My own general opinion regarding automation is that its effectiveness is largely determined by (1) its creator's ability to accurately anticipate exceptional circumstances, and (2) by its creators ability to correctly implement the appropriate responses to those circumstances. Automated systems are doubtless superior in many ways, particularly for routine tasks, but the presence of an unexpected element can throw them for a loop. Ask any programmer (or any reader of comp.risks <grin>). : In the meantime, maybe this or this type of failure will occur : more often on this type than on that type. Who cares ? Isolation of common circumstances a/o tendencies in similar systems is a fairly standard debugging technique. Statistics are useful for finding tendencies, and tendencies can point to latent problems in a design. I would think a number of people have a legitimate interest in that kind of information, including the designers of said systems. -- -Rich Steiner >>>---> Programmer - IS/Flight Ops - Northwest Airlines Preferred e-mail address: firstname.lastname@example.org The Theorem Theorem: If If, Then Then Disclaimer: Any opinions expressed are mine, *not* my employer's!
