The term elicitation is used in books and research to raise the fact that good requirements cannot just be collected from the customer, as would be indicated by the name requirements gathering. Requirements elicitation is non-trivial because you can never be sure you get all requirements from the user and customer by just asking them what the ...
Conceptually, requirements analysis includes three types of activities: [citation needed] Eliciting requirements: (e.g. the project charter or definition), business process documentation, and stakeholder interviews. This is sometimes also called requirements gathering or requirements discovery.
Elicitation is the gathering and discovery of requirements from stakeholders and other sources. A variety of techniques can be used such as joint application design (JAD) sessions, interviews, document analysis, focus groups, etc. Elicitation is the first step of requirements development.
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 ...
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. A requirement is a capability to which a project outcome (product or service) should conform.

[ 2 ] A person who interacts with human subjects in order to elicit information from them may be called an elicitor , an analyst , experimenter , or knowledge engineer ...
Later development methods, including the Rational Unified Process (RUP) for software, assume that requirements engineering continues through a system's lifetime. Requirements management , which is a sub-function of Systems Engineering practices, is also indexed in the International Council on Systems Engineering (INCOSE) manuals.
Rome Laboratory, the developer of REE, intended that to support their internal requirements gathering methodology. Their method has three main parts: Elicitation from various sources (users, interfaces to other systems), specification, and consistency checking; Analysis that the needs of diverse users taken together do not conflict and are ...
