RCCA PROBLEM SOLVING

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. October Learn how and when to remove this template message. Retrieved from ” https: Looking again at the example above in industrial process control, a deeper investigation could reveal that the maintenance procedures at the plant included periodic inspection of the lubrication subsystem every two years, while the current lubrication subsystem vendor’s product specified a 6-month period. Control plan Statistical process control 5S Poka-yoke. See Wikipedia’s guide to writing better articles for suggestions. Fixing this problem ought to prevent the whole sequence of events recurring.

Effective problem statements and event descriptions as failures, for example are helpful and usually required to ensure the execution of appropriate root cause analyses. Another example is the computer security incident management process , where root-cause analysis is often used to investigate security breaches. RCA is also used in conjunction with business activity monitoring and complex event processing to analyze faults in business processes. Imagine an investigation into a machine that stopped because it overloaded and the fuse blew. One can use 5 Whys and cause and effect diagrams to map causes against the effect or problem identified.

A team effort is typically required.

Root cause analysis

Compare this with an investigation that does not find the root cause: The team needs to be formally thanked by the organization. Learn how and when to remove these template messages. To be effective, root cause analysis must be performed systematically. The name rxca this process varies from one application domain to another.

The 8D problem solving model establishes a permanent corrective action based on statistical analysis of the problem and focuses on the origin of the probkem by determining its root causes. RCA is also used in change managementrisk managementand systems analysis.

Business process mapping Process capability Pareto chart. Although it originally comprised eight stages, or disciplines, the eight disciplines system was later augmented by an initial planning stage. For example, in the ITIL service management framework, the goal of incident management is to resume a faulty IT service as soon as possible reactive managementwhereas problem management deals with solving recurring problems for good by addressing their root causes proactive management.

Investigation of why the shaft was worn discovers that there isn’t an adequate mechanism to prevent metal scrap getting into the pump. The example above illustrates how RCA can be used in manufacturing.

Another example is the computer security incident management processwhere root-cause analysis is often used to investigate security breaches.

The real root cause could be so,ving design issue if there is no filter to prevent the metal scrap getting into the system. Although removing a causal factor can benefit an outcome, it does not problrm its recurrence with certainty. Views Read Edit View history.

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

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. Without delving in the idiosyncrasies of specific problems, several general conditions can make RCA more priblem than it may appear at first sight.

Plan – Plan for solving the problem soolving determine the prerequisites. Finding a few relevant events in such a mass of irrelevant events is akin to finding the proverbial needle in a haystack.

Unsourced material may be challenged and removed. Root cause analysis Failure mode and effects analysis Multi-vari chart.

Another consists in comparing the situation under investigation with past situations stored in case libraries, using case-based reasoning tools. One way to trace down root causes consists in using hierarchical clustering and data-mining solutions such as graph-theory-based data mining.
