    A Graphical Method for Conceptual Modelling of Business and Software Scenarios2012In: New Trends in Software Methodolodies, Tools and Techniques / [ed] Hamido Fujita and Roberto Revetria, Amsterdam: IOS Press, 2012, p. 238-253Conference paper (Refereed)
    Abstract [en]

    Abstract. Modelling method, which is defined by simple interaction loops between organizational and technical components can be viewed as fundamental elements for decomposition of complex business scenarios. This is important for separation of crosscutting concerns. The paper proposes a new graphical method that allows limited human mind to focus and to visualize one particular concern at a time. It also suggests design principles for the semantic integration of business and software scenarios. Separation of crosscutting concerns is performed on a basis of the standard transaction pattern. The presented modelling method can be used for introducing the evolutionary changes of requirements. This is important for managing complexity of information systems conceptualizations, especially when new changes are introduced.  It targets both business process modelling experts and information system designers. The ultimate goal of the new method is to construct and visualize business scenarios with a more comprehensible structure.

    Keywords. Service interactions, value flows, separation of concerns, cancellation patterns.

    Service-Oriented Foundation and Analysis Patterns for Conceptual Modeling of Information Systems2009In: Information Systems Development: Challenges in Practice, Theory, and Education. Volume 1 / [ed] Wita Wojtkowski, Gregory Wojtkowski, Michael Lang, Kieran Conboy, Chris Barry, New York: Springer , 2009, p. 249-265Chapter in book (Refereed)
    Abstract [en]

    Everyday companies are inventing new configurations of service architectures, which prescribe and motivate information system design. Information system architectures are intrinsically complex engineering products that can be defined on different levels of abstrac-tion and represented by using various dimensions. Designers are building them fragment by fragment but when the design is complete, then typically the business and technical compo-nents do not fit each other. The attempt to maintain the relevance of each specification frag-ment across disparate dimensions is very expensive and time consuming. The notion of service is not used explicitly in traditional information system engineering methods, which cover just a part of required modelling notations that are currently emerging under the service - oriented analysis and design approaches. The most fascinating idea about the service concept is that it applies equally well to organizational as well as technical components, which can be viewed as service requestors and service providers. The primary goal of service oriented architecture is to align the business process models with the information system design in order to make both organizational and technical system parts more effective. One of the reasons why the traditional methods do not provide effective support for engineering of information systems is that service architectures are difficult to visualize and comprehend for business experts who determine the organizational strategies. The main goal of this paper is to present a new ser-vice-oriented foundation and the associated analysis patterns for computation neutral informa-tion system modelling. A service concept integrates various information system dimensions of static and dynamic aspects into one modelling notation

    Three Conceptual Modeling Patterns of Semantically Integrated Method2014In: BUSTECH 2014, The Fourth International Conference on Business Intelligence and Technology, IARIA , 2014Conference paper (Refereed)
    Abstract [en]

    System modeling patterns are similar to workflow patterns, which were established with the purpose of delineating the requirements that arise during business process modeling on a recurring basis. Traditionally, only dynamic aspects are used for specification of modeling patterns leaving aside the static aspects of business processes. The paper presents three conceptual modeling patterns where integrity of totally different aspects can be analyzed. The advantage of such a modeling approach is that it enables visualization and integration of different modeling dimensions of information system specifications in a single diagram. Many graphical representations do not allow such a visualization and an integration of static and dynamic aspects.

    Conceptual Modeling Method for Separation of Concerns and Integration of Structure and Behavior2012In: International Journal of Information System Modeling and Design, ISSN 1947-8186, E-ISSN 1947-8194, Vol. 3, no 1, p. 48-77Article in journal (Refereed)
    Abstract [en]

    Identification of discontinuities, separation of concerns and dealing with the evolutionary changes of requirements is difficult in conceptual modeling. Another restriction is that a limited human mind allows focusing on one particular requirement at a time in isolation. One fundamental problem is that all conventional conceptual modeling techniques are dealing with collections of loosely linked meta-models, which are defined by the different types of diagrams. Typically, system development methods project interactive, behavioral and structural aspects of information systems’ conceptual representations into disparate views. Therefore, the semantic integrity of various architecture dimensions is difficult to achieve. The difficulties are stemming from the paradigmatic mismatch between static and dynamic constructs. The advantage of the conceptual modeling approach presented in this paper is flexibility in dealing with the evolutionary changes of requirements. Visualization of interplay among structural, interactive and behavioral aspects helps to separate different concerns and to identify discontinuities of conceptual representations. It is demonstrated by case study examples that sequential, underlying, enclosing, overriding and overlaying interaction loops between actors provide the foundation for the composition of complex scenarios, which span across organizational and technical system boundaries. The presented semantic integration and system decomposition principles target both business process modeling experts and information system designers, because they are essential for introducing evolutionary changes and for managing complexity of information system conceptualizations.

    Interactions, Transitions and Inference Rules in Semantically Integrated Conceptual Modelling2016In: Proceedings of the Sixth International Symposium on Business Modeling and Software Design, Bulgaria: SciTePress, 2016, p. 11-21Conference paper (Refereed)
    Abstract [en]

    To obtain value from the graphical representations that are used by different stakeholders during the system development process, they must be integrated. This is important to achieve a holistic understanding about system specification. Integration can be reached via modelling process. Currently, most of information system modelling methods present different modelling aspects in disparate modelling dimensions and therefore it is difficult to achieve semantic integrity of various diagrams. In this paper, we present semantically integrated conceptual modelling method for information system analysis and design. The foundation of this modelling method is based on interactions. This way of modelling provides possibility of integration of business processes and business data. The inference rules of interactions help in reasoning about the decomposition of concepts. In this method, decomposition of the system is graphically described as classification, inheritance or composition of organizational and technical system components.

    Pragmatic-Driven Approach for Service-Oriented Analysis and Design2008In: Information Systems engineering: From Data Analysis to Process Networks / [ed] P.Johannesson & E. Söderström, New York: IGI Global, 2008, p. 97-128Chapter in book (Other academic)
    Abstract [en]

    This chapter presents a pragmatic-driven approach for service-oriented information system analysis and design. Its uniqueness is exploiting a design foundation for graphical description of the semantic and pragmatic aspects of business processes that is based on the service oriented principles. Services are viewed as dynamic subsystems. Their outputs depend not only inputs, but on a service state as well. A precondition state and input flow is sufficient for determining a service output flow and a post-condition state. Intentions of various business process experts are represented in terms of a set of pragmatic dependencies, which are driving the overall system engineering process. It is demonstrated how the pragmatic aspects are linked to the conceptual representations, which define the semantics of business design. In contrast to the traditional system development methodologies, the main difference of the service-oriented approach is that it integrates the static and dynamic aspects into one type of diagram. Computation independent models of semantic fragments are represented by graphical specifications of interactions between service providers and service consumers. Semantic integrity control between the static and dynamic dependencies of business processes is a one of the major benefits of service-oriented analysis and design process. It is driven by the pragmatic descriptions, which are defined in terms of goals, problems and opportunities.

    Principles of Semantically Integrated Conceptual Modelling Method2017In: Business Modeling and Software Design / [ed] Boris Shiskov, Switzerland, Cham: Springer, 2017, p. 1-27Conference paper (Refereed)
    Abstract [en]

    Abstract. To obtain value from the graphical representations that are used by different stakeholders during the system development process, they must be integrated. This is important for achieving a holistic understanding about system specification. Integration can be reached via modelling process. Currently, most of information system modelling methods present different modelling aspects in disparate modelling dimensions and therefore it is difficult to achieve semantic integrity of various diagrams. In this paper, we present the principles of semantically integrated conceptual modelling method for information system analysis and design. The foundation of this modelling method is based on interaction flows. This way of modelling is critical for the identification of discontinuity and inconsistency in information systems specifications. It also provides possibility to integrate business processes and business data, which is necessary for the integration of various architectural domains and to reach the holistic view of enterprise architecture. We have explained in object-oriented terms how interactive, structural and transitional aspects are merged. We also demonstrated the interpretation of various patterns, in terms of semantically integrated conceptual modelling method. It was shown that the method has sufficient expressive power to cover some special cases, which do not match the standard pattern of transaction. The inference rules of interactions help in reasoning about system decomposition. In this method, decomposition is graphically described as classification, inheritance or composition of concepts. SICM method is based on a single type of diagram, which enables reasoning about integration with the help of a special set of inference rules. The ultimate goal of this paper is to present the generic principles for computation- neutral modeling of service interactions.

    Keywords: Conceptual modelling, Modelling aspects, Service interactions, Consistency, Value flows, Inference rules, Decomposition, Object transitions.

    Semantically Integrated Conceptual Modeling Method and Modeling Patterns2014In: Systems and Software Development, Modeling and Analysis: New Perspectives and Methodologies / [ed] Khosrow-Pour, Mehdi, USA: IGI Global, 2014, p. 1-33Chapter in book (Refereed)
    Abstract [en]

    Managing evolutionary changes, identification of discontinuities and separation of concerns is not an easy task in the area conceptual modeling in information system development. One of the fundamental problems is that most conventional conceptual modeling techniques deal with the collections of loosely linked meta-models, which are defined by the different types of diagrams. Typically, system development methods project interactive, behavioral and structural aspects of information systems conceptual representations into disparate views. Therefore, the semantic integrity of various architecture dimensions is difficult to achieve. In this paper we present semantically integrated conceptual modeling method. The advantage of this method is stability and flexibility of the diagrams to manage the constant changes of system requirements. This method provides possibility to visualize the interplay among structural, interactive and behavioral aspects. This is very important for the control of semantic integrity and to maintain a holistic representation, where external and internal views of service conceptualizations are visualized together. Such visualization is also important for separation of concerns which provides foundation for creation of modeling patterns. Modeling patterns are important for several reasons. First, they can be used for demonstration of the interplay of fundamental constructs that are used for system analysis and design. Secondly, modeling patterns are important for the evaluation of the expressive power of semantic modeling languages. It is demonstrated by case study examples that sequential, underlying, enclosing, overriding and overlaying interaction loops between actors provide the foundation for the composition of complex scenarios, which are spanning across organizational and technical system boundaries.

    Towards the Enterprise Engineering Approach for Information System Modelling across Organisational and Technical Boundaries2003In: Enterprise Information Systems V: Part 3, Springer, 2003, p. 204-215Conference paper (Refereed)
    Abstract [en]

    Enterprise Engineering proved to be useful when a generally accepted intentional description of information system is not available. A blueprint of enterprise infrastructure provides a basis for system analysis of the organizational and technical processes. It is sometimes referred as enterprise architecture. The major effort of this paper is the demonstration of how to bridge a gap among various levels (syntactic, semantic and pragmatic) of enterprise engineering. Most information system engineering methodologies are heavily centred on system development issues at the implementation level. Thus, such methodologies are restrictive in a way that a supporting technical system specification can not be motivated or justified in the context of organizational process models. Enterprise models provide a basis for gradual understanding of why and how various technical system components come about. Some undesirable qualities of enterprise engineering are sketched in this paper

    Abstract [en]

    This document demonstrates a possibility for extension of the LYEE methodology by using the Enterprise Modelling approach. The Karlstad University unit undertook the work. The major contribution of this report from the practical point of view is to illustrate by various examples how enterprise modelling approach can contribute in the phase of system requirements engineering in the context of LYEE. The overall investigation is based on examples of a real case study in the area of e-commerce. Most software methodologies are heavily centred on system development issues at the implementation level. Thus, such methodologies are restrictive in a way that a supporting technical system specification can not be motivated or justified in the context of organisational process models. A blueprint of enterprise infrastructure provides a basis for the organisations information technology planning. It is sometimes referred as enterprise architecture. The major theoretical effort of this report is to demonstrate the Lyee software engineering methodology extensions by using the enterprise modelling approach. The main focus is on the issue of the pragmatic, semantic and logical software requirements integration by using the enterprise models.

    Abstract [en]

    Abstract. Rapid changes in business environment result in necessity to introduce new agile modeling methods, which effectively support evolution of information system specifications. Service oriented paradigm can be applied for achievement of this goal. Conceptual models of service interactions are important as a natural principle for the separation of crosscutting concerns of various information system architecture dimensions. This paper presents a modeling method for systems analysis and design, where service orientation is used for integration of information system conceptualizations. Goals, problems and opportunities represent pragmatic aspects, which are considered as a driving force of design process. It is a starting point for reasoning about changes of computation neutral specifications of service architectures across organizational and technical system boundaries. The presented method is used for bridging pragmatic and semantic dimensions of information systems specifications

    Development of a new service-oriented modelling method for information systems analysis and design2010Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis presents a new modelling method for information systems analysis and design, where the concept of service and the principles of service orientation are used for integrated modelling and reasoning about information systems architectures across organisational and technical systems boundaries. The concept of service enables cohesion of the intersubjective and objective modelling traditions by using a single type of diagram that facilitates detection of semantic inconsistency, incompleteness, ambiguity and discontinuity between the static and dynamic aspects of information systems specifications. The thesis is focused on three research topics, which are fundamental to the development of a new service-oriented modelling method. The first research topic concerns a pragmatic-driven specification of information systems. It clarifies answers to the research question: How can a conceptual modelling process be driven by pragmatic considerations? The second research topic provides a service-oriented modelling foundation for information systems analysis and design. It answers the research questions: How can the concept of service be used explicitly for the analysis and design of information systems and how can the static and dynamic aspects of information systems specifications be integrated at the conceptual level? The third research topic presents transition principles to implementation-specific design and answers the research question: How can service-oriented conceptual representations be aligned with implementation-specific design?

    The thesis contributes with a new knowledge to the area of conceptual modelling of information systems. The service-oriented modelling method consists of the modelling process, modelling language and techniques for the analysis and design of information systems on three levels of abstraction: pragmatic, semantic and syntactic. These three levels are necessary for a holistic understanding of enterprise architecture by stakeholders. The advantage of the service-oriented modelling method is that it can help to control traceability from information system design to original requirements. The method facilitates the semantic integration of the structural, behavioural and interactive aspects of information systems conceptual representations by using a single diagram type. The modelling language provides service-oriented constructs that are fundamental to building the major systems analysis patterns. The service-oriented modelling process contributes with seven steps of incremental design, which justifies various information systems components. The method provides the basis for a gradual and systematic way of modelling and an understanding of how pragmatic, semantic and logical information system requirements are linked together. The possibility to detect and eliminate undesirable characteristics of service-oriented diagrams can help to improve communication among stakeholders. Service-oriented specifications are computation-neutral and therefore they are more comprehensible for business analysis experts in comparison to implementation specific graphical representations of information systems. Finally, this thesis presents the challenges for future research, one of which is the development of the automated tools for the alignment of business models with implementation-specific information systems specifications.

    Visualization for Open Access- A case Study of Karlstad University and the University of Makerere in Uganda2018In: Information and Software Technologies / [ed] Damaševičius, Robertas, Vasiljeviene, Giedre (Eds.), Switzerland: Springer, 2018, p. 187-197Conference paper (Refereed)
    Abstract [en]

    Open Access (OA) research provides a platform to world-wide knowledge sharing, but the channels and possibilities are still limited. It is not always clearly defined how the process of publishing should take place. Information systems architectures are intrinsically complex engineering products that can be defined graphically on various levels of abstractions and represented using different aspects of the system. For that reason enterprise architecture is not easy to comprehend for different actors involved. Graphical representations of different business scenarios are critical to understand how different aspects of the system descriptions are analysed in relation to each other and how requirements from different perspectives are perceived as a whole. The goal of this paper is to introduce the modelling method for visualization of the process of publication of BSc thesis into institutional repositories. Universities need to investigate undergraduate students’ publications of their graduate work (BSc thesis) to promote knowledge of university repositories. Two different modelling methods were used to visualize publishing process and two case studies at two different universities were made. The results indicated and motivated that SICM method had more semantic power to visualize business process in a more comprehensive way.

    Visualization for Open Access: A Case Study of Karlstad University and the University of Makerere in Uganda2018In: Information and Software Technologies: 24th International Conference, ICIST 2018, Vilnius, Lithuania, October 4–6, 2018, Proceedings / [ed] Robertas Damaševičius; Giedrė Vasiljevienė, Cham: Springer, 2018, Vol. 920, p. 187-197Conference paper (Refereed)
    Abstract [en]

    Open Access (OA) research provides a platform to world-wide knowledge sharing, but the channels and possibilities are still limited. It is not always clearly defined how the process of publishing should take place. Information systems architectures are intrinsically complex engineering products that can be defined graphically on various levels of abstractions and represented using different aspects of the system. For that reason enterprise architecture is not easy to comprehend for different actors involved. Graphical representations of different business scenarios are critical to understand how different aspects of the system descriptions are analysed in relation to each other and how requirements from different perspectives are perceived as a whole. The goal of this paper is to introduce the modelling method for visualization of the process of publication of BSc thesis into institutional repositories. Universities need to investigate undergraduate students’ publications of their graduate work (BSc thesis) to promote knowledge of university repositories. Two different modelling methods were used to visualize publishing process and two case studies at two different universities were made. The results indicated and motivated that SICM method had more semantic power to visualize business process in a more comprehensive way.

    Introducing Service-Orientation into System Analysis and Design2008In: Information Systems Analysis and Specifications: Proceedings of the 10th International Conference of Enterprise Information Systems, Setúbal: INSTICC Institute for Systems and Technologies of Information, Control and Communication , 2008, p. 189-194Conference paper (Refereed)
    Abstract [en]

    The conventional methods of information system analysis and design are not based on service-oriented paradigm that facilitates control of business process continuity and integrity. Service-oriented representations are more compre¬hensi¬ble for business experts as well as system designers. It is reasonable to conceptualize a business process in terms of service-oriented events, before the supporting technical system is designed. UML design primitives abstract from the concrete implemen¬tation artefacts and therefore they are difficult to comprehend for business analysis experts. The presented approach for service-oriented analysis is based just on three types of events: creation, reclassification and termination, which can also be used for the semantic integrity and consistency control. In this paper, the basic service-oriented constructs are defined. Semantics of these implementation neutral artefacts are analysed in terms of their associated counterparts that are used in object-oriented design.

    Modelling Patterns for Business Processes2019In: Proceedings of the 25th International Conference on Information and Software Technologies, ICIST / [ed] G. Vasiljeviené, R. Damasevicius, Switzerland: Springer, 2019, p. 161-172Conference paper (Refereed)
    Abstract [en]

    Abstract. Analysis patterns are the groups of elements that represent a common construction in business modelling. Patterns are established with the aim to define and visualize the fundamental requirements that arise during business process modelling. There are a lot of patterns that describe the behaviour of business processes. Patterns enable stakeholders to communicate more effectively, with greater conciseness and less ambiguity. The problem with the existing business process patterns is that these patterns leave aside the static aspects of business processes. It is not enough to provide patterns just for processes or actions, it is necessary to show how data is integrated into business processes. This integration is important for flexible business processes, where stakeholders have more freedom to handle the sequence of actions in order to accomplish a given goal. The lack of an integrated modelling approach creates problems in rethinking and changing business processes. It is necessary to have a modelling approach which enables to manage necessary changes in business processes and data. The patterns for business processes should support the integration of static (data) and dynamic aspects (interaction and state changes of data) of the system as well to provide possibilities to model alternative actions in business processes. The paper presents Semantically Integrated Conceptual Modelling method (SICM) and how the method is applied for two modelling patterns that enables integration of both static and dynamic aspects of the system.

    Crafting Requirements for Mobile and Pervasive Emergency Response based on Privacy and Security by Design Principles2013In: International Journal of Information Systems for Crisis Response and Management, ISSN 1937-9390, E-ISSN 1937-9420, Vol. 5, no 2, p. 1-18Article in journal (Refereed)
    Abstract [en]

    According to fundamental principles of the Privacy by Design approach, the consultation of privacy issues should be embedded into analysis and design of information systems, from the early stages of system planning to implementation. In this article, we extend this perspective towards Privacy and Security by Design. Exemplary focusing on mobile and pervasive emergency response, as a specific area of the emergency management domain, this article conveys how the early requirements elicitation can be supported by a semantically integrated conceptual modeling method. Presenting the results of the exemplary executed elicitation processes, it contributes a concrete set of security and privacy requirements for mobile and pervasive emergency response settings. By also taking into account conflicting security goals, this article provides a substantial grounding for the development and deployment of multilaterally secure pervasive ICT that effectively supports emergency management during and in the aftermath of critical response missions.
