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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this Amendment may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to International Standard ISO 9241-1:1997 was prepared by Technical Committee ISO/TC 159,
Ergonomics, Subcommittee SC 4, Ergonomics of human-system interaction.
ISO 9241-1:1997/Amd.1:2001(E)
Introduction
ISO 9241 covers both the hardware and software ergonomic aspects of the use of visual display terminals. The
individual parts of ISO 9241, their interrelationships, and the expected users of the parts are described in the main
body of ISO 9241-1.
This Amendment deals particularly with the software parts of ISO 9241, i.e. ISO 9241-10 to ISO 9241-17. These
parts are concerned with the ergonomic design of software user interfaces.
The goal of this Amendment (complementing ISO 9241-1) is to help readers of ISO 9241-10 to ISO 9241-17 in
� gaining an overview on the content of ISO 9241-10 to ISO 9241-17,
� understanding the relationship between the individual software parts of ISO 9241,
� providing guidance on the relevance of individual parts to the development process, i.e. understanding where
and when to use the software parts of ISO 9241,
� understanding how to select and combine dialogue techniques which are described in ISO 9241-14 to
ISO 9241-17.
The ultimate beneficiary of ISO 9241-10 to ISO 9241-17 will be the end user at the VDT. It was the needs of these
users that provided the ergonomic recommendations in ISO 9241-10 to ISO 9241-17. Although it is unlikely that the
end user will read ISO 9241 or even know of its existence, its application should provide user interfaces that are
more usable, consistent and that enable greater productivity.

Description and application of software parts (in ISO 9241-10 to ISO 9241-17)
A.1 Structure of ISO 9241-10 to ISO 9241-17
A.1.1 Introduction
ISO 9241-10 to ISO 9241-17 cover software ergonomics issues such as:
� principles for human-computer dialogues (ISO 9241-10);
� the relevance of the context of use (users, tasks, environment) and the definition of usability in terms of
effectiveness, efficiency and satisfaction (ISO 9241-11);
� characteristics of presented information and recommendations for the presentation of information (ISO 9241-12);
� recommendations for user guidance; these apply to all dialogue techniques (ISO 9241-13);
� recommendations for the usage of dialogue techniques (ISO 9241-14 to ISO 9241-17).
The specification or design of human-computer dialogues should be driven by an understanding of the
requirements of the users, their tasks, the environment and the available technology. There are usually several
options and the final choice may be influenced by the desire for consistency (e.g. with existing organizational
practices or across a range of systems). Decisions about the overall suitability of human-computer dialogues can
be assisted by reference to standards containing general principles of dialogue design i.e. ISO 9241-10. Specific
recommendations for dialogue design are addressed in ISO 9241-14 to ISO 9241-17.
A.1.2 Relationship between ISO 9241-10 to ISO 9241-17
Figure A.1 illustrates the structure of ISO 9241-10 to ISO 9241-17, reflecting the nature of the individual parts in
terms of principles and recommendations.

A.1.3 ISO 9241-10 “Dialogue principles”
The purpose of ISO 9241-10 is to present high-level ergonomic principles that apply to the design of dialogues
between humans and information systems. ISO 9241-10 provides seven principles of good practice for the design
of the dialogue between the user and the interface software.
These seven principles are:
� suitability for the task;
� self-descriptiveness;
� controllability;
� conformity with user expectations;
� error tolerance;
� suitability for individualization;
� suitability for learning.
The principles given in ISO
