Technical product documentation (TPD) - Classification of requirements - Part 2: Classification based on severity and susceptibility (ISO/FDIS 24096-2:2024)
This document specifies a method for the classification of requirements based on severity and susceptibility. The classification method requires a system in line with the framework described in ISO 24096-1 to form a complete system.
This document:
— gives guidance on the needed elements for a consistent evaluation of the severity over time, and supports a company business model and its brand image;
— gives background to why additional parameters alongside severity are useful as a base for classification;
— adds susceptibility as a viable parameter along with severity;
— gives guidance on the methodology for classification requirements using severity and susceptibility.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
This document addresses classification of requirements. It is a framework for building a system to
enable classification of requirements and indication of the classification in the technical product
documentation (TPD) to support communication of the consequences of deviation from requirements.
This document has been elaborated mainly to be implemented within industry, e.g. the automotive and
aerospace industries. However, it could also be used in other engineering fields.
Classification of requirements is a tool by which subsequent parties and stakeholders can be informed of
the severity of consequences of non-conformity of requirements. This facilitates guiding of production
and quality assurance resources, for instance the work of purchasing, production planning, control and
revision. The classification system relies on an underpinning of procedures, regulatory framework and
contractual agreements for implementation and follow-up as present in all modern industry.
There are quite a few examples of industrial stakeholders which deploys their own or partially self-
developed system and methodology for classification of requirements. There has not been any ISO
document that pragmatically describes “what is” and “how to create” a classification system. With
these documents, the identified gap will be bridged. There is a great need within ISO, and external ISO,
to describe how to introduce and work with a classification system in an industrial and design context.
Knowledge of the consequences of non-conformity with requirements and actions taken to resolve the
source of the deviation from given requirements will have a positive effect on the product quality, user
safety and economy of the product The production and inspection resources can then be used where
they are most needed.
Annex A gives examples of classification with severity and susceptibility.
Annex B gives guidance on susceptibility.

Part 2:
Classification based on severity and susceptibility
1 Scope
This document describes a method for classification of requirements based on severity and
susceptibility. This classification method needs a system in line with the framework described in
ISO 24096-1 to form a complete system.
This document
— indicates the needed elements for a consistent evaluation of the severity over time, and supports a
company business model and its brand image;
— gives background to why more than severity is useful as a base for classification;
— adds susceptibility as a viable parameter along with severity;
— describes the methodology for classification requirements using severity and susceptibility.
