Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. Reliability is defined as the probability that a product, system, or service will perform its intended function adequately for a specified period of time, OR will operate in a defined environment without failure.

Nonunion is permanent failure of healing following a broken bone unless intervention (such as surgery) is performed. A fracture with nonunion generally forms a structural resemblance to a fibrous joint, and is therefore often called a "false joint" or pseudoarthrosis (from Greek pseudo-, meaning false, and arthrosis, meaning joint).
A home in Gilchrist, Texas, designed to resist flood waters survived Hurricane Ike in 2008.. In the fields of engineering and construction, resilience is the ability to absorb or avoid damage without suffering complete failure and is an objective of design, maintenance and restoration for buildings and infrastructure, as well as communities.
An outcome failure is a failure to obtain a good or service at all; a process failure is a failure to receive the good or service in an appropriate or preferable way. [6] Thus, a person who is only interested in the final outcome of an activity would consider it to be an outcome failure if the core issue has not been resolved or a core need is ...
Collapsed barn at Hörsne, Gotland, Sweden Building collapse due to snow weight. Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs.
For example, in an automobile, the failure of the FM radio does not prevent the primary operation of the vehicle. It is recommended to use Mean time to failure (MTTF) instead of MTBF in cases where a system is replaced after a failure ("non-repairable system"), since MTBF denotes time between failures in a system which can be repaired. [1]
The concept of a single point of failure has also been applied to fields outside of engineering, computers, and networking, such as corporate supply chain management [6] and transportation management. [7] Design structures that create single points of failure include bottlenecks and series circuits (in contrast to parallel circuits).
A structure without redundancy is called fracture-critical, meaning that a single broken component can cause the collapse of the entire structure. Bridges that failed due to lack of redundancy include the Silver Bridge and the Interstate 5 bridge over the Skagit River .
