Countless books and papers have been written about how to identify, classify, eliminate, prevent and compensate for it. This bias towards the study of performance failures, leads to a neglect of normal or 'error-free' performance and the assumption that as failures and successes have different origins there is little to be gained from studying them together. Erik Hollnagel believes this assumption is false and that safety cannot be attained only by eliminating risks and failures. The ETTO Principle looks at the common trait of people at work to adjust what they do to match the conditions - to what has happened, to what happens, and to what may happen. It proposes that this efficiency-thoroughness trade-off (ETTO) - usually sacrificing thoroughness for efficiency - is normal. While in some cases the adjustments may lead to adverse outcomes, these are due to the very same processes that produce successes, rather than to errors and malfunctions. The ETTO Principle removes the need for specialised theories and models of failure and 'human error' and offers a viable basis for effective and just approaches to both reactive and proactive safety management."--Provided by publisher. 606 $aPerformance technology 606 $aPerformance$xPsychological aspects 606 $aIndustrial accidents 615 0$aPerformance technology. 615 0$aPerformance$xPsychological aspects. 615 0$aIndustrial accidents. 676 $a658.3 676 $a658.3/14 676 $a658.314 700 $aHollnagel$b Erik$f1941-$0850318 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910971604803321 996 $aThe ETTO principle$94472544 997 $aUNINA
