A broken wrist, for example, really hurts! But what do you do when you have a problem at work?
Uses[ edit ] RCA is applied to methodically identify and correct the root causes of events, rather than to simply address the symptomatic result.
Focusing correction on root causes has the goal of entirely preventing problem recurrence. RCA is typically used as a reactive method of identifying event s causes, revealing problems and solving them. Analysis is done after an event has occurred.
Insights in RCA make it potentially useful Problem solving analysis a preemptive method. In that event, RCA can be used to forecast or predict probable events even before they occur. While one follows the other, RCA is a completely separate process to incident management.
Examples[ edit ] For example, imagine a fictional segment of students who received poor testing scores. After initial investigation, it was verified that students taking tests in the final period of the school day got lower scores.
Further investigation revealed that late in the day, the students lacked ability to focus. Even further investigation revealed that the reason for the lack of focus was hunger. So, the root cause of the poor testing scores was hunger, remedied by moving the testing time to soon after lunch.
As another example, imagine an investigation into a machine that stopped because it overloaded and the fuse blew.
The investigation proceeds further and finds that the automatic lubrication mechanism had a pump which was not pumping sufficiently, hence the lack of lubrication.
Investigation of the pump shows that it has a worn shaft. This enabled scrap to get into the pump, and damage it. The root cause of the problem is therefore that metal scrap can contaminate the lubrication system.
Fixing this problem ought to prevent the whole sequence of events recurring. Compare this with an investigation that does not find the root cause: But there is a risk that the problem will simply recur, until the root cause is dealt with.
Note that "root causes" are likely to have many levels, and the analysis terminates at a level that is "root" only to the eyes of the current investigator. Thus, while the "root cause" shown above may have prevented the quoted recurrence, it would not have prevented other - perhaps more severe - future failures.
Classification[ edit ] Rather than one sharply defined methodology, RCA comprises many different tools, processes, and philosophies. However, several very-broadly defined approaches or "schools" can be identified by their basic approach or field of origin: Safety-based RCA arose from the fields of accident analysis and occupational safety and health.
Production-based RCA has roots in the field of quality control for industrial manufacturing. Failure-based RCA originates in the practice of failure analysis as employed in engineering and maintenance.
Systems-based RCA has emerged as an amalgam of the preceding schools, incorporating elements from other fields such as change managementrisk management and systems analysis.Problem Solving and Data Analysis questions might ask you to create an appropriate equation from a word problem, convert units, or understand the meaning of different numbers or variables in an equation.
Problem solving consists of using generic or ad hoc methods in an orderly manner to find solutions to problems. Some of the problem-solving techniques developed and used in artificial intelligence, computer science, engineering, mathematics.
