The constant pressure to achieve increased efficiency and profitability improvements drives companies to look at new technologies for ways to develop sustainable advantages. At the same time, the breathtakingly rapid technological development of these technologies leads, not surprisingly, to different misconceptions about the impact of IT on businesses.  This dissertation aims at clarifying some of these misconceptions by exploring one such technological breakthrough, namely wireless information systems, as used to support mobile workforces. The dissertation analyses three companies devoted to the implementation of wireless information systems, that were confronted with a number of challenges, and investigates how these challenges were met by means of different capability development activities. Evidence from the cases shows that what really matters is not the technology in itself, but how organizations use it. This study suggests that the firms that give the best performance are not necessarily those that implement different breeds of technology, but rather those that are able to learn from the challenges they are confronted with – doing so moreover on repeated occasions by means of interlinked organizational innovation processes. Thus, a piece of advice offered in this dissertation is that it is not always so important to possess all the right capabilities from the beginning, but that one needs to possess the right capabilities to develop new capabilities. / <p>Diss.
