Latent Failure Model

I've tried searching for an article on this concept by the few names I know it by: Latent Failure Model, Complete System Failure Model, and Swiss Cheese Effect. It is an important concept in accident/mishap and safety investigation. The basic concept is that while on the surface it may seem that one individual is the cause of an accident, one can often find failures within the various levels of the system that were to blame, as a group. The various system levels are, from top to bottom: Institution, Organization, Profession, Team, Individual, and Technical. Failures at each level cause an unchecked chain of events leading to an accident or mishap that could have been prevented at several different checkpoints, had those failures not occurred.

Explanation of the Latent Failure Model, incl. graphics

Feedback systems

An article about feedback systems would be nice to have: a market economy is a feedback system - that's, if you think about it, the reason behind it's success: it allows one to put each part to its correct best place in the system. Also the natural evolution's competition is statistically a faadback system. Objective thinking with a holistic view, honesty and justice mean giving each thing feedback according to what it is like. So they too should be valued if one values the market economy's success. An article about this subject would bring the world toward good.

You might want to take a look at feedback, and also post this suggestion at Talk:feedback. -- John Broughton | ^(??) 16:47, 20 January 2007 (UTC)[reply]
