The Contribution of Conceptual Independence to IT Infrastructure Flexibility:The Case of openEHR.
Tarenskeen, D. ; Wetering, R. van de ; Bakker, R.R. ; Brinkkemper, S.
2020, Article in monograph or in proceedings (Project: Hospital’s IT infrastructure capability and digital capabilities, pp. 233-244)In the Netherlands demands on IT support in healthcare organizations are increasing. New visions on healthcare focus on patient-centered healthcare, where mutual consultation among healthcare professionals in the network becomes a standard process. Recent governmental regulations prescribe that patients must be able to access personal health records. IT flexibility is needed to allow organizations to meet new demands. In this study, we focus on Conceptual Independence (CI) be-cause CI, as a design principle, can improve the adaptability of Information Systems (IS). Software with CI operates on flexible data models that are independent of the CI based application. Therefore, it is claimed that a standalone IS becomes more flexible with CI. We extend the claim by demonstrating that CI affects the flexibility of the entire IT infrastructure. We investigate which dimensions of IT flexibility are responsible for the improvement. Multi-case study research has been performed following a mixed-methods approach in 10 mental healthcare organizations. Five have implemented openEHR, a proxy for CI, and five have not. Data has been collected with a questionnaire of IT infrastructure flexibility and semi-structured interviews. The data synthesis shows a positive effect of CI on IT flexibility, as CI increases the adaptability of IS, transparency and standardization of the IT infrastructure.

2019, Article in monograph or in proceedings (HTTF 2019: Proceedings of the Halfway to the Future Symposium 2019)Mixed reality applications can enrich museum exhibits and make them more attractive to an audience of adolescents. However, in the design of such applications, we face a myriad of possibilities and little guidance on how to choose between (early) alternatives. In this paper, we explore the notion of experience blend -which could act as an aesthetic governing the design of mixed reality experiences. We present an effort to operationalize experience blend and illustrate its use in the design and evaluation of an application for an art museum. Stakeholders in the project assumed that in order to reach out to adolescents an exciting experience was needed, deviating from education and breaking with the hidden rules of the art-museum, our user study showed that adolescents favored a blended experience. This suggests experience blend may be a helpful aesthetic in the design of other mixed reality experiences.

Unintended effects of dependencies in source code on the flexibility of IT in organizations.
Tarenskeen, D. ; Bakker, R.R. ; Wetering, R. van de
2018, Article in monograph or in proceedings (FEDERATED CONFERENCE ON COMPUTER SCIENCE AND INFORMATION SYSTEMS / In FedCSIS (ed.), Project: Hospital’s IT infrastructure capability and digital capabilities, pp. 87-94)This study links business requirements and adaptability of existing software systems. Organizations expect flexibility of IT with regard to business requirements. We hypothesize that the flexibility of business requirements is difficult in IT systems, because of software dependencies in the way domain knowledge is implemented. In this paper, we, therefore, explore how Business requirements have been implemented in the source code of three open source healthcare systems. Outcomes suggest that a tight interdependency of business terminology and functionality in source code hides business requirements from view and thereby hinders IT flexibility on higher levels.

From Big Data Communities to Enterprising Villagers The Transformational Effect of a Designerly Approach Within a Research Project
Bakker, R.R. ; Hansma, M. ; Goor, J.B.W. van de
2018, Article / Letter to editor (Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering, vol. jaargang, iss. nr, (2018))Using a designerly approach in projects within a wide spectrum of disciplines is increasingly popular. This paper describes a case in where the 1:10:100 design approach is used in a social sciences project and explores the mutual learning that took place. It discusses the added value of using design artefacts (prototypes) in the process and to what level these can be seen as boundary objects. Among the project partners there are two teams of social scientists (German and Dutch) that were collecting data and worked with abstract thinking processes and a design team who concerned about usability and intervened with design tools. The prototypes in the project are reviewed as boundary objects on three levels: to create common ground, to sharpen focus and as window into the future. The learning mechanisms that occurred (reflection and transformation) shifted the focus in the project from mining data on behalf of a community database towards a tool in which enterprising villagers can show their qualities and entrepreneurship.

Applying Axiomatic design and Conceptual independence in the domain of IT systems.
Tarenskeen, D. ; Bakker, R.R.
2017, Article in monograph or in proceedings (In MATEC Web of Conferences 127, 01006 (2017))In this paper we explain why Axiomatic design has not been applied in large system of systems information technology architectures in health care organizations in the Netherlands. We have found in extensive case studies of IT systems that the Independence axiom could not be found in the existing Information systems. This causes great concern for the adaptability of systems. Although best practices in system engineering advice decoupling of system functionality, findings show that the Independence Axiom has not been applied to functional requirements. A number of difficulties was exposed to the researcher and IT architects, when they tried to identify and to demarcate functional requirements in existing systems. In IT systems a distinction is made between business and system functions and software engineers emphasize decoupling of system functions. That has resulted in a strong coupling of business information and technical application logic. This means Conceptual dependencies are often at the heart of the difficulties. Decoupling these dependencies in applications seems a candidate for ordering requirements in a way that keeps the functional requirements independent from each other. Conceptual independence signifies a complete decoupling of the concepts and relations of the Business domain from the technical functionality. The paper describes the difficulties when applying the Independence Axiom in the Information systems domain and argues that a combination of Conceptual independence and Axiomatic design is achievable. The authors adapt the Design matrix with Conceptual independence. We conclude that applying Conceptual independence is crucial when constructing IT systems based on Axiomatic design.

Applying the V Model and Axiomatic Design in the Domain of IT Architecture Practice
Bakker, R.R. ; Joosten, Hennie ; Tarenskeen, D.
2015, Article in monograph or in proceedings (Procedia CIRP, pp. 262-268)This paper applies and discusses the principles of Axiomatic Design for changing IT architecture in health care. It presents three case studies positioned in the field of Enterprise architecture that explore how IT architects, as professionals, manage change and re-design the structure of the IT systems in line with strategic goals. The research approach was to use a light modelling tool, Ampersand, for modelling the Enterprise architecture. Two types of models stand out: Type 1 Strategic IT models in which higher strategic goals are related to requirements for applications and Type 2 Technical management of systems models in which technical risks and risk of system failure in the current IT infrastructure were modelled. To bridge the views of different IT experts in the organization this work uses the customer domain, the functional domain and the physical domain from Axiomatic Design in an extended example in the paper. The V Model is used to bridge the models, and then it is extended with Axiomatic Design principles.

Design Patterns for Mixed-Method Research in HCI
Holwerda, R.N.A. ; Bennis, Arthur ; Zaad, L.J. ; Bakker, R.R. ; Craenmehr, Sabine ; Hoppenbrouwers, S.J.B.A. ; Lenior, Dick ; Jacobs, M. ; Turnhout, K.G. van ; Niels, Ralph
2014, Article in monograph or in proceedings (NordiCHI'14)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.
Family in Focus: On Design and Field Trial of the Dynamic Collage [DC]
Bakker, R.R. ; Turnhout, K.G. van ; Jeurens, J.
2014, Article in monograph or in proceedings (Chi Sparks 2014)In this paper we present the design and field trial of the Dynamic Collage. The Dynamic Collage was designed to facilitate and to stimulate participation of family members in the informal care of an elderly person. The Dynamic Collage enabled relatives to update their current activity by sending a photo to a digital collage at the elderly person's living space. The service is triggered when a family member visits the elderly person. The field trial revealed that all family members valued this type of communication and that they became more aware of informal care. This shows there are opportunities to support informal care in a broader circle than current practices allow. Apart from informal care, our design case contributes to the field of social awareness systems, which we will discuss in the paper.
Tradeoffs in Design Research: Development Oriented Triangulation
Turnhout, K.G. van ; Craenmehr, Sabine ; Holwerda, R.N.A. ; Menijn, Mike ; Zwart, J.P. ; Bakker, R.R.
2013, Article in monograph or in proceedings (Proceedings of the 27th International BCS Human Computer Interaction Conference)The Development Oriented Triangulation (DOT) framework in this paper can spark and focus the debate about mixed-method approaches in HCI. The framework can be used to classify HCI methods, create mixed-method designs, and to align research activities in multidisciplinary projects. The framework is generic enough to capture the diversity of research within the HCI community, while being specific enough to foster constructive debate about combinatorial opportunities and difficulties in mixed-method research in HCI. An analysis of 10 previously published academic HCI research papers showed the utility of the framework for describing a wide range of HCI papers and for raising methodological questions about mixed method approaches in HCI.
Triangulatie: een basis voor de onderzoeksleerlijn in ICT- en mediaonderwijs
Menijn, Mike ; Zwart, J.P. ; Bakker, R.R. ; Holwerda, R.N.A. ; Craenmehr, Sabine ; Turnhout, K.G. van
2013, Article in monograph or in proceedings (Proceedings van het NIOC congres 2013, pp. 277-286)In deze bijdrage aan het NIOC 2013 bespraken we kort het triangulatie raamwerk dat de basis vormt voor de onderzoeksleerlijn van de Informatica en Communicatie academie(ICA) van de Hogeschool van Arnhem & Nijmegen (HAN). We denken dat de multidisciplinaire onderzoekspraktijk van ICT- en mediaonderwijs vraagt om een benadering die de diversiteit van onderzoek viert en in perspectief plaats. Het gepresenteerde triangulatie raamwerk maakt het mogelijk om de samenhang te zien in een diverse set van onderzoeksmethoden die voor praktijkonderzoek gebruikt worden. Door dit raamwerk als basis voor de onderzoeksleerlijn te gebruiken, verwachten we dat studenten beter door de opleiding heen komen (waarin ze geconfronteerd worden met diverse vormen van onderzoek) en beter leren samenwerken met collega’s die andere vormen van onderzoek hebben aangeleerd.
Using ampersand in IT architecture.
Bakker, R.R. ; Tarenskeen, D. ; Joosten, S.
2013, Article in monograph or in proceedings (Paper presented at the 7th International Conference on Research and Practical Issues of Enterprise Information Systems CONFENIS)IT architects in practice have a difficult task in extending and adapting enterprise information systems. Mastering complexity is a priority. This is still more art than craftsmanship in spite of many years of academic research in IT architecture. We will explore by a series of case studies how to support IT architects in practice, with their work of improving the consistency and completeness of emerging architectures. In this process, IT architects should be capable of discussing conflicting, incomplete, highly abstract, or overly detailed requirements with stakeholders and developers, while keeping an overview of all priorities and constraints. In this research paper, we first discuss the research strategy, Design research combined with case study research, to address this question. Next, we discuss Ampersand and its tool, a rule-based modeling language, and an engine developed in high-level IT consultancy. Ampersand seems promising for flexible modeling of IT architecture, and its rule engine can help IT architects manage consistency between requirements and IT solutions. An empirical exploration in developing the IT architecture for a new specialized child oncology hospital is used to check the premises of our research and the usefulness of Ampersand in this context. The conclusions of this exploration have led to hypotheses for testing in further research. The hypotheses concern applying the Ampersand approach to effectively support IT architects’ work.

UX in the Wild: on Experience Blend & Embedded Media Design
Turnhout, K.G. van ; Leer, S. ; Ruis, Emiel ; Zaad, L.J. ; Bakker, R.R.
2012, Article in monograph or in proceedings (The Web and Beyond 2012)The internet is becoming a tightly interwoven part of our everyday lives. There is a growing market for web services which augment the daily life of users trough products with an internet connection. We call these real world extensions of the web embedded media. In the last couple of years we explored embedded media design through student projects with real world clients. We learned that the UX difficulty of embedded media design is to mix, enforce and augment existing user experiences. We’ve tried to capture this challenge in the intuitive notion of experience blend. In this paper we use examples from our project work to introduce this notion of experience blend.
Interfacing Between Social Media, Business Processes and Users : A Design Case Study
Turnhout, K.G. van ; Holwerda, R.N.A. ; Schuszler, P. ; Tijsma, Lars ; Bakker, R.R.
2011, Article in monograph or in proceedings (Proceedings - Chi Sparks)In this paper, we will argue that developments in social media in the past few years open up an opportunity space for developing "integration software". Such software supports company specific use cases, while the software expands on existing social media infrastructure through web API's. We have explored this opportunity space for social media integration in companies with a conceptual design project. Seven groups of students designed and built "integration software" for two different companies. In this paper we present the three most interesting student concepts and identify challenges and opportunities for building "integration software".
