Gamification as a topic is getting increasing attention within organizations as a method of organizing and structuring business processes. Gamification is about using game elements in a non-game context with the intention to effectuate a sustainable behavior change. In this paper we introduce Persuasive and Motivational Design (PMD) for information system design methods. This method applies Game Psychology as a safeguard to guarantee sustainable behavior changes that are required for a successful introduction of solutions designed with PMD. PMD has been used for over two years in a course program and has been tested in a business setting. The impact (such as the experiences during the validation of PMD in a case study) will be addressed in an upcoming paper.

In this paper we discuss the use and challenges of identifying communities with shared semantics in Enterprise Modeling. People tend to understand modeling meta-concepts (i.e., a modeling language’s constructs or types) in a certain way and can be grouped by this understanding. Having an insight into the typical communities and their composition (e.g., what kind of people constitute a semantic community) would make it easier to predict how a conceptual modeler with a certain background will generally understand the meta-concepts he uses, which is useful for e.g., validating model semantics and improving the efficiency of the modeling process itself. We demonstrate the use of psychometric data from two studies involving experienced (enterprise) modeling practitioners and computing science students to find such communities, discuss the challenge that arises in finding common real-world factors shared between their members to identify them by and conclude that the common (often implicit) grouping properties such as similar background, focus and modeling language are not supported by empirical data.

In this paper we explore the subject of question asking as an inherent driver of enterprise modelling sessions, within the narrower context of the ‘dialogue game’ approach to collaborative modelling. We explain the context, but mostly report on matters directly concerning question asking and answer pre-structuring as a central issue in an ongoing effort aiming for the practice-oriented development of a series of dialogue games for collaborative modelling. We believe that our findings can be relevant and helpful to anyone concerned with planning, executing or facilitating collaborative modelling sessions, in particular when involving stakeholders untrained in systems thinking and modelling.

However, SD shows a lack of means for discovering and expressing precise, language-based concepts in domains. Therefore, we choose to use Object-Role Mod- eling (ORM) to add high quality formal conceptualization to SD modeling and Petri Nets (PNs) to bridge the gap between static ORM and Dynamic, flow-like aspects of SD. To achieve the integration of these methods, we take a step by step approach where we first identify the conceptual link between SD and ORM, then the key concepts used in these methods, which we later use to derive mappings, transition statements and el- ements. This helps us to better understand the underlying concepts, the connections between the model structure, and behavior in a sequential manner. 3rd International Workshop EMISA 2009, 10 september 2009

In this paper we discuss mixed-method research in HCI. We report on an empirical literature study of the NordiCHI 2012 proceedings which aimed to uncover and describe common mixed-method approaches, and to identify good practices for mixed-methods research in HCI. We present our results as mixed-method research design patterns, which can be used to design, discuss and evaluate mixed-method research. Three dominant patterns are identified and fully described and three additional pattern candidates are proposed. With our pattern descriptions we aim to lay a foundation for a more thoughtful application of, and a stronger discourse about, mixed-method approaches in HCI.

Adaptive Case Management is used to manage unpredictable processes. These processes are mostly knowledge oriented and different roles need to collaborate to carefully plan the next steps during the execution of a case. These next steps cannot always be planned ahead, but depend on events and changes and differ for each instance. During the execution period the actual model of the run time planning, of a particular instance of a case, is made. For different roles to easily plan the correct next steps, it is important that such a case can be conceptualized and communicated. In this paper we suggest the idea of using game elements, or Gamification, to enhance the planning process during the execution of a case. With the use of Gamification we hope to make this process more recognizable for people and create better involvement by engaging the familiarity of games. The use of role-playing games is already being used for workshops and requirements elicitation. By building on existing work in Adaptive Case Management and Gamification we show that most games and the planning process of a case are in some respects similar. More in particular, we will discuss how we can learn from games to improve the team play during the planning process of a case. Finally this idea will be explained through an example of a planning process for an unpredictable case.

This paper reports on a case study of abstract reasoning in a real collaborative modeling setting. The study was conducted according to the behavioral observation principles of human ethology. Our findings indicate a relation between an individual's executive functioning and his ability to do abstract reasoning. Furthermore, we find individual differences in these abilities, and our results suggest that lack of certain skills pushes a session back to its initial phase until a shared conception of what is being modeled is achieved. These findings further our understanding of the process of collaborative modeling, how the qualities and behaviors of an individual modeler influence the interactive modeling process and its final outcomes.

Onbekend.Economies around the globe have evolved into being largely service-oriented economies. Consumers no longer just want a printer or a car, they rather ask for a printing service or a mobility service. In addition, service-oriented organizations increasingly exploit new devices, technologies and infrastructures. Agility is the ability to deal with such changing requirements and environments. Agile ways of working embrace change as a positive force and harness it to the organizations competitive advantage. The approach described in this book focuses on the notion of a service as a piece of functionality that offers value to its customers. Instead of solely looking at agility in the context of system or software development, agility is approached in a broader context. The authors illustrate three kinds of agility that can be found in an agile enterprise: business, process and system agility. These three types of agility reinforce each other and establish the foundation for the agile enterprise. Architecture, patterns, models, and all of the best practices in system development contribute to agile service development and building agile applications. This book addresses two audiences. On the one hand, it aims at agile and architecture practitioners who are looking for more agile ways of working in designing and building business services or who are interested in extending and improving their agile methods by using models and model-based architectures. On the other hand, it addresses students of (enterprise) architecture and software development or service science courses, both in computer science and in business administration.

In this paper, we describe our study on the relation between formation of abstractions and aspects of executive control in the context of process modeling. We have observed and recorded three business process modeling projects in different companies. We report on the findings resulting from the analysis of the first project. We find evidence that certain traits related to high-quality abstraction formation contribute to more structured modeling performance. Through our analysis we gain more insight in the cognitive mechanisms involved in modeling, which provides us with another step towards design of effective modeling support.

In this chapter, we address the issue of communication with stakeholders in agile development projects. Our approach pivots round ‘communication situations’ that occur in such communication; we do not cover all communication that may occur in projects but focus mainly on the model-oriented kind and on situations in which stakeholders (apart from developers) play an important role. We provide some context and background but also concrete ways of analysing and guiding communication situations using some dedicated instruments. We illustrate this with examples from practice.

Agile software development has evolved into an increasingly mature software development approach and has been applied successfully in many software vendors’ development departments. In this position paper, we address the broader agile service development. Based on method engineering principles we define a framework that conceptualizes an operational way of working for the development of services, emphatically taking into account agility. As a first level of agility, the framework contains situational project factors that influence the choice of method fragments; secondly, increased agility is proposed by describing and operationalizing these method fragments not as imperative steps or activities, but instead by means of sets of minimally specified, declarative rules that determine the context and constraints within which goals are to be reached. This approach borrows concepts from rules management, organizational patterns, and game design theory.

In this paper we discuss our preliminary work on clarifying the conceptual landscape of Enterprise Architecture. We do so to aid in the integration of conceptual models originating from different communities (of language users, concerns, viewpoints etc.). We propose that discovering the basic ontological structure used by these communities is necessary for the effective integration of models, and that different communities have a distinguishable different central understanding of some categories in their ontology. Our initial results include the description and categorization analysis of several languages and methods used in EA (as used by their creators), which suggest a prototype structure reflecting a community’s focus.

The objective of an energy management strategy for fuel cell hybrid propulsion systems is to minimize the fuel needed to provide the required power demand. This minimization is defined as an optimization problem. Methods such as dynamic programming numerically solve this optimization problem. Strategies such as the equivalent consumption minimization strategy derive an analytical solution based on low-order models that approximate fuel cell stack and battery behavior. This paper presents an analytical solution based on models of the fuel cell system and battery close to physics. Apart from an analytical solution, this solution provides a fundamental understanding of the energy management problem. Because the solution is analytic and does not need a priori knowledge, the computation time is limited, and real-time implementation is possible. The solution presented is validated against existing optimizing energy management strategies in both simulations and experiments. For simulations, a midsize distribution truck is chosen. Experiments are carried out on a 10-kW scale test facility that comprises a fuel cell system, a battery, a motor with load, and an electronic load. In both simulations and measurements, the solution presented in this paper performs best compared to the equivalent consumption minimization strategy and a range-extender strategy, although the differences are within 3%. In the simulations, the solution presented approaches a minimum in fuel consumption, derived offline using dynamic programming, within 1%.

We report on the development of a prototype dialogue game for FCO-IM. Dialogue games are systems for executing controlled conversations. As part of an ongoing effort to analyze and support collaborative modeling processes by means of dialogue games, we created a dialogue game prototype for essential parts of the FCO-IM modeling process. The project was exploratory in nature, but results suggest that eventually it should be possible to develop dialogue games that could effectively support fact-based conceptual modeling efforts. In addition, work on such games enhances our insights in the FCO-IM modeling process, and leads to improvements and extensions of its operational guidelines.

This paper concerns the application of a gaming approach to the validation of ArchiMate models, with the aim of enhancing validation, by non-architects, beyond mere reading of the model. The game offers a guided process for systematic exploration of ArchiMate models, and for systematically raising questions about them. The development process and the design principles behind the game are discussed, as well as the information transformation involved in creating a model-specific game from an ArchiMate model. The game has been evaluated through application in a small real life case. We discuss the influence of our approach to model understanding by the players, and the conceptual merits and flaws of the game.

Collaborative modeling uses and produces modeling artifacts whose quality can help us gauge the effectiveness and efficiency of the modeling process. Such artifacts include the modeling language, the modeling procedure, the products and the support tool or medium. To effectively assess the quality of any collaborative modeling process, the (inter-) dependencies of these artifacts and their effect on modeling process quality need to be analyzed. Although a number of research studies have assessed and measured the quality of collaborative processes, no formal (causal) model has been developed to assess the quality of the collaborative modeling process through a combination of modeling artifacts. This paper develops a Collaborative Modeling Process Quality (CMPQ) construct for assessing the quality of collaborative modeling. A modeling session involving 107 students was used to validate and measure the quality constructs in the model.

Understanding modelling behaviour is an important step towards situated modelling support, especially when aiming to actively involve the domain expert in modelling without expert interventions. In search for a hypothesis on which modelling acts humans exhibit naturally, this paper presents an exploratory study into the modelling approaches intuitively taken by people trained in modelling as opposed to people not trained in modelling. Participants were asked to create a concept map of either a familiar or unfamiliar knowledge domain.

This paper reports on a next step in a line of research taking the perspective that modelling as an activity is a ‘constrained conversation’. We focus on concrete communication situations in context of (enterprise) modelling sessions, with special attention to the involvement of ‘novice modellers’. We present some theoretical notions that are helpful in understanding why modelling performed by/with novice modellers can usually be best broken down in sub-tasks, and how such decomposed tasks can be analysed and structured to match the limited skills of (novice) modellers. The generic aspects presented are then linked to generic types of questions and answers that are both drivers and constraints for the ‘dialogue games’ played in conversations-for-modelling. We also present and illustrate an instrument for analysis, the ‘Focused Conceptualisation’ (FoCon), which can help identify, evaluate and create dialogue games for model-oriented communication situations; we discuss three working examples of the use of FoCons.
