Requirements engineering (RE) [1] is the process of defining, documenting, and maintaining requirements [2] in the engineering design process. It is a common role in systems engineering and software engineering .
In systems engineering and software engineering, requirements analysis focuses on the tasks that determine the needs or conditions to meet the new or altered product or project, taking account of the possibly conflicting requirements of the various stakeholders, analyzing, documenting, validating, and managing software or system requirements.
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 management is the process of documenting, analyzing, tracing, prioritizing and agreeing on requirements and then controlling change and communicating to relevant stakeholders. It is a continuous process throughout a project.
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 ...
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).
Business requirements in the context of software engineering or the software development life cycle, is the concept of eliciting and documenting business requirements of business users such as customers, employees, and vendors early in the development cycle of a system to guide the design of the future system.
The purpose of Requirements Management (REQM) is to manage requirements of the project's products and product components and to ensure alignment between those requirements and the project's plans and work products. Specific Practices by Goal. SG 1 Manage Requirements SP 1.1 Understand Requirements; SP 1.2 Obtain Commitment to Requirements
