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]
From the list of requirements, we can identify related areas, whose functionality is similar. These areas are the test groups. For example, in a railway reservation system, anything related to ticket booking is a functional group; anything related with report generation is a functional group. In the same way, we have to identify the test groups ...
Processes are intended to support the objectives, according to the software level (A through D—Level E was outside the purview of DO-178B). Processes are described as abstract areas of work in DO-178B, and it is up to the planners of a real project to define and document the specifics of how a process will be carried out.
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.
Using requirements traceability, an implemented feature can be traced back to the person or group that wanted it during the requirements elicitation. This can, for example, be used during the development process to prioritize the requirement, [6] determining how valuable the requirement is to a specific user. It can also be used after the ...
For example, cold weather operation may require operation to be evaluated at temperatures below C using an environmental chamber. Evaluation of operation with a vehicle interface may require compatibility evaluation with a vibration test. Evaluation of an Internet store would require the system to take the user through a product purchase while ...
An example of a generic RFID chip. Some produce traceability makers use matrix barcodes to record data on specific produce. The international standards organization EPCglobal under GS1 has ratified the EPC network standards (esp. the EPC information services EPCIS standard) which codify the syntax and semantics for supply chain events and the secure method for selectively sharing supply chain ...
