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 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 ...
If a requirement has sub-requirements, each sub-requirement must have at least two test cases. Keeping track of the link between the requirement and the test is frequently done using a traceability matrix. Written test cases should include a description of the functionality to be tested, and the preparation required to ensure that the test can ...
Unlike the major six tool capabilities (see above), the following categories are introduced for the list, which correlate closer with the product marketing or summarizes capabilities, such as requirements management (including the elicitation, analysis and specification parts) and test management (meaning verification & validation capabilities).
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.
Review of all requirements, design and code; Testing of executable object code; Code coverage analysis; Analysis of all code and traceability from tests and results to all requirements is typically required (depending on software level). This process typically also involves: Requirements based test tools; Code coverage analyzer tools
A traceability model, which uses behavior trees as a formal notation to represent functional requirements, reveals change impacts on different types of design constructs (documents) caused by the changes of the requirements. [28] The model introduces the concept of evolutionary design documents that record the change history of the designs.
Requirements Triage or prioritization of requirements is another activity which often follows analysis. [4] This relates to Agile software development in the planning phase, e.g. by Planning poker, however it might not be the same depending on the context and nature of the project and requirements or product/service that is being built.
