Abstract
Even when we prepare countermeasures against expected project troubles, we cannot apply each counter-measure as its original form. In order to coop with project troubles, we should recognize trouble structures and create some sort of awareness to the troubles. In this paper, the authors propose a trouble detection and management methodology based on standardization of project process in a form of IDEF0. In this methodology, it is assumed that a little difference between the said standardized IDEF0 and the actual activity becomes a source of trouble. Illustrative example of the proposed methodology is also presented by using Project Trouble Casebook collected by Engineering Advancement Association of Japan.
