A Critical System (Safety or Life) is a system whose failure or malfunction may result in one (or more) of the following outcomes:
Critical related systems comprise of everything (hardware, software, infrastructure, and the human aspects) needed and related to perform one or more functions, in which failure would cause a significant increase in risk for people, property, products and/or services involved. Critical systems are those that do not have full responsibility for controlling hazards and/or environments such as loss of life, severe injury or severe environmental damage. The severity, occurrence, and detection of a failure becomes hazardous in conjunction with the failure of other systems or human error.
Risks of these sort are usually managed with the methods and tools of design, engineering, process and quality management. A critical system is designed to loose less than one life per billion hours of operation (one occurrence every 500,000 years). Typical process design methods include Failure Mode Effect Analysis (FMEA) and Fault Tree Analysis (FTA). Global Planning Group’s mandate is to help you … Anticipate The Future …
Because most of the time you may pick two of the following three … but not more:
Failure Mode Effect Analysis (FMEA) and Failure Modes Effect and Critical Analysis (FMECA) are methodologies designed to identify potential failure modes for a product or process … to assess the risk associated with those failure modes … to rank the issues in terms of importance … and to identify and carry out corrective actions to address the most serious concerns.
