Valuable Innovation: Organising innovation for more than material value (2009)

In this master thesis an extensive literature research over a longitudinal period of fourteen years reveals a focus on material value in terms of tangible, visible and easy to measure assets. This focus manifests itself in six prominent themes derived out of 95 selected papers published in MIS Quarterly, an established, well-acknowledged and influential journal in the field of information systems research. Publications were selected on relevance with regard to innovation due to the association of information systems with change and development. A broader concept of value is identified and constructed out of two concepts, immaterial value and immaterial values. Although they only differ by one letter in name, their theoretical underpinning and the implications for information systems research differs widely. By defining immaterial value as a measurable result of the interplay of human, structural and customer capital, insights in existing literature with a focus on output are augmented, quantified and decomposed. In contrast, the emphasis on social interaction, mutual understanding and the need for imagination by using metaphors, makes the concept of immaterial values applicable to themes with a focus on input variables and conditions. The broader concept of value is applied to contemporary theory and practice. The overall finding is that by applying a broader concept of value, the field of information systems research can be enriched. PDF

Blauwdruk van de succesvolle webinkel: betere prestaties door consumentenbegrip en vertrouwen (2007)

Ieder jaar komen er enkele duizenden nieuwe webwinkels bij in Nederland (Kamer van Koophandel 2006). Veel webwinkels redden het niet. Uit onderzoek blijkt dat het aankoopproces van de consument niet altijd even goed wordt ondersteund. Het aankoopproces is drieledig (Zeng & Reinartz 2003): zoeken, evalueren en transactie. Volgens Lee (2002) speelt vertrouwen een belangrijke rol bij het aankoopgedrag van de consument. Beide onderzoeken belichten een belangrijk deel succescriteria voor webwinkels. Toch ontbreekt er op dit moment een geïntegreerd model wat gebruikt kan worden door webwinkels om prestatie te analyseren en te verbeteren. Het doel van dit onderzoek is het integreren van verschillende theorieën in een blauwdrukachtig model. Het onderzoek beslaat een uitgebreide literatuurstudie met als aanvulling een case analyse. Er wordt ingegaan op het begrip vertrouwen en wordt duidelijk hoe vertrouwen tot stand komt. De case analyse belicht processen van webwinkels vanachter de schermen. Op die manier wordt er optimaal inzicht verkregen om een model op te stellen. PDF
