Technical product documentation (TPD) - Classification of requirements - Part 2: Classification based on severity and susceptibility (ISO 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 document 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).
