Engineering experience base maintenance knowledge

The value of a corporate information system such as an experience base tends to degrade with time. To keep the value of such a system, maintenance is an essential. Maintenance should not simply happen ad-hoc but systematically and based on specific maintenance knowledge. As a jump-start for maintenance, maintenance knowledge should be available right from the start of continuous operation. This paper describes how to systematically develop ("to engineer") such maintenance knowledge during buildup of the corporate information system.
