But there is a risk that the problem will simply recur, until the root cause is dealt with. The apparant root cause of the problem is therefore that metal scrap can contaminate the lubrication system. The name of this process varies from one application domain to another. Finding a few relevant events in such a mass of irrelevant events is akin to finding the proverbial needle in a haystack. The example above illustrates how RCA can be used in manufacturing.

See Wikipedia’s guide to writing better articles for suggestions. Root cause analysis Failure mode and effects analysis Multi-vari chart. RCA is also used in change management , risk management , and systems analysis. To be effective, root cause analysis must be performed systematically. Please help improve it or discuss these issues on the talk page.

Retrieved from ” https: Speed is not as important here as the accuracy and precision of the diagnosis. For aircraft accident analyses, for example, the conclusions of the investigation and the root causes that are identified must be backed up by documented evidence. Compare this with an investigation that does not find the root cause: RCA is also used in conjunction with business activity monitoring and complex event rpoblem to analyze faults in business processes.
Without delving in the idiosyncrasies of specific problems, several general conditions can make RCA more difficult than it may appear at first sight.
Root cause analysis
Although removing a causal factor can benefit an outcome, it does not prevent its recurrence with certainty. Investigation of why the shaft was worn discovers that there isn’t an adequate mechanism to prevent metal scrap getting into the pump.
See Wikipedia’s guide to writing better ptoblem for suggestions. RCA is also routinely used in industrial process controle. A causal factorconversely, is one that affects an event’s outcome, but is not the root cause. Please help improve it or discuss these issues on the talk page.
Despite the different approaches among the various schools of root cause analysis and the specifics of each application domain, RCA generally follows the same four steps. This article’s tone or style may not reflect the encyclopedic tone used on Wikipedia.

A team effort is typically required. Looking again at the example above in industrial process control, a deeper investigation could reveal that the maintenance procedures at the soving included periodic inspection of the lubrication subsystem every two years, while the current lubrication subsystem vendor’s product specified a 6-month period.

Another consists in comparing the situation under investigation with past situations stored in case libraries, using solvong reasoning tools.
