Root Cause Analysis (RCA) Task
A Root Cause Analysis (RCA) Task is a problem solving task (for some problem statement) that requires the identifying of root causes.
- Context:
- It can produce a Root Cause Analysis Report.
- It can be a part of a Continuous Improvement Process.
- It can include:
- Identify and describe the problem clearly.
- Establish a timeline from the normal situation until the problem occurs.
- Distinguish between the root cause and other causal factors (e.g., using event correlation).
- Establish a causal graph between the root cause and the problem.
- …
- Example(s):
- an IT System RCA Task.
- a 5 Whys Task.
- …
- Counter-Example(s):
- See: Systems Analysis, Kepner-Tregoe Analysis, Human Factors Analysis, Continuous Improvement, Incident Management, Accident Analysis, Five Whys.

- In science and engineering, root cause analysis (RCA) is a method of problem solving used for identifying the root causes of faults or problems. [1] It is widely used in IT operations, manufacturing, telecommunications, industrial process control, accident analysis (e.g., in aviation, [2] rail transport, or nuclear plants), medicine (for medical diagnosis), healthcare industry (e.g., for epidemiology), etc. Root cause analysis is a form of deductive inference since it requires an understanding of the underlying causal mechanisms of the potential root causes and the problem.
RCA can be decomposed into four steps:
- Identify and describe the problem clearly.
- Establish a timeline from the normal situation until the problem occurs.
- Distinguish between the root cause and other causal factors (e.g., using event correlation).
- Establish a causal graph between the root cause and the problem.
- RCA generally serves as input to a remediation process whereby corrective actions are taken to prevent the problem from reoccurring. The name of this process varies from one application domain to another. According to ISO/IEC 31010, RCA may include the techniques Five whys, Failure mode and effects analysis (FMEA), Fault tree analysis, Ishikawa diagram and Pareto analysis.

- QUOTE: ... Root Cause Analysis (RCA) is a method that identifies and isolates the root cause of problems. Root causes are those factors that can be eliminated to prevent an adverse event from happening.
Root Cause Analysis (RCA) assumes that it’s more efficient to prevent and solve underlying problems than treating symptoms or putting out fires. A variety of techniques and principles can be used to determine the root cause of an event or trend. Root Cause Analysis (RCA) can identify the root causes of an event or trend, and not just cause and effectIt's the change in the average value of the output caused by....
Root cause analysis (RCA) is crucial to problem-solving. Preventing an event from happening is better than reacting to its harmful consequences. RCA is a permanent solution that eliminates the cause of the defectA defect is a physical, functional, or aesthetic attrib....

- Root cause analysis (RCA) is a method of problem solving used for identifying the root causes of faults or problems. A factor is considered a root cause if removal thereof from the problem-fault-sequence prevents the final undesirable event from recurring; whereas a causal factor is one that affects an event's outcome, but is not a root cause. ...
