This study examines business use cases for Internet-of-Things (IoT) applications by eight companies across several industries. The focus is: Why should business executives care about IoT? As illustrated by these companies, there is a spectrum of business motivations for implementing IoT applications, along with tradeoffs and challenges. By applying data warehousing with data analytics as the Analytics-of-Things (AoT), IoT applications can leverage business value with new business opportunities. The study concludes with recommendations to executives for properly assimilating IoT applications into their IT architecture and corporate culture.
