Conclusion: When making the decision to invest in wireless, managers are presented with economic arguments from suppliers. Examining the variety of case studies* reveals that not all the arguments are valid, and this fact should not be significant, because not all decisions, should be, or are based on economic grounds.
Indeed, the case for a wireless solution in enterprises may be impelled by the same tacit logic of fashion. In other words, as more companies adopt it, perhaps even for purely financial and logical reasons, the spread of the technology becomes more compelling. If that line of argument appears fanciful, it is the same reason why the DVD is so popular, and in fact, one of the background causes as to how the PC took hold in companies, twenty years ago.
To assess whether to join the wireless movement or not, managers can simply do two things.
Survey similar sized companies and organisations that have adopted it.
Discount the putative efficiency benefit from any calculation of ROI in a short-term period, say the first year.
Widespread adoption of technology arises from network effects; in essence, because your competitors are doing it, there is a justifiable reason to do likewise.
