This document discusses defence logistics information systems (DLIS) and the drivers for investment in them. Evolving trends in defence, like cost reduction pressures and the need for operational efficiency, are pushing more integration of industry into the defence environment. This requires advanced information systems for near real-time visibility. While some countries are making progress, DLIS remains fragmented globally. The document estimates $75 billion will be spent on DLIS by the US from 2011-2020 to replace aging systems and enable new capabilities. Challenges include overcoming legacy system dependency and user resistance to change.
