A Theory of Tailorable Technology Design

Tailorable technologies are a class of information systems designed with the intention that users modify and redesign the technology in the context of use. Tailorable technologies support user goals, intentions, metaphor, and use patterns in the selection and integration of technology functions in the creation of new and unique information systems. We propose a theory of tailorable technology design and identify principles necessary for the initial design. Following a Kantian style of inquiry, we identified four definitional characteristics of tailorable technology: a dual design perspective, user engagement, recognizable environments, and component architectures. From these characteristics, we propose nine design principles that will support the phenomenon of tailoring. Through a year-long case study, we refined and evidenced the principles, finding found that designers of tailorable technologies build environments in which users can both interact and engage with the technology, supporting the proposed design principles. The findings highlight a distinction between a reflective environment, where users recognize and imagine uses for the technology, and an active environment in which users tailor the technology in accordance with the imagined uses. This research contributes to the clarification of the role of theory in design science, expands the concept of possibilities for action to IS design, and proposes a design theory of a class of information systems for testing and refinement

The simplification of complex interactions for more inclusive social communication technologies (position paper)

New technologies, especially smart homes and mobile and ubiquitous technologies have the potential to foster improved quality of life in the older population. Some anticipated benefits are linked to specific applications in areas such as home automation, communication, shopping and health. However, some valuable potential benefits lie in building and sustaining relationships with remote extended family, particularly children and grandchildren, as well as with carers, neighbours and friends. Communication with geographically remote family can play an important role in helping to sustain autonomy, inclusion and independence. Reduction in isolation and improved participation have the potential to improve or sustain quality of life, but in addition they can lead to a reduction in vulnerability and sustained physical health. Another benefit can be to reassure adult children about the viability of their parent's independent living. Broadband "always-on" communications are potentially particularly useful tools in sustaining geographically remote relationships with extended family, as they can support many useful kinds of interaction, using modalities such as voice, video, pervasive annotation, selection, and remote concierging. Unfortunately, many possible new interactions are currently complex to manage, ruling them out on grounds of poor acceptability, accessibility and usability. However, our hypothesis is that a new interaction framework that combines social and technical components could be used to simplify many interactions of the kinds noted above sufficiently to the point where they would be rendered acceptable, accessible and usable. This paper outlines plans to test such a framework

User Participation and Tailorability in PSN Systems Design

User participation has received significant research attention in the past. Researchers have attempted to understand and demonstrate a link between user participation and system success, but studies have shown the link to be conditional. The purpose of this paper is to propose a type of system design when user participation is not required because the design consists of tailorable functionality, permits exploration through reversibility, and builds trust. In this paper past participation research is examined – including findings casting doubt on the participation-success link. Technology features are then offered to address unresolved user concerns identified in prior research. Future research of a non-participatory design in a Public Safety Network is also described. This paper contributes to IS design knowledge by expanding on the contingency view of user participation and system success. This paper also assists public safety professionals by offering potential design solutions to address user concerns

Developing living information systems through systems tailorability: Deferred systems design

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.An interpretivist investigation of computer-based business information systems was conducted in two commercial companies and two higher education institutes, by using both quantitative questionnaire survey and qualitative interview research methods. The investigation focused on the social and organisational context of information systems development and usage in these organisations. The utility of structured methodologies is now being questioned by some researchers who are calling for alternative approaches, and this investigation draws on that alternative strand of thinking. The collected data primarily reveals that the development and usage of information systems happens in changing organisations, which suggests that the design and usage of information systems must cater for such a changing or dynamic environment. Therefore the data is interpreted using a philosophical outlook encompassing the notion of "living" information systems and Critical Theory, and this philosophical stance regards information technology as liberating human endeavour in organisations. Five sub-concepts and the concept of deferred system's design are derived from the data, which have been formulated to account and cater for change in information systems environments. The concept of deferred system's design encourages the design of information systems which allow for organisational human behaviour, consisting of organisational change, uncertainty, and learning, to be mediated by information technology. A systems design principle called `deferred system's design decisions' is derived to enable designs of tailorable information systems, which may be regarded as one form of living information systems to facilitate such organisational behaviour. An intersubjective theoretical model called the spiral of change model of tailorable information systems is proposed to explain and understand better the changing organisational environment in which information systems must be developed and in which they must function. To inform practice a computer tool is proposed which enables conceptions of " tailorable information systems that employ the principle of deferred system's design decisions and enables modelling changing or dynamic information systems

Fostering Continuous User Participation by Embedding a Communication Support Tool in User Interfaces

This paper critically reviews previous IS literature on user participation and argues that the literature is mainly empirically or normatively oriented and lacks design research on developing system prototypes in order to foster continuous user participation. It then contributes to the current research by introducing a system prototype, a communication tool that enables users to participate while using their application systems in their work contexts. The prototype provides different communication channels for supporting user-designer communications and knowledge sharing among users with respect to application usage. When integrated in the interface of an application system, the tool can help to adapt and redesign the application. The initial evaluation of the communication tool within the context of an application system indicates its usefulness and usability

A Metadesign Theory for Tailorable Decision Support

Despite years of decision support systems (DSS) research, DSS artifacts are frequently criticized for lacking practitioner relevance and for neglecting configurability and contextual dynamism. Tailoring in end-user contexts can produce relevant emergent DSS artifacts, but design theory for this is lacking. Design science research (DSR) has important implications for improving DSS uptake, but generally this has not been promoted in the form of metadesigns with design principles applicable to other DSS developments. This paper describes a metadesign theory for tailorable DSS, generated through action design research studies in different primary industries. Design knowledge from a DSS developed in an agricultural domain was distilled and generalized into a design theory comprising: (1) a general solution concept (metadesign), and (2) five hypothesized design principles. These were then instantiated via a second development in which the metadesign and design principles were applied in a different domain (forestry) to produce a successful DSS, thus testing the metadesign and validating the design principles. In addition to contributing to DSR and illustrating innovation in tailorable technology, the paper demonstrates the utility of action design research to support theory development in DSS design

Secondary Design: A Case of Behavioral Design Science Research

As user interactions have become more central to specific classes of information systems, design theorizing must expand to support the processes of interaction and the evolution of information systems. This theorizing goes beyond user-aided, participatory design to consider users as designers in their own right during the ongoing creation and recreation of information systems. Recent theorizing about an emerging class of tailorable systems proposes that such systems undergo an initial, primary design process where features are built in prior to general release. Following implementation, people engage in a secondary design process where functions and content emerge during interaction, modification, and embodiment of the system in use. This case study reveals that people are engaged designers, framed by dualities in behaviors including planned and emergent behaviors, and participatory and reifying behaviors. We contribute to design science research by extending work on tailorable systems, investigating processes of secondary design in a highly interactive system suited to support user engagement. We also contribute more broadly to design science research by explicitly extending behavioral aspects associated with the use of information system artifacts
