Consequently, the phrase "high reliability" has come to mean that high risk and high effectiveness can co-exist, for organizations that must perform well under trying conditions, and that it takes intensive effort to do so. While the early research focused on high risk industries, other expressed interest in HROs and sought to emulate their ...
The term high reliability organization (HRO) is an emergent property described by Weick (and Karlene Roberts at UC-Berkeley). Highly mindful organizations characteristically exhibit: a) Preoccupation with failure, b) Reluctance to simplify c) Sensitivity to operations, d) Commitment to Resilience, and e) Deference to Expertise.
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.

Healthcare systems are complex in that they are diverse in both structure (e.g. nursing units, pharmacies, emergency departments, operating rooms) and professional mix (e.g. nurses, physicians, pharmacists, administrators, therapists) and made up of multiple interconnected elements with adaptive tendencies in that they have the capacity to change and learn from experience.
A product is said to follow the bathtub curve if in the early life of a product, the failure rate decreases as defective products are identified and discarded, and early sources of potential failure such as manufacturing defects or damage during transit are detected. In the mid-life of a product the failure rate is constant.
For example, while there are many reliable tests of specific abilities, not all of them would be valid for predicting, say, job performance. While reliability does not imply validity, reliability does place a limit on the overall validity of a test. A test that is not perfectly reliable cannot be perfectly valid, either as a means of measuring ...
Human error, human performance, and human reliability are especially important to consider when work is performed in a complex and high-risk environment. [ 2 ] Strategies for dealing with performance-shaping factors such as psychological stress , cognitive load , fatigue include heuristics and biases such as confirmation bias , availability ...
Reliability-centered maintenance (RCM) is a concept of maintenance planning to ensure that systems continue to do what their users require in their present operating context. [1] Successful implementation of RCM will lead to increase in cost effectiveness, reliability, machine uptime, and a greater understanding of the level of risk that the ...
