The author describes the work done under his leadership in the IMPACT Programme (a business research organisation within KPMG) into information management. He argues that there can be no corporate knowledge without good corporate information management. Most organisations today, although they recognise that information is important and despite being 40 years into the information age, do not manage their information properly. The IMPACT Programme has developed an Agenda for Directors and Managers to use in addressing good information management—the essence of which is to treat information as an asset and manage it like everything else. This has been followed by the first management tool to measure status and progress—the Information Health Index or IHI, the first results from which are just being obtained. The article describes what practical steps can be taken by businesses today to start implementing good information management and how IMPACT is addressing a series of related issues which together will provide the keys to open the gateway to knowledge.
