  Symptom checkers are software tools that allow users to submit a set of symptoms and receive advice related to them in the form of a diagnosis list, health information or triage. The heterogeneity of their potential users and the number of different components in their user interfaces can make testing with end-users unaffordable. We designed and executed a two-phase method to test the respiratory diseases module of the symptom checker Erdusyk. Phase I consisted of an online test with a large sample of users (n = 53). In Phase I, users evaluated the system remotely and completed a questionnaire based on the Technology Acceptance Model. Principal Component Analysis was used to correlate each section of the interface with the questionnaire responses, thus identifying which areas of the user interface presented significant contributions to the technology acceptance. In the second phase, the think-aloud procedure was executed with a small number of samples (n = 15), focusing on the areas with significant contributions to analyze the reasons for such contributions. Our method was used effectively to optimize the testing of symptom checker user interfaces. The method allowed kept the cost of testing at reasonable levels by restricting the use of the think-aloud procedure while still assuring a high amount of coverage. The main barriers detected in Erdusyk were related to problems understanding time repetition patterns, the selection of levels in scales to record intensities, navigation, the quantification of some symptom attributes, and the characteristics of the symptoms.

Lecture Notes in Computer Science.  ISSN 0302-9743.  10513, s 364- 373 . doi: 10.1007/978-3-319-67744-6_24 Show summary

  Demands for technological solutions to address the variety of problems in healthcare have increased. The design of eHealth is challenging due to e.g. the complexity of the domain and the multitude of stakeholders involved. We describe a workshop method based on Critical Incidents that can be used to reflect on, and critically analyze, different experiences and practices in healthcare. We propose the workshop format, which was used during a conference and found very helpful by the participants to identify possible implications for eHealth design, that can be applied in future projects. This new format shows promise to evaluate eHealth designs, to learn from patients’ real stories and case studies through retrospective meta-analyses, and to inform design through joint reflection of understandings about users’ needs and issues for designers.

  To enhance operational sustainability of services, service quality is needed to be monitored. Expected and experienced service can be compared to evaluate service quality. Service performances involves a sequence of events with many details; describing performances can therefore be challenging. Several methods and tools supporting description of service performances have been introduced. However, there has been little attention on which methods or tools are used in practice and what are the challenges. We conducted an online-based survey with fifty-four people working in service design and development in Norway. We found that there is a need for standardised and consistent methods that can illustrate different communication channels in service delivery processes and support description of both the details and whole process in an intuitive manner. Having a standardised software tool and the guideline, which support illustration of service delivery processes, will be a possible way to overcome the challenges.

  This paper discusses components of service in healthcare. Four components of a service (service customer, service worker, service setting and service process) were introduced. Yet these components have not been explored in healthcare cases. We identified the key components through our case study with out-patient histories, involving electronic health record systems. Based on our analysis we propose a set of components to be considered for designing stakeholder-centred services in healthcare. The result of this study might be useful to the health informatics researchers to better understand the service interactions in today’s healthcare in a more analytic and holistic way by taking the service engineering perspective, at the same time to the service engineering or design researchers to have a deeper insight of the services in healthcare and the components to be considered when designing the services.

  Studies have described the opportunities and challenges of applying service design techniques to health services, but empirical evidence on how such techniques can be implemented in the context of eHealth services is still lacking. This paper presents how a service design thinking approach can be applied for specification of an existing and new eHealth service by supporting evaluation of the current service and facilitating suggestions for the future service. We propose Service Journey Modelling Language and Service Journey Cards to engage stakeholders in the design of eHealth services.

  This paper presents the results from a qualitative study that examined how the transitions from service concepts through specification to implementation occur. Twelve people working in service organisations and service design agencies in Norway, were interviewed about their experience and opinions. The interviews were transcribed and analysed using NVivo10, and thematic analysis was applied to confirm the results from NVivo10. We found that there was a big communication gap between service concepts and implementation especially inside the service organisations. To bridge this gap, we propose two solutions: strengthening service design thinking inside the service organisations and having better methods and tools that support rigorous service specification. The results of the study can be useful to service organisations who wish to have deeper insight into the transition process, in addition to service designers and researchers to have a better understanding of the service design and development challenges inside service organisations.

  Design thinking (DT) is regarded as a system of three overlapping spaces—viability, desirability, and feasibility—where innovation increases when all three perspectives are addressed. Understanding how innovation within teams can be supported by DT methods and tools captivates the interest of business communities. This paper aims to examine how DT methods and tools foster innovation in teams. A case study approach, based on two workshops, examined three DT methods with a software tool. The findings support the use of DT methods and tools as a way of incubating ideas and creating innovative solutions within teams when team collaboration and software limitations are balanced. The paper proposes guidelines for utilizing DT methods and tools in innovation projects.

  Business process management aims to align the business processes of an organisation with customers’ needs. Such alignment is of particular importance for services and requires a good understanding of the interactions among the actors involved. Although several process modelling languages and a service design technique called ‘service blueprint’ provide good support for modelling of service delivery processes, the actual execution of service and networked interactions among actors seem to have not been sufficiently considered. To overcome these limitations, we developed the Service Journey Modelling Language. Each version of the language has been evaluated, and the results were used as input for the next version. Results from our case studies show that our language might supplement the management of business processes for services by aligning business processes with customer perspectives and by supporting depiction of the actual service journeys with networked interactions of involved actors using appropriate visual representations.

  The increasing interest in service design implies the need for more formal approaches to the analysis, conceptualization, and implementation of services. In particular, this is critical when multiple actors, such as designers, developers, and managers are to apply a service design approach for a customer centric transformation of the organization and its service offerings. In this paper, we present key components of a formal language for the modelling of customer journeys. The language is developed, in particular, to support customer journey analysis and design; its formal character is meant to facilitate an unambiguous communication of a customer journey throughout a service organization, and to bridge the current gap between fuzzy front-end service design and service implementation. Application of the language is illustrated through case studies from a large web-based service provider and a power company.

  Business process management aims to align the business processes of an organisation with customers' needs. Doing this is of particular importance for services and requires a good understanding of interactions among the stakeholders involved in service provision and consumption. Several business modelling languages have been proposed, such as Business Process Modelling Notation (BPMN), Business Process Executable Language (BPEL) and Web Services Choreography Description Language (WS-CDL). Although these languages provide good support for process modelling, their consideration of the customer’s point of view seems to be insufficient. On the other hand, visualisations of customer journeys for the purpose of conceptualisation of new services have been successfully used in the area of service design. Our hypothesis is that a visual language presenting the customer journey through a service might be useful for aligning business processes of service providers with customers' needs and, in turn, contribute to the delivery of better services. We propose Service Journey Modelling Language (SJML) and report our first experience with it.

  Changing dietary habits is one of the most challenging tasks of diabetes self-management. Mobile terminals are increasingly used as platforms for tools to support diet management and health promotion. We present literature describing mobile terminal-based support tools for management of diabetes focused on diet. We also propose a summary of key success factors for designing such tools and discuss recommendations for future research.

  The main idea of the VISUAL project is to develop a visual language supported by methods and tools for service design. The language will enable specification, implementation and maintenance of new and existing services through a common terminology and extensive use of visualization. This will ease the cross-departmental communication and provide a common language for customer experience.

  Although the high importance of service in today's economy, the de-gree of customers' satisfaction about delivered service can be lower than ex-pected. Improving customers' satisfaction requires understanding of the reason of the distance answering following questions; What cause the distance? Is there any problem in the service process, the process of planning and designing services? We propose a visual language as a mean for improving service design process. The language will be developed and evaluated in collaboration with three industrial partner companies. Case studies will be conducted in iterative manner.
