Dynamic stakeholder interaction analysis: Innovative smart living design cases

In order to become more innovative, companies that operate in the Smart Living domain increasingly initiate and participate in networked business environments that transcend industry boundaries. Inter-organizational collaboration is often characterized by conflicting strategic interests and incoherent operational business processes and procedures. Although many scholars and practitioners use stakeholder analysis to gain insight into the actors’ relationships and interactions, existing literature on stakeholder analysis focuses mainly on high-level strategic analysis, often limited to a conceptual and static understanding of stakeholder interests. In this paper, it is argued that a ‘true’ understanding of stakeholders can be achieved by looking at their interactions and interdependencies at a more detailed level. This study uses a conceptual framework from the service innovation and business model domain, the VIP framework, to extend stakeholder analysis by including an analysis of their dynamic interactions and processes. The qualitative evaluation of the framework’s application in illustrative design cases shows that this extension provides additional insights into stakeholders, and their potential operational conflicts and critical dependencies. By making these conflicts and interdependencies explicit, products and services are potentially easier to implement and commercialize.     

Integrated Vehicle Configuration System—Connecting the domains of mass customization

Configuration design for mass customized vehicles necessitates the coordination of customer requirements, product characteristics, production processes, and logistics networks, in order to achieve rapid response to customer orders. Existing product configurators are mainly used as sales tools, and fail to account for the requirements of the entire customer order fulfillment process. In this regard, this paper proposes an Integrated Vehicle Configuration System (IVCS) to facilitate customer order processing based on information from multiple domains in a mass customization environment. An IVCS business model is proposed to incorporate the decision factors for configuration design related to different planning stages. The business model is supported by a comprehensive ontology framework, which enhances communications between different stakeholders involved in the order fulfillment process. The configuration approach is based on combinations of selective and generative rules and can be integrated with existing ERP systems. It also provides mechanisms to handle configuration rules that allow users to convert soft preferences into product specifications, bill-of-materials, and, furthermore, into logistics configurations. An example of a computerized configuration system showcases the process from customer engineering to design and production.     

An empirical approach toward the resolution of conflicts in goal-oriented models

One significant problem requirements engineers have to cope with is the management of unclear requirements, ambiguities, and conflicts that may arise between stakeholders. Such issues may be desirable since they may allow for further elicitation of requirements that would have been missed otherwise. Goal models capture the objectives and other intentions of different stakeholders, together with their relationships. They can be used to refine unclear requirements and to detect conflicts and ambiguities early during model validation. However, resolving such ambiguities and conflicts is key for the successful implementation of the goal models. In this paper, we propose a novel approach to validate models in the Goal-oriented Requirement Language and resolve conflicts between the perspectives of intervening stakeholders (and especially between stakeholders of a given group). Our approach is based on a statistical analysis of empirical data that we collect from surveys designed for each group of stakeholders. We apply concept analysis in order to fix goal-model artifacts that are subject to conflict. We illustrate our approach using a case study of a goal model describing the involvement of undergraduate students in university research activities.     

Design principles for process modelling in enterprise application integration

There is a growing need for Enterprise Application Integration (EAI) technologies, which align the applications of an organisation to its business processes. Such technologies require an adequate methodological support so that well-structured and easily understandable models can be constructed. In this paper, such a methodological support is proposed by introducing principles for the design, validation and presentation of process models and associated data models. By applying these principles, we obtain different views of the models, and thereby facilitate the use of common models for different stakeholders, e.g. business managers, designers and operators.     

Object-oriented business process modeling and simulation:: A discrete event system specification framework

In this study, we suggest that the Discrete Event System Specification (DEVS) framework, derived from engineering research, provides a useful Object-Oriented Modeling and Simulation (OOMS) approach for developing, simulating and evaluating complex business process models. A survey of other OOMS approaches to business process modeling, and their evaluation with regard to model representation, manipulation and implementation, suggests that there are some limitations which could be addressed by DEVS. We conducted a case study of a business process in a “real world” setting to explore some of the issues involved in implementing the DEVS framework.Our findings suggest that DEVS provides a robust framework for model representation based on its concept of atomic models and its ability to represent higher-level models that are closed under coupling. It also provides considerable model manipulation capabilities through a System Entity Structure (SES), the pruning of the SES by inclusion of instances of models which correspond to processing alternatives, and a relatively easy transition from conceptual models to simulation models. Finally, our implementation of DEVS in a business situation contributes to the parent discipline by highlighting a number of methodological issues such as discrepancy resolution by identifying root causes, assumptions surfacing and re-examination, and an awareness of the political and cultural context of business process modeling. Our study suggests that IS research on developing OOMS approaches to business process modeling can derive considerable benefits by leveraging off DEVS-related research in engineering.     

Optima: a domain-specific model for prioritization and conflicts management in requirements engineering for services intermediaries

New business models are set up, thanks to Web technologies. In this work, we focus on services intermediary companies. They generate value through the (automatic) selection of third-party services and the (automatic) delivery of the combinations of these services to consumers. Such companies face the problem of deciding which services to select and deliver in order to maximize their profit. The two main paper objectives are (i) to design the generic business model of services intermediaries and (ii) to propose an optimization model. The latter enables to choose the consumer requirements that will be satisfied in order to maximize profit. This model ranks implementable solutions based on various financial aspects. They are related to cost and revenue information that is associated with the requirements. It can support the decision-making process that aims at selecting a profit-maximizing set of requirements for services intermediaries’ system-to-be. Indeed, the proposed model solves the conflicts between requirements and prioritizes the optional requirements. We argue for the relevance of the optimization model via an example and simulations.     

Synthesizing Service Composition Models on the Basis of Temporal Business Rules

Transformational approaches to generating design and implementation models from requirements can bring effectiveness and quality to software development. In this paper we present a framework and associated techniques to generate the process model of a service composition from a set of temporal business rules. Dedicated techniques including path-finding,branching structure identification and parallel structure identification are used for semi-automatically synthesizing the process model from the semantics-equivalent Finite State Automata of the rules. These process models naturally satisfy the prescribed behavioral constraints of the rules. With the domain knowledge encoded in the temporal business rules,an executable service composition program,e.g.,a BPEL program,can be further generated from the process models. A running example in the e-business domain is used for illustrating our approach throughout this paper.     

Business process model repositories - Framework and survey

Context

Large organizations often run hundreds or even thousands of different business processes. Managing such large collections of business process models is a challenging task. Software can assist in performing that task, by supporting common management functions such as storage, search and version management of models. It can also provide advanced functions that are specific for managing collections of process models, such as managing the consistency of public and private processes. Software that supports the management of large collections of business process models is called: business process model repository software.

Objective

This paper contributes to the development of business process model repositories, by analyzing the state of the art.

Method

To perform the analysis a literature survey and a comparison of existing (business process model) repository technology is performed.

Result

The results of the state of the art analysis are twofold. First, a framework for business process model repositories is presented, which consists of a management model and a reference architecture. The management model lists the functionality that can be provided and the reference architecture presents the components that provide that functionality. Second, an analysis is presented of the extent to which existing business process model repositories implement the functionality from the framework.

Conclusion

The results presented in the paper are valuable as a comprehensive overview of business process model repository functionality. In addition they form a basis for a future research agenda. We conclude that existing repositories focus on traditional functionality rather than exploiting the full potential of information management tools, thus we show that there is a strong basis for further research.     

A participative end-user method for multi-perspective business process elicitation and improvement

A business process can be characterized by multiple perspectives (intentional, organizational, operational, functional, interactional, informational, etc). Business process modeling must allow different stakeholders to analyze and represent process models according to these different perspectives. This representation is traditionally built using classical data acquisition methods together with a process representation language such as BPMN or UML. These techniques and specialized languages can easily become hard, complex and time consuming. In this paper, we propose ISEA, a participative end-user modeling approach that allows the stakeholders in a business process to collaborate together in a simple way to communicate and improve the business process elicitation in an accurate and understandable manner. Our approach covers the organizational perspective of business processes, exploits the information compiled during the elicitation of the organizational perspective and touches lightly an interactional perspective allowing users to create customized interface sketches to test the user interface navigability and the coherence within the processes. Thus, ISEA can be seen as a participative end-user modeling approach for business process elicitation and improvement.     

Thresholds for error probability measures of business process models

The quality of conceptual business process models is highly relevant for the design of corresponding information systems. In particular, a precise measurement of model characteristics can be beneficial from a business perspective, helping to save costs thanks to early error detection. This is just as true from a software engineering point of view. In this latter case, models facilitate stakeholder communication and software system design. Research has investigated several proposals as regards measures for business process models, from a rather correlational perspective. This is helpful for understanding, for example size and complexity as general driving forces of error probability. Yet, design decisions usually have to build on thresholds, which can reliably indicate that a certain counter-action has to be taken. This cannot be achieved only by providing measures; it requires a systematic identification of effective and meaningful thresholds. In this paper, we derive thresholds for a set of structural measures for predicting errors in conceptual process models. To this end, we use a collection of 2000 business process models from practice as a means of determining thresholds, applying an adaptation of the ROC curve method. Furthermore, an extensive validation of the derived thresholds was conducted by using 429 EPC models from an Australian financial institution. Finally, significant thresholds were adapted to refine existing modeling guidelines in a quantitative way.     

Modelling mobile app requirements for semantic traceability

The paper presents a modelling method aimed to support the definition and elicitation of requirements for mobile apps through an approach that enables semantic traceability for the requirements representation. Business process-centricity is employed in order to capture requirements in a knowledge structure that retains procedural knowledge from stakeholders and can be traversed by semantic queries in order to trace domain-specific contextual information for the modelled requirements. Consequently, instead of having requirements represented as natural language items that are documented by diagrammatic models, the communication channels are switched: semantically interlinked conceptual models become the requirements representation, while free text can be used for requirements annotations/metadata. Thus, the method establishes a knowledge externalization channel between business stakeholders and app developers, also tackling the Twin Peaks bridging challenge (between requirements and early designs). The method is presented using its modelling procedure as a guiding thread, with each step illustrated by case-based samples of the modelling language and auxiliary functionality. The design work is encompassed by an existing metamodelling framework and introduces a taxonomy for modelling relations, since the metamodel is the key enabler for the goal of semantic traceability. The research was driven by the ComVantage EU research project, concerned with mobile app support for collaborative business process execution. Therefore, the project provides context for the illustrating examples; however, generalization possibilities beyond the project scope will also be discussed, with respect to both motivation and outcome.     

RASES: A database supported framework for structured model base management

Structured management of model base has placed demands on some kind of computer based frameworks with highly structured formalisms. This paper proposes a new framework, called the relational algebraic system entity structure (RASES), which is based on the system entity structure (SES) formalism and the relational algebra (RA) formalism. These formalisms provide a conceptual basis for the structured model base management. Within the framework, structural knowledge of a system is represented in a hierarchical structure and saved in a database. Furthermore, several operations can be formulated in terms of relational algebra which can be coded in a standard query language such as the SQL. The framework can be easily implemented on, and fully utilize the functionality of, relational database management system (RDBMS). With the help of the implemented framework, simulation models can be systematically synthesized from the models in the model base through the following processes. First, a family of hierarchical structures of a system is organized in the form of entity structure by the entity structuring process. Then, candidate models of the system which meet design objectives are synthesized from the entity structure through the pruning process. Finally, designers can conduct appropriate experiment with the models for design verification and performance measure.     

An approach for business process model registration based on ISO/IEC 19763-5

To facilitate business collaboration and interoperation among enterprises, it is critical to discover and reuse appropriate business processes modeled in different languages and stored in different repositories. However, the formats of business process models are very different, which makes it a challenge to fuse them in a unified way without changing their original representations and semantics. To solve this problem, this paper uses semantic interoperability technique which is able to transform heterogeneous process models into uniform registered items. Based on the general and unambiguous metamodel for process model registration (PMR for short) in ISO/IEC 19763-5 that we proposed before, in this article, we provide a generic process model registration framework for registering heterogeneous business process models to facilitate semantic discovery of business processes across enterprises, and promote process interoperation and business collaboration. Considering that Event-driven Process Chain (EPC) is a popular process model widely used in the industry, we focus on the mapping rules and related specific transformation algorithms from EPC to PMR as an instantiation of our framework and develop an automatic process model registration tool for EPC. Moreover, we conduct a series of experiments to verify the correctness and efficiency of our proposed framework by leveraging the real data set of 604 EPCs from SAP.     

Task-specific visual cues for improving process model understanding

ContextBusiness process models support various stakeholders in managing business processes and designing process-aware information systems. In order to make effective use of these models, they have to be readily understandable.ObjectivePrior research has emphasized the potential of visual cues to highlight relevant matters in models such that stakeholders can use them more efficiently. What prior research does not explain is in how far visual cues can be customized to specific understanding tasks and how this influences cognition.MethodIn this paper, we address these questions with an experimental research design, in which we use eye-tracking equipment to capture how process experts use models to answer comprehension questions. As a treatment, we designed two manipulations of the secondary notation, namely coloring and layout, to direct attention to the elements relevant for the specific tasks.ResultsOur results indicate that both manipulations improve both eye-tracking-based measures and performance measures such as duration and efficiency, with color having the stronger effect.ConclusionsOur findings lay the foundation for novel features of process modeling tools that provide modifications of secondary notation in response to specific user queries. More generally, our research emphasizes the importance of the relevant region associated with a particular model understanding task.     

Ten years of visualization of business process models: A systematic literature review

Business process modeling is an essential task in business process management. Process models that are comprehensively understood by business stakeholders allow organizations to profit from this field. In this work, we report what is being investigated in the topic “visualization of business process models”, since visualization is known as improving perception and comprehension of structures and patterns in datasets. We performed a systematic literature review through which we selected and analyzed 46 papers from two points of view. Firstly, we observed the similarities between the papers regarding their main scope. From this observation we classified the papers into six categories: “Augmentation of existing elements”, “Creation of new elements”, “Exploration of the 3D space”, “Information visualization”, “Visual feedback concerning problems detected in process models” and “Perspectives”. The less explored categories and which could represent research challenges for further exploration are “Visual feedback” and “Information visualization”. Secondly, we analyzed the papers based on a well-known visualization analysis framework, which allowed us to obtain a high-level point of view of the proposals presented in the literature and could identify that few authors explore user interaction features in their works. Besides that, we also found that exactly half of the papers base their proposals on BPMN and present results from evaluation or validation. Since BPMN is an ISO standard and there are many tools based on BPMN, there should be more research intending to improve the knowledge around this topic. We expect that our results inspire researchers for further work aiming at bringing forward the field of business process model visualization, to have the advantages of information visualization helping the tasks of business process modeling and management.     

Literature review of reuse in business process modeling

Business process models play an important role in the analysis and improvement of the performance of an enterprise. Evidently, the quality of a business process model has a direct effect on the business performance. This evidence has motivated both the academic and industrial communities to look for suitable methods for creating good quality business process models. In particular, there is a wide agreement that reuse can accelerate the design process and produce high quality solutions by adopting best practices and agreed-up-on solutions. However, faced with various types of reusable artifacts, business process designers need a set of criteria to determine which type would suit best their needs and design context. To assist designers in their choice, we first present a set of criteria influencing the design phase in terms of effort required and the quality of the resulting model. Secondly, we use this set of criteria to present a state of the art on the most significant reusable design artifacts.
