Systems and software engineering - Software product Quality Requirements and Evaluation (SQuaRE) - Common Industry Format (CIF) for Usability: User requirements specification (ISO 25065:2019)

This document provides a framework and consistent terminology for specifying user requirements. It specifies the common industry format (CIF) for a user requirement specification including the content elements and the format for stating those requirements.
NOTE 1    A user requirements specification is the formal documentation of a set of user requirements, which aids in the development and evaluation of usable interactive systems.
In this document, user requirements refers to:
a)    user-system interaction requirements for achieving intended outcomes (including requirements for system outputs and their attributes);
b)    use-related quality requirements that specify the quality criteria associated with the outcomes of users interacting with the interactive system and can be used as criteria for system acceptance.
NOTE 2    ISO/IEC 25030 introduces the concept of quality requirements. The use-related quality requirements in this document are a particular type of quality requirement.
The content elements of a user requirements specification are intended to be used as part of documentation resulting from the activities specified in ISO 9241-210, and from human centred design processes, such as those in ISO 9241-220.
This document is intended to be used by requirements engineers, business analysts, product managers, product owners, and people acquiring systems from third parties.
The CIF series of standards addresses usability-related information (as described in ISO 9241-11 and ISO/IEC TR 25060).
NOTE 3    In addition to usability, user requirements can include other perspectives, such as human-centred quality introduced in ISO 9241-220, and other quality perspectives presented in ISO/IEC 25010, ISO/IEC TS 25011, and ISO/IEC 25030.
NOTE 4    While this document was developed for interactive systems, the guidance can also be applied in other domains.
This document does not prescribe any kind of method, lifecycle or process. The content elements of a user requirements specification can be used in iterative development which includes the elaboration and evolution of requirements (e.g. as in agile development).

System- und Software-Engineering - Qualitätskriterien und Bewertung von Systemen und Softwareprodukten (SQuaRE) - Allgemeines Industrieformat (CIF) zur Gebrauchstauglichkeit: Spezifikation der Nutzungsanforderungen (ISO 25065:2019)

Dieses Dokument bietet einen Rahmen und eine konsistente Terminologie für die Spezifikation von Nutzungsanforderungen. Es legt das allgemeine Industrieformat (CIF, en: Common Industry Format) für die Spezifikation von Nutzungsanforderungen inklusive der Inhaltselemente und des Formats für die Angabe dieser Anforderungen fest.
ANMERKUNG 1   Eine Spezifikation der Nutzungsanforderungen ist die formale Dokumentation eines Satzes an Nutzungsanforderungen, die die Entwicklung und Evaluierung gebrauchstauglicher interaktiver Systeme unterstützen.
In diesem Dokument beziehen sich Nutzungsanforderungen auf:
a)   Anforderungen an Benutzer-System-Interaktionen zum Erreichen beabsichtigter Ergebnisse (einschließlich Anforderungen an Systemausgaben und deren Attribute);
b)   nutzungsbezogene Qualitätsanforderungen, die die Qualitätskriterien in Verbindung mit den Ergebnissen der Interaktion von Benutzern mit dem interaktiven System festlegen und als Kriterium für die Systemabnahme verwendet werden können.
ANMERKUNG 2   ISO/IEC 25030 führt das Konzept von Qualitätsanforderungen ein. Die nutzungsbezogenen Qualitäts¬anforderungen in diesem Dokument sind ein bestimmter Typ von Qualitätsanforderungen.
Die Inhaltselemente einer Spezifikation der Nutzungsanforderungen sind zur Verwendung als Teil einer Dokumentation vorgesehen, die das Ergebnis der in ISO 9241 210 festgelegten Aktivitäten und der mensch¬zentrierten Gestaltungsprozesse wie die in ISO 9241 220 beschriebenen sind.
Dieses Dokument ist vorgesehen für die Verwendung durch Anforderungsingenieure, Wirtschaftsexperten, Produktmanager, Produktverantwortliche und Menschen, die Systeme von Dritten erwerben.
Die CIF Normenreihe behandelt Informationen bezüglich der Gebrauchstauglichkeit (wie in ISO 9241 11 und ISO/IEC TR 25060 beschrieben).
ANMERKUNG 3   Zusätzlich zur Gebrauchstauglichkeit können Nutzungsanforderungen auch andere Aspekte wie z. B. die in ISO 9241 220 eingeführte menschzentrierte Qualität und andere, in ISO/IEC 25010, ISO/IEC TS 25011 und ISO/IEC 25030 vorgestellte Qualitätsaspekte enthalten.
ANMERKUNG 4   Obwohl dieses Dokument für interaktive Systeme entwickelt wurde, können die enthaltenen Leitlinien auch in anderen Bereichen angewendet werden.
Dieses Dokument schreibt keine Methoden, Lebenszyklen oder Prozesse vor. Die Inhaltselemente einer Spezifikation der Nutzungsanforderungen können in der iterativen Entwicklung verwendet werden, was auch die Ausarbeitung und Weiterentwicklung von Anforderungen (z. B. in der agilen Entwicklung) mit einschließt.

Le présent document fournit un cadre et une terminologie cohérente pour spécifier les exigences utilisateur. Il spécifie le format industriel commun (CIF) applicable à une spécification d'exigences utilisateur, y compris les éléments de contenu et le format d'énonciation des exigences.
NOTE 1    Une spécification d'exigences utilisateur est la documentation formelle d'un ensemble d'exigences utilisateur, qui facilite le développement et l'évaluation de systèmes interactifs utilisables.
Dans le présent document, les exigences utilisateur font référence:
a)    aux exigences en matière d'interaction utilisateur-système pour atteindre les résultats escomptés (y compris les exigences pour les données de sortie système et leurs attributs);
b)    aux exigences de qualité liées à l'utilisation qui spécifient les critères de qualité associés aux résultats des utilisateurs interagissant avec le système interactif et peuvent être utilisées comme critères d'acceptation du système.
NOTE 2    L'ISO/IEC 25030 introduit le concept d'exigences de qualité. Les exigences de qualité liées à l'utilisation figurant dans le présent document sont un type particulier d'exigences de qualité.
Les éléments de contenu d'une spécification d'exigences utilisateur sont destinés à être utilisés dans le cadre de la documentation résultant des activités spécifiées dans l'ISO 9241-210 et des processus de conception centrée sur l'opérateur humain, tels que ceux de l'ISO 9241-220.
Le présent document est destiné à être utilisé par les spécialistes des spécifications d'exigences, les analystes commerciaux, les chefs de produit, les responsables produits et les personnes qui acquièrent des systèmes auprès de tiers.
La série de normes CIF traite des informations liées à l'utilisabilité (comme décrit dans l'ISO 9241-11 et l'ISO/IEC TR 25060).
NOTE 3    Outre l'utilisabilité, les exigences utilisateur peuvent inclure d'autres perspectives, comme la qualité centrée sur l'opérateur humain introduite dans l'ISO 9241-220 et d'autres perspectives de qualité présentées dans l'ISO/IEC 25010, l'ISO/IEC TS 25011 et l'ISO/IEC 25030.
NOTE 4    Bien que le présent document ait été développé pour des systèmes interactifs, les recommandations peuvent également être appliquées dans d'autres domaines.
Le présent document n'impose aucun type de méthode, cycle de vie ou processus. Les éléments de contenu d'une spécification d'exigences utilisateur peuvent être utilisés pour le développement itératif, qui comprend l'élaboration et l'évolution des exigences (par exemple, comme pour le développement agile).
