Interactive Innovation of Technology for Mobile Work

1,222 views

Published on

Despite the increasing popularity of mobile information systems, the actual processes leading to the innovation of mobile technologies remain largely unexplored. This study uses Action Research to examine the innovation of a mobile RFID technology. Working from Activity Theory, it departs from the prevalent product-oriented view of innovation and treats technology-in-the- making as a complex activity, made possible through the interaction of manufacturers, their organisational clients and their respective mobile workers. The lens of a normative Interactive Innovation Framework reveals distinctive interaction problems that bear on the innovation activity. In addition to difficulties emerging from dissimilar motivations for the innovation project, the mobile setting presents unique contradictions based on the geographical distribution of its participants, the diverse role of mobile technology, the complexity of interacting through representations and the importance of the discretion with which mobile work activities are carried out today.

European Journal of Information Systems (2008) 17, 305–320. doi:10.1057/ejis.2008.18 Keywords: interactive innovation; mobility; technology for mobile work; mobile technology; action research; activity theory Introduction The past decades have unveiled an impressive trajectory of mobile technology, marked primarily by the advancements from early mobile telephones, available to the elite few, to the highly advanced and diffused mobile devices of today. Intrigued by new technological affordances (Gibson, 1977), Information Systems (IS) scholars increasingly turn their attention to the impact of mobile devices on individuals and organisa- tions. In the meanwhile, manufacturers, concerned with staying compe- titive in an industry actively rivalling for corporate accounts, are starting to invite their future users to participate in the process of innovation. These evolving cooperative innovation projects between manufacturers and users are highly complex and benefit from an innovation approach that clearly defines the roles and responsibilities of each participant. Some lessons can be learned from fairly recent co-constructive developments; however, these lessons are largely based on single organisational contexts, non-mobile computing devices and a dialogue between innovators and users in fixed-location settings. But since mobile settings and technologies that span time and location fundamentally challenge the interaction habits subsumed by non-mobile contexts, manufacturers and innovatorsReceived: 7 August 2007Revised: 4 December 2007 support a fresh approach for interactive innovation within mobile2nd Revision: 12 June 2008 environments.3rd Revision: 24 June 2008 Commissioned by a leading mobile device manufacturer, our researchAccepted: 25 June 2008 focused on first developing a conceptual framework for interactive
