Use case methodology - Part 2: Definition of use case template, actor list and requirement list
This part of IEC 62559 “Use case methodology” 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.

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.
Odločitveni postopki - 2. del: Opredelitev odločitvenih postopkov s seznamom zahtev in pripadajočih uporabnikov (IEC 62559-2:2015)
Ta del standarda IEC 62559 »Odločitveni postopki« določa strukture odločitvenih postopkov, seznam zahtev in pripadajočih uporabnikov ter odnose med njimi. V tem dokumentu je standardizirani vzorec za opis postopkov določen za različne potrebe, kot je uporaba v organizacijah za standardizacijo za razvoj standardov ali v okviru projekta za razvoj sistema. Ta dokument je bil razvit za splošno uporabo na različnih področjih in v različnih sistemih. V tem dokumentu je kot primer uporabljen energetski sistem/pametno omrežje, saj je bilo to eno prvih področjih uporabe za ta odločitveni postopek, vendar je to splošno predlogo mogoče uporabiti tudi na drugih področjih uporabe, ki se razlikujejo od energetskih sistemov (npr. pametni dom ali elektro-mobilnost). Motivacija, osnovne informacije o primerih uporabe, priporočila za ravnanje v postopkih in postopki za opis primerov uporabe znotraj standardizacije in v zvezi z osrednjim repozitorijem odločitvenih postopkov so opisani v IEC 62559-1.

USE CASE METHODOLOGY –
Part 2: Definition of the templates for use cases,
actor list and requirements list
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.

INTRODUCTION
For complex systems, the use case methodology supports a common understanding of
functionalities, actors and processes across different technical committees or even different
organizations. Developed as software engineering tool, the methodology can be used to
support the development of standards as it facilitates the analysis of requirements in relation to
new or existing standards. Further arguments for the use case methodology and background
information are available in IEC 62559-1.
Figure 1 provides an overview of the intended first parts of the IEC 62559, mainly describing
the relation between IEC 62559-2 and IEC 62559-3.

IEC 62559-1 – Concept and processes in standardization
IEC 62559-1 is the basis for a common use case repository in order to gather use cases within
IEC on a common collaborative platform. This repository will also be used to organize a
harmonization of use cases in order to provide broadly accepted generic use cases as basis for
the further standardization work. It describes processes and provides basics for the use case
methodology like terms or use case types.
IEC 62559-2 – Definition of the templates for use cases, actor list and requirements list
IEC 62559-2 defines the structure of a use case template, an actor list and a list for
requirements. The document is mainly based on the previous IEC PAS 62559 specification and
shall be read together with IEC 62559-1.

IEC 62559-3 – Definition of use case template artefacts into an XML serialized format
Based on IEC 62559-2, IEC 62559-3 defines the required core concepts and their serialization
into an XML format of a use case template, an actor list and a list for detailed requirements.
The XML format is used to transfer the content of the template to other engineering systems
(e.g. UML modelling tools). These documents are developed using the energy system and
Smart Grids as examples, but they are general enough to be transferred to other domains and
systems. It is intended to develop a UML profile definition based on this part in the future.
Motivation
The International Standard IEC 62559 "Use case methodology" is needed to fulfill the SG3
decision 7 made by the SMB at its February 2010 meeting (SMB/4204/DL, Decision 137/10)
requesting the urgent delivery of a generic use case repository for all Smart Grid applications.
Nevertheless, the use case methodology described in this document is intended for a broader
application within standardization exceeding Smart Grid systems.
More and more complex systems such as Smart Grids or Smart Cities are raising the question
of managing system level requirements, which have to be fed by many domains of expertise (in
standardization related to different Technical Committees (TCs)), and which have to be broken
down further and shared by many TCs in charge of specifying standards to support these
system level functions.
One way to handle this transversality efficiently is to set some common methods and terms.
The use case methodology is the current state of art and supports further engineering
activities.
The use case methodology offers a unique way for sharing ideas and requirements of new use
cases or business cases between many experts/TC's with different backgrounds: e.g. domain
experts with knowledge about energy systems or business processes on one hand and system-
/IT-experts defining exchanged information and communication on the other hand. In the
requirement development process, domain experts are providing general ideas and functional
requirements. The main goal is for system experts to detail down these use cases to a level
they can be used to specify interfaces, dedicated functionality, data and service model
exchange. However, safety- or EMC-experts (as examples) may also make use of the
described use cases, their terminology and identified requirements.
However, the starting point is to set up a frame for consistency within IEC helping IEC
members to provide use cases in a consistent manner – this standard shall serve as basis for
use case repositories in order to gather, administrate, maintain, and evaluate use cases.
Within IEC, a use case repository shall be used as common collaborative platform for use case
elaboration and to organize a harmonization of use cases in order to provide broadly accepted
generic use cases as basis for further standardization work.
But the use case template defined in this document may serve not only for the development of
standards, but also – as it was the original purpose of the previous IEC PAS 62559:2008 (refer
to IEC 62559-4) – as a helpful means for the realization of projects within the area of complex
systems. Also other applications, which need the benefits of a structured requirements
development and formalized description of functionality, may make use of the suggested
template.
The use case methodology has to be seen as a process which starts with the definition of
business ideas, goals and requirements, detailing these in use case descriptions. This
information can be used as a basis to identify/link reference architectures describing the types
of components used, and going further down to an analysis for the further standardization
process.
---------------------- Page: 10 ----------------------
IEC 62559-2:2015 © IEC 2015 – 7 –
Further developments regarding the use case template are expected. These developments are
mainly related to information, which is required in the use case description for further analysis,
and which can be mapped to other information (e.g. to a reference architecture, IT security
methods, standards and data models). Partly this is considered in the suggested template of
this standard. Further relations will be described separately as they are still under development
and they might be considered for the further development of the IEC use case repository.

USE CASE METHODOLOGY –
Part 2: Definition of the templates for use cases,
actor list and requirements list
1 Scope
This part of IEC 62559 “Use case methodology” 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.
