As industrial systems become increasingly more complex, the maintenance and operating information increases both in volume and complexity. With the current pressures on manufacturing , the management of information resources has become a critical issue. In particular, ensuring that personnel can access current information quickly and e ectively when undertaking a speci®c task. This paper discusses some of the issues involved in, and the bene®ts of using, open hypermedia to manage and deliver a diverse range of information. While the paper concentrates on the problems speci®cally associated with manufacturin g organizations , the problems are generic across other business sectors, such as healthcare, defence and ®nance. The open hypermedia approach to information management and delivery allows a multimedia resource base to be used for a range of applications and it permits a user to have controlled access to the required information in an easily accessible and structured manner. Recent advancement in hypermedia also permits just-in-time support in the most appropriate format for all users. Our approach is illustrated by the discussion of a case study in which an open hypermedia system delivers maintenance and process information to factory-¯oor users to support the maintenance and operation of a very large manufacturin g cell.
