Single point of failure. In this diagram the router is a single point of failure for the communication network between computers. A single point of failure (SPOF) is a part of a system that, if it fails, will stop the entire system from working. [1] SPOFs are undesirable in any system with a goal of high availability or reliability, be it a ...
Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects. For each component, the failure modes and their resulting effects on the rest of the system ...
Failure modes, effects, and diagnostic analysis (FMEDA) is a systematic analysis technique to obtain subsystem / device level failure rates, failure modes and diagnostic capability. The FMEDA technique considers: The operational profile (environmental stress factors). Given a component database calibrated with field failure data that is ...
Event tree analysis (ETA) is a forward, top-down, logical modeling technique for both success and failure that explores responses through a single initiating event and lays a path for assessing probabilities of the outcomes and overall system analysis. [1] This analysis technique is used to analyze the effects of functioning or failed systems ...
The Goal is a management-oriented novel by Eliyahu M. Goldratt, a business consultant known for his theory of constraints, and Jeff Cox, the author of several management-oriented novels. [1] The Goal was originally published in 1984 and has since been revised and republished. [2] This describes a case study in operations management, focusing on ...
Fault tolerance is the ability of a system to maintain proper operation despite failures or faults in one or more of its components. This capability is essential for high-availability, mission-critical, or even life-critical systems. Fault tolerance specifically refers to a system's capability to handle faults without any degradation or downtime.
Lean startup. Lean startup is a methodology for developing businesses and products that aims to shorten product development cycles and rapidly discover if a proposed business model is viable; this is achieved by adopting a combination of business- hypothesis -driven experimentation, iterative product releases, and validated learning.
The bus factor is a measurement of the risk resulting from information and capabilities not being shared among team members, derived from the phrase "in case they get hit by a bus". It is also known as the bus problem, truck factor, [1] or bus/truck number. [citation needed] The concept is similar to the much older idea of key person risk, but ...
