Full title and description

IEC SRD 62559-4:2020 — Use case methodology - Part 4: Best practices in use case development for IEC standardization processes and some examples for application outside standardization. This Systems Reference Deliverable provides recommended procedures and good practices to draft, manage and reuse use cases to capture user requirements for systems used in IEC standardization and in enterprise projects.

Abstract

Part 4 of the IEC 62559 series complements the material in IEC TR 62559-1, IEC 62559-2 and IEC 62559-3 by describing best practices for the use-case redaction process: organizing drafting workshops, determining required skill sets, managing a use-case repository, and applying use cases in IEC committee work or in enterprise projects. It aims to make the IEC use-case methodology easier to apply across domains beyond smart energy, such as smart cities and active assisted living.

General information

• Publication date: March 27, 2020 (IEC publication record; some national bodies list adoption/publication dates in late March 2020).
• Publisher: IEC (Systems Reference Deliverable); also published/adopted by national bodies (for example BSI as BS IEC SRD 62559-4:2020).
• ICS / categories: 29.020 (Electrical engineering in general / system aspects).
• Edition / version: Edition 1.0 (2020).
• Number of pages: 38 pages in the IEC PDF edition (national publications list slightly different page counts in some reproductions).

Scope

This document specifies best practices for an entity to engage in a use-case redaction process to determine and describe user requirements for systems based on business needs. It covers workflows for drafting use cases, recommended participant roles and skill sets, processes for maintaining and curating a use-case repository, and guidance on how to use use cases effectively in IEC standardization projects or in enterprise-level requirements engineering. The guidance is intended to be generic so it can be applied across multiple domains.

Key topics and requirements

• Guidance on structuring and drafting use cases (narratives, primary/secondary actors, success and alternate scenarios).
• Recommended team composition and skill sets for effective use-case workshops (domain experts, requirements engineers, facilitators).
• Best practices for repository management: versioning, metadata, reuse and searchability of use cases.
• How to map use cases to IEC technical work (linking to TR/parts 1–3 and to domain-specific complementary standards).
• Recommendations for iterative drafting, validation, and traceability of requirements derived from use cases.

Typical use and users

Primary users are standards developers and IEC technical committees, systems engineers, requirements engineers, business analysts, and project leads who need a standardized approach to capture and manage functional requirements via use cases. It is also useful to enterprises and system architects wanting to align internal requirements practices with IEC standardization methods.

Related standards

IEC SRD 62559-4:2020 is part of the IEC 62559 family (Use case methodology) and complements IEC TR/62559-1, IEC 62559-2 and IEC 62559-3. It can be used alongside domain-specific IEC standards that reference or adapt the use-case methodology (for example work in the IEC SyC Smart Energy and related series).

FAQ

Q: What is this standard?

A: IEC SRD 62559-4:2020 is a Systems Reference Deliverable that documents best practices for developing and managing use cases to capture user requirements for systems in IEC standardization and in enterprise projects.

Q: What does it cover?

A: It covers the use-case drafting process, recommended team roles and skills, repository and lifecycle management for use cases, and guidance on applying use cases in standardization and enterprise contexts.

Q: Who typically uses it?

A: Standards developers, IEC technical committees, systems and requirements engineers, business analysts, and project teams seeking a standardized approach to document and reuse functional requirements.

Q: Is it current or superseded?

A: As published by IEC in 2020 it is current; the IEC webstore records a stability date through 2027 for this publication (i.e., the document will remain unchanged, be reconfirmed, withdrawn or revised by that date). National adoptions may show slightly different publication metadata.
