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]
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.
An elicitation technique is any of a number of data collection techniques used in anthropology, cognitive science, counseling, education, knowledge engineering, linguistics, management, philosophy, psychology, or other fields to gather knowledge or information from people.
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.
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.
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 ...
Different sources of requirements are discussed along with many elicitation techniques like questioning techniques, observation techniques, creativity techniques and artifact-based techniques. Conflict resolution is supported by a variety of consolidation techniques and clear guidelines as to which situation to use which technique.
Formal Requirements Elicitation Tool (FRET) is a requirements engineering tool. It was developed by the NASA Ames Research Center to specify complex safety-critical systems whose failure could result in loss of life, significant property damage, or environmental harm. [3] FRET is open-source software released under the NASA Open Source ...
