Traceability is the capability to trace something.[1] In some cases, it is interpreted as the ability to verify the history, location, or application of an item by means of documented recorded identification.[2]
Other common definitions include the capability (and implementation) of keeping track of a given set or type of information to a given degree, or the ability to chronologically interrelate uniquely identifiable entities in a way that is verifiable.
Traceability is applicable to measurement, supply chain, software development, healthcare and security.
