In agile: Criteria that the implementation of a ↑user story must satisfy in order to be accepted by the ↑stakeholders.
Acceptance criteria may also be written for ↑backlog items other than user stories.
A 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.
The 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).
Synonym: Agilität
1. 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 ).
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.
Synonym: Change Control Board
A committee of ↑customer and ↑supplier representatives that decides on ↑change requests .
Abbreviation: CCB
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.
In RE: A well-argued request for changing one or more ↑baselined ↑requirements.
A classification of requirements according to their kind into ↑system requirements (consisting of ↑functional requirements , ↑quality requirements and ↑constraints ), project requirements, and process requirements.
1. RE is primarily concerned with system requirements.
2. Quality requirements and constraints are also called ↑non-functional requirements .
The degree to which a ↑work product or ↑system can be modified without degrading its ↑quality .
1. 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.
1. A situation where two or more ↑requirements cannot be satisfied together.

Requirements conflicts have to be solved by ↑requirements negotiation.
A document consisting of a ↑requirements specification.
Requirements document is frequently used as a synonym for requirements specification.
Synonym: elicitation (of requirements)
The process of seeking, capturing and consolidating ↑requirements from available ↑sources, potentially including the re-construction or creation of requirements.
The process of managing existing ↑requirements and requirements-related ↑work products, including the storing, changing and tracing of requirements ( ↑traceability ).
Synonym: Verhandlung (von Anforderungen)
A ↑process where ↑stakeholders are working toward reaching an agreement to resolve ↑requirements conflicts.
The source from which a ↑requirement has been derived.
Typical sources are ↑stakeholders, documents, existing ↑systems and observations.
A systematically represented collection of ↑requirements , typically for a ↑system , that satisfies given criteria.
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.
Synonym: Anforderungsschablone
A template for specifying ↑requirements.
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.
Synonym: artifact
A recorded, intermediate or final result generated in a work ↑process .
