Introduction
[1]
ISO 31700-1 provides high-level requirements and recommendations for organizations using privacy
by design in the development, maintenance and operation of consumer goods and services. These are
grounded in a consumer-focused approach, in which consumer privacy rights and preferences are
placed at the heart of product development and operation.
Use case help to identify, clarify and organize system requirements related to a set of goals, by
illustrating a series of possible sequences of interactions between stakeholder(s) and system(s) in a
particular ecosystem.
[2]
The use cases in this document use a template that is based on IEC 62559-2 while enabling a focus on
privacy by design challenges and on the ISO 31700-1 requirements.
Although there are a wide range of use cases, this document provides three sample use cases to help
further understand the implementation of ISO 31700-1: on-line retailing, a fitness company and smart
locks.

5.3 Viewpoints in the use cases
5.3.1 General
The viewpoints presented here are shown in the sequence diagrams of the use cases in Clause 7.
5.3.2 Consumer product viewpoint
Consumer products and associated organisational practices protect consumers’ privacy when the
product is in use and throughout the PII lifecycle while the PII is under the organisation’s purview.
Considering how a product is likely to be used in practice, during product development, can require a
number of different contexts and situations to be evaluated. Different users with different capabilities
are catered for. This applies as the product, once in the possession of a consumer user, is operated in
unconstrained circumstances where the consumer’s understanding and abilities can, and often do, vary
considerably.
For each type of use the precise definition of use is coupled with an accurate description of how the
product and any associated organisational processes would operate so as to protect privacy.
Finally, consumer use can change over time and vary between cultures or demographic groups.
5.3.3 Engineering framework viewpoint
The development and management of privacy controls is an essential part of the engineering of
consumers products. The resulting engineering framework combines:
[3]
— processes based on standards such as ISO/IEC/IEEE 15288 ;
— extensions of such processes that integrate privacy engineering. These extensions can be based on
[5] [7]
ISO/IEC TR 27550, with the support of frameworks such as the NIST Privacy Framework, the
[6]
use of OASIS PMRM to operationalize privacy principles;
[1]
— the integration of the consumer product viewpoint, which is supported by ISO 31700-1 .
NOTE An additional reference to OASIS PMRM is under development: ISO/IEC 27561, Information technology
— Privacy operationalisation model and method for engineers — POMME
5.3.4 Ecosystem viewpoint
Consumer products involve two ecosystems:
— the supply chain, i.e., the ecosystem associated with the system lifecycle process. This involves
organisation and contractual activities on the privacy capabilities provided by third parties;
— the data space, i.e., the ecosystem associated with users and providers of data. This involves
organisation and contractual activities on data sharing.
6 Use case analysis
6.1 General
A use case template was developed to help illustrate, in a consistent manner, the use case examples. The
template is structured to provide the information that illustrates the use of ISO 31700-1.
— The entries for the main narrative are general. They include ID: use case name; description of
product, service or process; privacy protection goal; ecosystem and systems of interest; users,
stakeholders; PII; purpose; and use case narrative.
— The entries for the extended narratives follow the requirements of ISO 31700-1: general requirements;
consumer communication requirements; risk management requirements; development, deployment
and operations of designed privacy controls; and end of PII lifecycle requirements.
