Design and demonstration of an engineering method for service support systems

An integrated and simultaneous design that considers products, services, and information systems is essential due to the mutual influences among each of the three components. This is particularly important in technical customer services (TCS), as the engineering process combines complex high-tech products with diverse types of services. However, to-date no explicit guidance on the integration of information systems into the product service systems engineering process exists. Thus, we propose a method to design service support systems simultaneously. For designing the method, a design science research approach was applied. We demonstrated the applicability of our method by designing and implementing a two-tier service system in a real-world scenario in the domain of TCS: A Virtual Reality-based Training System for training purposes along with a Smart Glasses-based Support System that guides the service technician at the point of service. By proposing and demonstrating our method, we enhance the body of knowledge in service systems engineering and design of IS. The practical contribution is given in additional guidance for designers of new products, services, and IS to master complexity and foster information support of technicians.     

Appropriate computer-mediated communication: An Australian indigenous information system case study

This article discusses ways to operationalise the concept of culturally appropriate computer-mediated communication, utilising information systems (IS) development methodologies and adopting a postmodern and postcolonial perspective. By way of illustration, it describes progress on the participative development of the Ieramugadu Cultural Information System. This project is designed to develop and evaluate innovative procedures for elicitation, analysis, storage and communication of indigenous cultural heritage information. It is investigating culturally appropriate IS design techniques, multimedia approaches and ways to ensure protection of secret/sacred information. Ethical issues are foregrounded.     

Client-Led Information System Creation (CLIC): navigating the gap

Abstract.  This paper offers a new framework to facilitate an interpretive approach to client-led information system development, referred to as CLIC (Client-Led Information System Creation). The challenge of moving seamlessly through a process of information systems (IS) design is still the subject of much research in the IS field. Attempts to address the difficulties of 'bridging the gap' between a client's business needs and an information system definition have hitherto not provided a coherent and practical approach. Rather than attempting to bridge the gap, this paper describes an approach to managing this gap by facilitating the clients' navigating through the information system design process (or inquiry process) in a coherent manner. The framework has been developed through practice, and the paper provides an example of navigating through the design phase taken from an Action Research field study in a major UK bank.

Identifying the causes of resistance to IS implementation: A change theory perspective

The major deterrents to successful IS (Information System) implementation include both technical and organizational issues. However, it is widely recognized that the more serious dimension of this problem is essentially behavioral in nature. This is because the introduction of any IS causes change in the organization; i.e to individuals, responsibilities, socio-political structure, etc. The purpose of this research effort is to investigate the relationship between organizational change and IS implementation. Towards this end, organizational change theories serve as the basis for assessing the causes of resistance to IS implementation.

Enterprise engineering and management at the crossroads

The article provides an overview of the challenges and the state of the art of the discipline of Enterprise Architecture (EA), with emphasis on the challenges and future development opportunities of the underlying Information System (IS), and its IT implementation, the Enterprise Information System (EIS). The first challenge is to overcome the narrowness of scope of present practice in IS and EA, and re-gain the coverage of the entire business on all levels of management, and a holistic and systemic coverage of the enterprise as an economic entity in its social and ecological environment. The second challenge is how to face the problems caused by complexity that limit the controllability and manageability of the enterprise as a system. The third challenge is connected with the complexity problem, and describes fundamental issues of sustainability and viability. Following from the third, the fourth challenge is to identify modes of survival for systems, and dynamic system architectures that evolve and are resilient to changes of the environment in which they live. The state of the art section provides pointers to possible radical changes to models, methodologies, theories and tools in EIS design and implementation, with the potential to solve these grand challenges.     

Assessing e‐commerce systems success: a respecification and validation of the DeLone and McLean model of IS success

Abstract. DeLone & McLean (2003) propose an updated information systems (IS) success model and suggest that it can be extended to investigating e‐commerce systems success. However, the updated IS success model has not been empirically validated in the context of e‐commerce. Further, the existing IS/e‐commerce success models have been subject to considerable debate on the ‘IS Use’ and ‘Perceived Usefulness’ constructs, and the nomological structure of the updated DeLone and McLean model is somewhat inconsistent with the IS acceptance and marketing literature. Based on the IS and marketing literature, this paper respecifies and validates a multidimensional model for assessing e‐commerce systems success. The validated model consists of six dimensions: Information Quality, System Quality, Service Quality, Perceived Value, User Satisfaction and Intention to Reuse. Structural equation modelling techniques were applied to data collected by questionnaire from 240 users of e‐commerce systems in Taiwan. The empirical evidence suggests that Intention to Reuse is affected by Perceived Value and User Satisfaction, which, in turn, are influenced by Information Quality, System Quality and Service Quality. The nomological structure of the respecified e‐commerce systems success model is concurred with that of the technology acceptance model (TAM) in the IS field and the consumer behaviour models in the traditional business‐to‐business and retail contexts. The findings of this study provide several important implications for research and practice. This paper concludes by discussing the contributions of this study and the limitations that could be addressed in future studies.
