Full title and description

Use case methodology - Part 2: Definition of the templates for use cases, actor list and requirements list. This part of IEC 62559 defines a standardized structure for a use-case template together with associated actor and requirements lists to support consistent documentation of user needs across domains (energy/smart grid is used as the primary example, while the template is generic and applicable to other areas such as smart home and e-mobility).

Abstract

IEC 62559-2:2015 specifies the fields, structure and inter-relationships for documenting use cases, for maintaining an actor glossary and for linking requirements to use-case elements. The objective is to provide a common template that supports standardization work and system development by making use-case descriptions consistent, comparable and machine-processable where needed. The document accompanies guidance given in other parts of the IEC 62559 family.

General information

• Status: Published (International Standard / adopted as EN 62559-2 in Europe and national variants).
• Publication date: 2015-04-30 (IEC publication).
• Publisher: International Electrotechnical Commission (IEC); adopted nationally/regionally by standards bodies (EN/BSI/AENOR implementations exist).
• ICS / categories: 29.020 — Electrical engineering in general.
• Edition / version: Edition 1.0 (2015).
• Number of pages: 118 pages in the IEC base publication (national/adopted versions may show different pagination).

Scope

This part defines a standardized template for documenting use cases, a template for an actor list (actor glossary) and a template for a requirements list, together with the relationships among those lists and use-case descriptions. It is intended for use within standards development, system engineering projects and central use-case repositories; although examples come from the energy/smart-grid domain, the templates are designed to be domain-independent.

Key topics and requirements

• Formalized use-case template fields (identifiers, goals, pre/post-conditions, main and alternate flows, triggers, scenario variants, priority, etc.).
• Actor list (glossary) structure and recommended attributes for actors to ensure consistent naming and role definition across use cases.
• Requirements list template and linkage mechanisms to connect requirements to specific use-case elements.
• Guidance on relationships between use cases, actors and requirements to support traceability and reuse in standards and projects.
• Examples and application notes with emphasis on energy/smart-grid scenarios (used as illustrative examples but not limiting the template’s applicability).

Typical use and users

Product managers, systems engineers, standards authors, requirements engineers, domain experts (notably in energy and smart grids), and integrators who need a consistent, repeatable method for capturing and exchanging use-case information. The standard is also used by projects and by organizations maintaining central use-case repositories to harmonize descriptions and improve traceability between use cases and requirements.

Related standards

IEC 62559-2 is part of the IEC 62559 use-case methodology family. IEC PAS 62559:2008 (the earlier Publicly Available Specification) was replaced by the IEC 62559 series; parts of the original PAS were redistributed into the newer parts of the series. EN/BS national/adopted versions (EN 62559-2, BS EN 62559-2, etc.) follow the same content with national implementation details.

FAQ

Q: What is this standard?

A: IEC 62559-2:2015 defines standardized templates for describing use cases, for maintaining an actor list and for a requirements list, enabling consistent documentation and traceability between use cases and requirements across projects and standards work.

Q: What does it cover?

A: It covers the structure and required fields of the use-case template, the structure of actor and requirements lists, and how these elements relate to each other. Examples focus on energy/smart-grid scenarios, but the templates are intentionally generic.

Q: Who typically uses it?

A: Standards developers, systems and requirements engineers, project teams creating system specifications, and organizations running use-case repositories — particularly in energy/smart-grid projects but also in other domains like smart home and electric mobility.

Q: Is it current or superseded?

A: IEC 62559-2:2015 is the published first edition (2015). It replaced IEC PAS 62559:2008 as part of the restructured IEC 62559 series; the IEC webstore entry lists the standard as published with a stability date noted in the publication metadata. For the absolute current status or any amendments after 2015, consult the issuing body or national standards organization.

Q: Is it part of a series?

A: Yes — it is Part 2 of the IEC 62559 use case methodology series. Other parts address background, processes, and the transfer of content from the earlier PAS into the series; national/adopted versions carry the same structure under EN/BS/UNE identifiers.

Q: What are the key keywords?

A: Use case, template, actor list, requirements list, traceability, smart grid, IEC 62559.
