Root cause analysis (RCA)

Edition date: 2015-02-13
In Force
Available languages: Spanish, English, French
Summary: IEC 62740:2015 describes the basic principles of root cause analysis (RCA) and specifies the steps that a process for RCA should include. This standard identifies a number of attributes for RCA techniques which assist with the selection of an appropriate technique. It describes each RCA technique and its relative strengths and weaknesses. RCA is used to analyse the root causes of focus events with both positive and negative outcomes, but it is most commonly used for the analysis of failures and incidents. Causes for such events can be varied in nature, including design processes and techniques, organizational characteristics, human aspects and external events. RCA can be used for investigating the causes of non-conformances in quality (and other) management systems as well as for failure analysis, for example in maintenance or equipment testing. RCA is used to analyse focus events that have occurred, therefore this standard only covers a posteriori analyses. It is recognized that some of the RCA techniques with adaptation can be used proactively in the design and development of items and for causal analysis during risk assessment; however, this standard focuses on the analysis of events which have occurred. The intent of this standard is to describe a process for performing RCA and to explain the techniques for identifying root causes. These techniques are not designed to assign responsibility or liability, which is outside the scope of this standard. Keywords: root cause analysis (RCA), RCA techniques

L'IEC 62740:2015 décrit les principes basiques de l'analyse de cause initiale (RCA) et spécifie les étapes qu'il convient qu'un processus de RCA inclue. La présente norme identifie plusieurs attributs de techniques de RCA, qui aident à sélectionner la technique appropriée. Elle décrit chaque technique de RCA, ainsi que ses points forts et limites. La RCA est utilisée pour analyser les causes initiales des événements d'accent, que leurs conséquences soient positives ou négatives, mais est plus couramment utilisée pour l'analyse des défaillances et des accidents. Les causes de tels événements peuvent être de nature multiple, notamment en fonction de la conception, des processus et des techniques, des caractéristiques organisationnelles, des aspects humains et des événements externes. La RCA peut être utilisée pour étudier les causes de non-conformité en termes de qualité (ou autres) des systèmes de gestion ainsi que pour l'analyse des défaillances, par exemple lors de la maintenance ou de l'essai des équipements. La RCA est utilisée pour analyser des événements d'accent qui se sont produits, cette norme ne couvre donc que les analyses a posteriori. Il est reconnu que certaines des techniques de RCA avec adaptations peuvent être utilisées de manière proactive lors de la conception et du développement d'entités et pour l'analyse causale au cours de l'évaluation des risques; cependant, la présente norme met l'accent sur l'analyse des événements qui se sont produits. L'objectif de la présente norme est de décrire un processus en vue de réaliser une RCA et d'expliquer les techniques permettant d'identifier les causes initiales. Lesdites techniques n'ont pas été conçues pour identifier la responsabilité ou la fiabilité, car ceci ne fait pas partie du domaine d'application de la présente norme. Mots clés: analyse de cause initiale (RCA), de techniques de RCA
