IEC 62559-2:2015

Use case methodology - Part 2: Definition of the templates for use cases, actor list and requirements list

IEC 62559-2:2015 defines the structure of a use case template, template lists for actors and requirements, as well as their relation to each other. In this document, a standardized template for the description of use cases is defined for various purposes like the use in standardization organizations for standards development or within development projects for system development. This document was developed for general application in various domains and systems. The energy system/smart grid is used as example in this document as it was one of the first usage areas for this use case template, but this general template can be applied in other usage areas different from energy systems as well (e.g. smart home or electro-mobility). The motivation, background information on use cases, recommendations for the handling of use cases and the processes for the description of use cases inside standardization and in relation to a central use case repository is described in IEC 62559-1. This first edition cancels and replaces IEC PAS 62559:2008 which had been published together with EPRI. Main content of the former PAS will be transferred to the new IEC 62559-4.

Méthodologie des cas d'utilisation - Partie 2: Définition du formulaire type de modèle de cas d'utilisation, de la liste d'acteurs et de la liste d'exigences

L'IEC 62559-2:2015 définit la structure d'un formulaire type de modèle de cas d'utilisation, les listes d'acteurs et d'exigences et leurs relations respectives. Dans le présent document, un modèle normalisé pour la description des cas d'utilisation est défini pour diverses fins comme l'utilisation dans les organisations de normalisation pour le développement de normes ou dans les projets de développement pour le développement de systèmes. Le présent document a été développé pour une application générale dans divers domaines et systèmes. Le système énergétique/réseau électrique intelligent est utilisé comme exemple dans le présent document car il s'agit d'un des premiers domaines d'utilisation pour ce formulaire type de modèle de cas d'utilisation, mais ce modèle général peut également être appliqué dans d'autres domaines d'utilisation différents des systèmes énergétiques (par exemple, maison intelligente ou électromobilité). La motivation, les informations générales sur les cas d'utilisation, les recommandations relatives à l'utilisation des cas d'utilisation et les processus de description des cas d'utilisation au sein de la normalisation et en relation avec un référentiel central de cas d'utilisation sont décrits dans l'IEC 62559-1. Cette première édition annule et remplace l'IEC PAS 62559:2008 parue avec l'EPRI. Le contenu principal des PAS précédentes est transféré vers la nouvelle IEC 62559-4.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62559-2 has been prepared by IEC technical committee 8: Systems
aspects for electrical energy supply.
This first edition cancels and replaces IEC PAS 62559:2008 which had been published together
with EPRI. Main content of the former PAS will be transferred to the new IEC 62559-4.
IEC 62559-1 to IEC 62559-3 are now more related to the application of the use case
methodology in standardisation. In this document, a revised and updated template is provided.
