This invention is a method and system for troubleshooting a breakdown or malfunction in an industrial plant facility identified by alarm or shutdown signals based upon forming a knowledge base of knowledge elements for providing advice and guidance to the technician. Each fault condition has a set of knowledge elements arranged in a sequence having an ordered hierarchy corresponding to different levels of information. The subordinate knowledge elements are linked to permit selection for display on a computer monitor in a specified manner and in a predetermined cascade arrangement relative to each higher level knowledge element to which it is linked.
