Paper presented at The 13th International Florida Artificial Intelligence Research Society Conference, FLAIRS 1999, Menlo Park, FL: pp. 170-174.Exploiting lessons learned is a key knowledge management
(KM) task. Currently, most lessons learned systems are
passive, stand-alone systems. In contrast, practical KM
solutions should be active, interjecting relevant information
during decision-making. We introduce an architecture for
active lessons delivery systems, an instantiation of it that
serves as a monitor, and illustrate it in the context of the
conversational case-based plan authoring system HICAP
(Muñoz-Avila et al., 1999). When users interact with
HICAP, updating its domain objects, this monitor accesses a
repository of lessons learned and alerts the user to the
ramifications of the most relevant past experiences. We
demonstrate this in the context of planning noncombatant
evacuation operations
