- 1Acceptance criteria, Abnahmekriterien, auch: AkzeptanzkriterienIn agile: Criteria that the implementation of a ↑user story must satisfy in order to be accepted by the ↑stakeholders.
Note: Acceptance criteria may also be written for ↑backlog items other than user stories. - 2Requirements negotiation, Abstimmung von Anforderungen (auch: Verhandlung von Anforderungen)A ↑process where ↑stakeholders are working toward reaching an agreement to resolve ↑requirements conflicts.
- 3AdequacyThe degree to which a ↑requirement expresses the ↑stakeholders' true and agreed desires and needs (i.e., those they had actually in mind when stating the requirement).
- 4Agile1. In general:
(a) Able to move quickly and easily.
(b) Quick, smart, and clever.
2. In software development: A development approach which builds a product ↑incrementally by dividing work into ↑iterations of fixed duration (↑timeboxes).
Note: Agile development is characterized by focusing on delivering a working product in each iteration, collaboration with ↑stakeholders with frequent feedback and adaptation of plans after each iteration based on feedback and changed ↑requirements. - 5ActorA person in some ↑role, a ↑system or a technical device in the context of a subject under consideration that interacts with that subject.
Note: In RE, the subject under consideration typically is a ↑system. In testing, it may be a test ↑object. - 6Activity diagramA diagram type in ↑UML which models the flow of actions in some part of a ↑system, including ↑data flows and areas of responsibility where necessary.
- 7Activity modelA ↑model of the flow of actions in some part of a ↑system.
- 8ModifiabilityThe degree to which a ↑work product or ↑system can be modified without degrading its ↑quality.
- 9Change requestIn RE: A well-argued request for changing one or more ↑baselined ↑requirements.
- 10Change control boardA committee of ↑customer and ↑supplier representatives that decides on ↑change requests.
Abbreviation: CCB
Note: The Change control board should not be confused with a change advisory board, which is a committee that evaluates change requests for a ↑system in operation and typically has no decision power. - 11Change managementA controlled way to effect or deny a requested change of a ↑work product.
- 12Requirement1. A need perceived by a ↑stakeholder.
2. A capability or property that a ↑system shall have.
3. A documented representation of a need, capability or property. - 13Kind of requirementA classification of requirements according to their kind into ↑system requirements (consisting of ↑functional requirements, ↑quality requirements and ↑constraints), project requirements, and process requirements.
Notes:
1. RE is primarily concerned with system requirements.
2. Quality requirements and constraints are also called ↑non-functional requirements. - 14Requirements documentA document consisting of a ↑requirements specification.
Note: Requirements document is frequently used as a synonym for requirements specification. - 15Requirements elicitation, AnforderungsermittlungThe process of seeking, capturing and consolidating ↑requirements from available ↑sources, potentially including the re-construction or creation of requirements.
- 16Requirements conflict1. A situation where two or more ↑requirements cannot be satisfied together.
2. A situation where two or more ↑stakeholders disagree about certain ↑requirements.
Note: Requirements conflicts have to be solved by ↑requirements negotiation. - 17Requirements managementThe process of managing existing ↑requirements and requirements-related ↑work products, including the storing, changing and tracing of requirements (↑traceability).
- 18Requirements sourceThe source from which a ↑requirement has been derived.
Note: Typical sources are ↑stakeholders, documents, existing ↑systems and observations. - 19Requirements specificationA systematically represented collection of ↑requirements, typically for a ↑system, that satisfies given criteria.
Notes:
1. In some situations we distinguish between a ↑customer requirements specification (typically written by the ↑customer) and a ↑system requirements specification or ↑software requirements specification (written by the supplier).
2. Requirements specification may also denote the ↑process of specifying (↑eliciting, documenting and ↑validating) requirements. - 20Requirements templateA template for specifying ↑requirements.
Note: In RE, several forms of templates are used. ↑Phrase templates are used for specifying individual ↑requirements or ↑user stories. ↑Form templates can be used to specify ↑use cases or ↑quality requirements. ↑Document templates provide a predefined structure for ↑requirements documents.
