Root cause analysis is the last and most complex step of event correlation. It consists of analyzing dependencies between events, based for instance on a model of the environment and dependency graphs, to detect whether some events can be explained by others.
In March 1997, the IRIS database was uploaded to the internet. In 2004, the IRIS process was changed to add an interagency review led by the Office of Management and Budget (OMB) and to place a higher emphasis on outside peer review of IRIS assessments. [citation needed] The IRIS program was once again revised in April 2008.
A FRACAS system may attempt to manage multiple failure reports and produces a history of failure and corrective actions. FRACAS records the problems related to a product or process and their associated root causes and failure analyses to assist in identifying and implementing corrective actions.
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), medical diagnosis, the healthcare industry (e.g., for epidemiology ...
It treats multiple problems in a system as symptoms arising from one or a few ultimate root causes or systemic core problems. It describes, in a visual (cause-and-effect network) diagram, the main perceived symptoms (along with secondary or hidden ones that lead up to the perceived symptoms) of a problem scenario and ultimately the apparent ...
Iridodialyses are usually caused by blunt trauma to the eye, [2] but may also be caused by penetrating eye injuries. [7] An iridodialysis may be an iatrogenic complication of any intraocular surgery [10] [11] [12] and at one time they were created intentionally as part of intracapsular cataract extraction. [13]

Sample Ishikawa diagram shows the causes contributing to problem. The defect, or the problem to be solved, [1] is shown as the fish's head, facing to the right, with the causes extending to the left as fishbones; the ribs branch off the backbone for major causes, with sub-branches for root-causes, to as many levels as required.
