The Internet of Things (IoT) has been given scant attention in e-government literature, whereas promises are high. The IoT describes a situation whereby physical objects are connected to the Internet and are able to communicate with, and identify themselves to, other devices. These devices generate a huge amount of data. When it is possible to combine data from devices and other systems, new insights may be created which may provide important benefits. In this paper we explore the expected benefits of IoT for e-governance by investigating case studies at the Directorate General of Public Works and Water Management of the Netherlands. The results show that IoT has a variety of expected political, strategic, tactical and operational benefits which implies that IoT enables effective knowledge management, sharing and collaboration between domains and divisions at all levels of the organisation, as well as between government and citizens.
