Advances in computer technology typically find their way into education after a short generation of success in other settings. This is an elaboration of one such technology—knowledge management systems (KMS)—and its application to instructional design. An examination of the development of KMS from information systems. computer-supported collaborative work environments and object-oriented systems, leads to a discussion of reusability. The focus is on the use of KMS by instructional designers. A conceptual framework for distributed instructional design is provided along with examples of support tools. These tools and the associated design framework are in use, and anecdotal evidence of effects and impact is provided. As such tools become more widely used to support the planning, implementation and management of instructional systems and learning environments, it is reasonable to expect the nature of instructional design practice to change.
