By gathering data about errors made, then collating, grouping and analyzing them, it can be determined whether a disproportionate amount of similar errors are being made. If this is the case, a contributing factor may be disharmony between the respective systems/routines and human nature or propensities. The routines or systems can then be ...
Emmental cheese with eyes. When cut into slices, each slice will have holes of varying sizes and positions. In the Swiss cheese model, an organization's defenses against failure are modeled as a series of imperfect barriers, represented as slices of cheese, specifically Swiss cheese with holes known as "eyes", such as Emmental cheese.
Other latent variables correspond to abstract concepts, like categories, behavioral or mental states, or data structures. The terms hypothetical variables or hypothetical constructs may be used in these situations. The use of latent variables can serve to reduce the dimensionality of data. Many observable variables can be aggregated in a model ...
The impact of any latent fault tests, and The operational profile (environmental stress factors). Given a component database calibrated with field failure data that is reasonably accurate, [ 1 ] the method can predict device level failure rate per failure mode, useful life, automatic diagnostic effectiveness, and latent fault test effectiveness ...
graph with an example of steps in a failure mode and effects analysis. 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.
He suggests compensating for this when building usable systems, thus allowing a higher percentage of users to complete tasks without errors: For example, suppose the goal of your program is to allow people to convert digital camera photos into a web photo album.
In construction contracting, a latent defect is defined as a defect which exists at the time of acceptance but cannot be discovered by a reasonable inspection. [2]In the 1864 US case of Dermott v Jones, the latent defect lay in the soil on which a property had been built, giving rise to problems which subsequently made the house "uninhabitable and dangerous".
