Software Engineering: Traceability (Definitions)

"The evidence of an association between a requirement and its source requirement, its implementation, and its verification." (Sandy Shrum et al, "CMMI®: Guidelines for Process Integration and Product Improvement", 2003)

"A discernable association among two or more logical entities such as requirements, system elements, verifications, or tasks." (Sandy Shrum et al, "CMMI: Guidelines for Process Integration and Product Improvement" 2nd Ed., 2006)

"The quality of information to be linked to its background or sources." (Martin J Eppler, "Managing Information Quality" 2nd Ed., 2006)

[horizontal traceability:] "The tracing of requirements for a test level through the layers of test documentation (e.g., test plan, test design specification, test case specification, and test procedure specification or test script)." (Tilo Linz et al, "Software Testing Practice: Test Management", 2007)

[vertical traceability:] "The tracing of requirements through the layers of development documentation to components." (Tilo Linz et al, "Software Testing Practice: Test Management", 2007)

"Starting from requirements, traceability establishes a correlation between elements of different development steps." (Lars Dittmann et al, "Automotive SPICE in Practice", 2008)

"The degree to which each element of a product can be mapped back to the individual requirement or requirements, which in-turn, are linked back to the original validated market or customer need." (Steven Haines, "The Product Manager's Desk Reference", 2008)

"Capability of linking artifacts produced by enterprise architecture or realization activities to other artifacts from which they originate or to which they refer." (Gilbert Raymond & Philippe Desfray, "Modeling Enterprise Architecture with TOGAF", 2014)

[traceable:] "Information that is sufficient to make a determination about a specific aspect of an individual's activities or status." (NIST SP 800-122)

"The ability to identify related items in documentation and software, such as requirements with associated tests. " (ISTQB)

"The degree to which a relationship can be established between two or more products of the development process, especially products having a predecessor-successor or master-subordinate relationship to one another" (IEEE 1233-1998)
