Traceability refers to the completeness of the information about every step in a process chain.
The term traceability is for example used to refer to an unbroken chain of measurements relating an instrument's measurements to a known standard. Traceability can be used to certify an instrument's accuracy relative to a known standard. In classical physics and engineering, measurement generally refers to the process of estimating or determining the ratio of a magnitude of a quantitative property or relation to a unit of the same type of quantitative property or relation. ...
An instrument is a concrete or abstract tool intended for a purpose other than mechanical work, in particular a refined one. ...
In science, engineering, industry and statistics, accuracy is the degree of conformity of a measured or calculated quantity to its actual, nominal, or some other reference, value. ...
(In the USA, national standards for weights and measures are maintained by the National Institute of Standards and Technology. As defined by NIST, "Traceability requires the establishment of an unbroken chain of comparisons to stated references.") The National Institute of Standards and Technology (or NIST) formerly known as The National Bureau of Standards is a non regulatory agency of the United States Department of Commerce’s Technology Administration. ...
In logistics, traceability refers to the capability for tracing goods along the distribution chain on a batch number or series number basis. Traceability is an important aspect for example in the automotive industry, where it makes recalls possible, or in the food industry where it contributes to food safety. Logistics is the art and science of managing and controlling the flow of goods, energy, information and other resources. ...
In logistics, tracing is the process of uniformly generating a sample of traces of objects that are forwarded to, processed for, applied in or disposed of usage. ...
A Batch is a group of similar items produced, processed or gathered together and treated as a single unit. ...
Foodborne illness or food poisoning is caused by consuming food contaminated with pathogenic bacteria, toxins, viruses, prions or parasites. ...
In software development, the term traceability refers to the ability to link the requirements set forth at the beginning of a project, to the corresponding design artefacts, to the resulting software and associated test cases. This allows for efficient change impact analysis. It is usually accomplished in the form of a matrix created for the Verification and Validation of the project. In transaction processing software, traceability implies use of a unique piece of data (e.g., order date/time or a serialized sequence number) which can be traced through the entire software flow of all relevant application programs. Messages and files at any point in the system can then be audited for correctness and completeness, using the traceability key to find the particular transaction. This is also sometimes referred to as the transaction footprint. Software engineering (SE) is the profession concerned with specifying, designing, developing and maintaining software applications by applying technologies and practices from computer science, project management, and other fields. ...
In software engineering, a test case is a set of conditions or variables under which a tester will determine if a requirement upon an application is partially or fully satisfied. ...
It is important to be able to tell if a software system meets specifications and if it runs correctly. ...
