functional’ aspects of a business process in modelling for business improvement. The notion of non-functional requirements (NFRs) is borrowed from software engineering, and a method developed in that field for linking NFRs to conceptual models is adapted and applied to business process modelling. Translated into this domain, NFRs are equated with the general or overall quality attributes of a business process, which, though essential aspects of any effective process, are not well captured in a functionally oriented process model. Using an example of a healthcare process (cancer registration in Jordan). We show how an analysis and evaluation of NFRs can be applied to a process model developed with role activity diagramming (RAD) to operationalise desirable quality features more explicitly in the model. This gives a useful extension to RAD and similar modelling methods, as well as providing a basis for business improvement.     

New perspectives in ontological analysis: Guidelines and rules for incorporating modelling languages into UEML

Ontological analysis of modelling languages has been mainly used for evaluating quality of modelling language w.r.t. one specific upper ontology. Generally speaking this evaluation has been done by identifying the coverage of the modelling language constructs w.r.t. the ontology and vice-versa. However, a quite limited support has been developed for performing the ontological analysis task. Specifically, various ontologies used for ontological analysis are not associated to a machine readable format; the coverage of modelling language constructs is mostly provided by informal tables mapping one construct on to one ontological concept; the way in which this coverage task is undertaken is poorly specified (resulting in distinct results for distinct experts involved), and finally, preventing any ontology enrichment for dealing with some specialised language constructs. This limited support also prevents application of ontological analysis outcomes to problems and domains dealing with interoperability, integration and integrated usage of enterprise and IS models, which is today one of the key aspects for making interoperable, maintainable and evolvable inter and intra enterprise software systems. The paper provides an overview of the Unified Enterprise Modelling Language (UEML) approach, which introduces advanced support to ontological analysis of modelling languages. The paper is specifically focused on the task of ontological analysis of modelling languages (named incorporation of modelling languages) by introducing and explaining several guidelines and rules for driving the task: therefore, not all the aspects of the UEML approach will be discussed through the paper. The guidelines and rules are illustrated by incorporation of three selected modelling constructs from IDEF3, a well known language for specifying enterprise processes.     

A visual language and environment for enterprise system modelling and automation

ObjectiveWe want to support enterprise service modelling and generation using a more end user-friendly metaphor than current approaches, which fail to scale to large organisations with key issues of “cobweb” and “labyrinth” problems and large numbers of hidden dependencies.MethodWe present and evaluate an integrated visual approach for business process modelling using a novel tree-based overlay structure that effectively mitigate complexity problems. A tree-overlay based visual notation (EML) and its integrated support environment (MaramaEML) supplement and integrate with existing solutions. Complex business architectures are represented as service trees and business processes are modelled as process overlay sequences on the service trees.ResultsMaramaEML integrates EML and BPMN to provide complementary, high-level business service modelling and supports automatic BPEL code generation from the graphical representations to realise web services implementing the specified processes. It facilitates generated service validation using an integrated LTSA checker and provides a distortion-based fisheye and zooming function to enhance complex diagram navigation. Evaluations of EML show its effectiveness.ConclusionsWe have successfully developed and evaluated a novel tree-based metaphor for business process modelling and enterprise service generation. Practice implications: a more user-friendly modelling approach and support tool for business end users.     

Business process management—the third wave: business process modelling language (bpml) and its pi-calculus foundations

This paper introduces the ideas behind BPML, the business process modelling language published by BPMI. BPML provides a process-centric (as opposed to a datacentric) metalanguage and execution model for business systems. It is underpinned by a strong mathematical foundation, the pi-calculus. The current paper is derived from supplementary appendices to a book which describes a ‘third wave’ approach to business process management [Business Process Management: The Third Wave, 2003]. The aim is to model business processes directly in an executable form, so that the mobility and mutability inherent in business behaviour is reflected and supported in the corresponding IT systems, erasing the present IT-business divide.     

An application of CIMOSA concepts in the development of change capable manufacturing cells

A new approach to the design and reconfiguration of change capable manufacturing cells is described. The approach is based on (i) the development of particular models of cells, where the use of CIMOSA modelling constructs is structured and informed by a semi-generic model of similar manufacturing cells and (ii) the use of new constructs and tools that operationalise particular models in the form of an explicit, model-based configuration of cell resources and software components. The paper describes key elements of the semi-generic model and a case study application of the approach when designing and prototyping a case study manufacturing cell.     

CEN standardization activities related to CIMOSA

The paper describes the work of standardization committee CEN TC310 WG1 and its predecessor on manufacturing standards for Systems Architecture and in particular Enterprise Modelling for CIM. That work builds upon a common conceptual high-level framework (ENV 40 003:1991), heavily based on input from CIMOSA, within which key enterprise modelling concepts can be identified. A later standard (ENV 12204:1995) sets out thirteen ‘modelling constructs' necessary for computer-based modelling of enterprises, focusing on discrete parts manufacturing. In late 1998 WG1 was developing a draft ENV (‘EMEIS') on the services required to develop, execute (enact) and integrate enterprise models on an open ICT platform. The paper concludes with areas of possible future work on revising the Framework, on Human Issues, on Construct Modelling and on providing guidance in the use of modelling constructs.     

On qualitative modelling

Fundamental assumptions behind qualitative modelling are critically considered and some inherent problems in that modelling approach are outlined. The problems outlined are due to the assumption that a sufficient set of symbols representing the fundamental features of the physical world exists. That assumption causes serious problems when modelling continuous systems. An alternative for intelligent system building for cases not suitable for qualitative modelling is proposed. The proposed alternative combines neural networks and quantitative modelling.     

Building a production planning process with an approach based on CIMOSA and workflow management systems

Nowadays, one of the major challenges for enterprises is to stay competitive in today's changing market environment. This can be supported by business process models which on one hand are consistent and adequate (requirement #1), and on the other hand can be enacted and operated in an easy, fast, straightforward and integrated way (requirement #2). The CIMOSA architecture provides the basis for business process modelling to fulfil both of the above requirements. It supports the creation of consistent process models and allows to identify almost all the information required for the development of a workflow model. These models can be implemented using one of the commercial workflow management systems. In this paper we present the methodology based on the CIMOSA architecture that we have developed to build a workflow model in ©Lotus Notes for the forecasting and production planning processes in a tiles manufacturing enterprise. The CIMOSA approach has also been used to design the necessary software applications for processing the information of the resulting workflow system.     

Towards the construction of workflow-suitable conceptual modelling techniques

Despite their high-level and graphical nature, workflow specifications require a significant amount of implementation detail — for example application programming interface, database access and programming mechanisms for information flow — for a more comprehensive validation than is currently possible. This is currently recognized as a deficiency in workflow conceptualization. Although conceptual modelling techniques are available which are expressive, comprehensive and precise enough, we believe, their concepts and features are not specialized enough for workflow domains. In this paper, we offer a comparative insight into techniques which characterize different aspects and approaches of workflow specifications. These are: structured process modelling, object-oriented modelling, behavioural process modelling and business-oriented modelling. In particular, we determine gaps for workflows capturing operational business transaction processing, for example those of insurance claims, bank loans and government-related registration. For technique construction, we describe five workflow suitability principles.
