Before requirements can be analyzed, modeled, or specified they must be gathered through an elicitation process. Requirements elicitation is a part of the requirements engineering process, usually followed by analysis and specification of the requirements. Commonly used elicitation processes are the stakeholder meetings or interviews. [2]
Requirements inception or requirements elicitation – Developers and stakeholders meet; the latter are inquired concerning their needs and wants regarding the software product. Requirements analysis and negotiation – Requirements are identified (including new ones if the development is iterative), and conflicts with stakeholders are solved.
The activities related to working with software requirements can broadly be broken down into elicitation, analysis, specification, and management. [3] Note that the wording Software requirements is additionally used in software release notes to explain, which depending on software packages are required for a certain software to be built ...
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).
Analyzing requirements: determining whether the stated requirements are clear, complete, unduplicated, concise, valid, consistent and unambiguous, and resolving any apparent conflicts. Analyzing can also include sizing requirements. Requirements analysis can be a long and tiring process during which many delicate psychological skills are involved.
Requirements engineering may involve a feasibility study or a conceptual analysis phase of the project and requirements elicitation (gathering, understanding, reviewing, and articulating the needs of the stakeholders) and requirements analysis, [10] analysis (checking for consistency and completeness), specification (documenting the ...
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 ...
Numbers are only assigned to the high level requirements; sub-numbers are assigned to the mid- and low-level requirements since they are extensions of the high level requirements. For example, if the requirements for a web shopping cart state that the application must be able to calculate the tax for the specific state and/or province of the ...
