Analytical methods to determine the core problem(s) of an organization, process, products, market, etc.
A process improvement and error or defect prevention tool that examines the individual processes within a system, identifies the control or decision points, and uses a series of why? questions to determine the reasons for variations in the process paths.
A Telcordia standard for Telecommunications Management Network (TMN) architectures. The objective of RCA is to reduce the amount of analysis time spent determining why multiple alarms occur. It is expected that network management of a large-scale data network may receive up to 700 alarm messages per second during peak operating periods. To handle this level of alarm traffic RCA automatically processes certain alarm messages in predetermined ways one of them being automatic generation of a trouble ticket for the root cause of a problem that generated multiple alarm messages.
Research of an incident that initiated an alert or alarm and report the findings to the customer contact as determined by the customer's escalation procedures.
A technique for uncovering the cause of a failure by deductive reasoning down to the physical and human root(s), and then using inductive reasoning to uncover the much broader latent or organizational root(s.)
Study of original reason for nonconformance with a process. When the root cause is removed or corrected, the nonconformance will be eliminated.
A method to find the basic reasons for failures in a process
A method of resolving a non-conformance, by tracing back from the end failure to its original (root) cause. The basic tool for understanding and eliminating the sources of productivity losses.
Using one or more various tools to determine the root cause of a specific failure.
The process of determining the underlying reasons an error, fault, failure, or bug occurred. The concern is not how to fix the problem but to discover why it occurred and prevent this type of problem from occurring in the future.
Process of consistently classifying calls by type and technology to discover the common causes for the calls.
Root cause analysis (RCA) is a class of problem solving methods aimed at identifying the root causes of problems or events. The practice of RCA is predicated on the belief that problems are best solved by attempting to correct or eliminate root causes, as opposed to merely addressing the immediately obvious symptoms. By directing corrective measures at root causes, it is hoped that the likelihood of problem recurrence will be minimized.
