Requirements traceability is a sub-discipline of requirements management within software development and systems engineering.Traceability as a general term is defined by the IEEE Systems and Software Engineering Vocabulary [1] as (1) the degree to which a relationship can be established between two or more products of the development process, especially products having a predecessor-successor ...
A requirements traceability matrix may be used to check if the current project requirements are being met, and to help in the creation of a request for proposal, [2] software requirements specification, [3] various deliverable documents, and project plan tasks. [4]
Requirements come from different sources, like the business person ordering the product, the marketing manager and the actual user. These people all have different requirements for the product. Using requirements traceability, an implemented feature can be traced back to the person or group that wanted it during the requirements elicitation.
The PMI guide Requirements Management: A Practical Guide recommends that a requirements tool should be identified at the beginning of the project, as [requirements] traceability can get complex and that switching tool mid-term could present a challenge. [3] According to ISO/IEC TR 24766:2009, [4] six major tool capabilities exist:
Traceability confirms that the requirement set satisfies the need (no more - and no less than what is required). To the above some add Externally Observable, that is, the requirement specifies a characteristic of the product that is externally observable or experienced by the user.
A traceability analysis is then used to ensure that each requirement is fulfilled by the source code, that each functional requirement is verified by test, that each line of source code has a purpose (is connected to a requirement), and so forth. Traceability analysis accesses the system's completeness.
Mauler explained how the FSMA helps agencies like the Food and Drug Administration investigate by allowing them to recall food and put a lot of traceability requirements for imported food to ...
Requirements analysis is critical to the success or failure of a systems or software project. [3] The requirements should be documented, actionable, measurable, testable, [4] traceable, [4] related to identified business needs or opportunities, and defined to a level of detail sufficient for system design.
