Abstract

A small group of fault tolerance practitioners met in June, 1991, to attempt to identify how fault tolerance is being applied today, why fault tolerance is underused, and what can be done to bring fault tolerant practices into wider use. In this paper, a public forum is provided for other practitioners with diverse backgrounds to respond to the main conclusion of that workshop: that the state of the practice is the state of the art, i.e., that the practice is more art than engineering. Practitioners use a variety of fault tolerance techniques without the assurance that the contribution made by these techniques to dependability or safety is worth the investment. The conclusions of the workshop are addressed by representatives of Hitachi Ltd., Martin Marietta Corp., ASEA Brown Boveri Research Center, Sequoia Systems Inc., and the Honeywell Commercial Flight Systems Group.<>
