Systems and software engineering - Requirements for testers and reviewers of user documentation
ISO/IEC 26513:2009 supports the interest of software users in receiving consistent, complete, accurate, and usable documentation. It defines the process in which user documentation products are tested. ISO/IEC 26513:2009 is intended neither to encourage nor discourage the use of either printed or electronic (on-screen) media for documentation, or of any particular documentation testing or management tools or methodologies. ISO/IEC 26513:2009 specifies processes for use in testing and reviewing of user documentation. It is not limited to the test and review phase of the life cycle, but includes activities throughout the Information Management and Documentation Management processes. ISO/IEC 26513:2009 provides the minimum requirements for the testing and reviewing of user documentation, including both printed and on-screen documents used in the work environment by the users of systems software. It applies to printed user manuals, online help, tutorials, and user reference documentation. The order of clauses in ISO/IEC 26513:2009 does not imply that the software user documentation should be tested in this order. In each clause, the requirements are media-independent, as far as possible. The informative checklists found in Annexes A and B may be used at each phase of the documentation process to verify that the appropriate steps have been carried out, and that the finished product has acceptable quality. ISO/IEC 26513:2009 can be helpful for testing and reviewing the following types of documentation: documentation of products other than software, for example, hardware or devices; multimedia systems using animation, video, and sound; computer-based training (CBT) packages and specialized course materials intended primarily for use in formal training programs; documentation produced for installers, computer operators, or system administrators who are not end users; maintenance documentation describing the internal operation of systems software. ISO/IEC 26513:2009 is applicable to testers, reviewers, and other related roles, including a variety of specialists: usability testers, documentation reviewers, and subject-matter experts; information designers and architects who plan the structure and format of products in a documentation set; usability specialists and business analysts who identify the tasks the intended users will perform with the software. It can also be consulted by those with other roles and interests in the documentation process. Managers of the software development process or the documentation process should consider the testing of documentation as part of their planning and management activities. Project managers, in particular, have an important role in planning the testing and reviewing of documentation. Testing of the documentation is likely to highlight any defects or nonconformances in tools that are used to create or display on-screen documentation. Similarly, usability testing of the documentation is likely to highlight defects or nonconformances with the presentation or layout of documentation and associated graphics and other media. As a result, there are a number of roles that should be involved in the testing of documentation because their work affects the content, display or presentation of documentation for the user, for example, developers of tools for creating on-screen documentation, graphic designers producing material displayed as part of the documentation, and human-factors experts who identify principles for making documentation more accessible and easily used, also user interface designers and ergonomics experts working together to design the presentation of the documentation on-screen. In some organizations these roles may have different titles, or an individual may perform more than one of these roles. There are other roles that need to understand the test processes for the documentation, for example authors should understand the test processed for the documentation

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

Introduction
Anyone who uses application software needs accurate information about how the software will help the users
accomplish a task. The documentation might be the first tangible item that the users see, and so influences
the first impressions the users have of the product. If the information is supplied in a convenient form and is
easy to find and understand, the users can quickly become proficient at using the product. Therefore, well-
designed documentation not only assists the users and helps to reduce the cost of training and support, but
also enhances the reputation of the product, its producer, and its suppliers.
This International Standard addresses the evaluation and testing of user documentation. It applies to both
initial development and subsequent releases of the software and user documentation.
This International Standard is independent of the software tools that might be used to produce documentation,
and applies to both printed documentation and on-screen documentation. Much of its guidance is applicable to
user documentation for systems including hardware as well as to software user documentation.
This International Standard conforms with ISO/IEC 26514:2008 Systems and software engineering —
Requirements for designers and developers of user documentation, ISO/IEC 15288:2008, Systems and
software engineering — System life cycle processes, and ISO/IEC 12207:2008, Systems and software
engineering — Software life cycle processes. This International Standard was developed to assist those who
test and review software user documentation as part of the software life cycle process. This International
Standard defines the Documentation Management and Validation processes of ISO/IEC 12207:2008 from the
tester's standpoint. This International Standard may be used as a conformance or a guidance document for
products, projects and organizations claiming conformance to ISO/IEC 15288:2008 or ISO/IEC 12207:2008.

INTERNATIONAL STANDARD ISO/IEC 26513:2009(E)
Systems and software engineering — Requirements for testers
and reviewers of user documentation
1 Scope
This International Standard supports the interest of software users in receiving consistent, complete, accurate,
and usable documentation. This International Standard defines the process in which user documentation
products are tested.
This International Standard is intended neither to encourage nor discourage the use of either printed or
electronic (on-screen) media for documentation, or of any particular documentation testing or management
tools or methodologies.
This International Standard specifies processes for use in testing and reviewing of user documentation
(Clause 5). It is not limited to the test and review phase of the life cycle, but includes activities throughout the
Information Management and Documentation Management processes.
This International Standard provides the minimum requirements for the testing and reviewing of user
documentation (Clause 6), including both printed and on-screen documents used in the work environment by
the users of systems software. It applies to printed user manuals, online help, tutorials, and user reference
documentation.
The order of clauses in this International Standard does not imply that the software user documentation
should be tested in this order.
In each clause, the requirements are media-independent, as far as possible. The informative checklists found
in Annexes A and B may be used at each phase of the documentation process to verify that the appropriate
steps have been carried out, and that the finished product has acceptable quality.
This International Standard can be helpful for testing and reviewing the following types of documentation:
• documentation of products other than software, for example, hardware or devices;
• multimedia systems using animation, video, and sound;
• computer-based training (CBT) packages and specialized course materials intended primarily for use
in formal training programs;
• documentation produced for installers, computer operators, or system administrators who are not end
users;
• maintenance documentation describing the internal operation of systems software.
This International Standard is applicable to testers, reviewers, and other related roles, including a variety of
specialists:
• usability testers, documentation reviewers, and subject-matter experts;
• information designers and architects who plan the structure and format of products in a documentation
set;
© ISO/IEC 2009 – All rights reserved 1
• usability specialists and business analysts who identify the tasks the intended users will perform with
the software.
The International Standard can also be consulted by those with other roles and interests in the documentation
process.
Managers of the software development process or the documentation process should consider the testing of
documentation as part of their planning and management activities. Project managers, in particular, have an
important role in planning the testing and reviewing of documentation.
Testing of the documentation is likely to highlight any defects or nonconformances in tools that are used to
create or display on-screen documentation. Similarly, usability testing of the documentation is likely to
highlight defects or nonconformances with the presentation or layout of documentation and associated
graphics and other media. As a result, there are a number of roles that should be involved in the testing of
documentation because their work affects the content, display or presentation of documentation for the user,
for example, developers of tools for creating on-screen documentation, graphic designers producing material
displayed as part of the documentation, and human-factors experts who identify principles for making
documentation more accessible and easily used, also user interface designers and ergonomics experts
working together to design the presentation of the documentation on-screen. In some organizations these
roles may have different titles, or an individual may perform more than one of these roles.
There are other roles that need to understand the test processes for the documentation, for example authors
should understand the test processed for the documentation that they have produced and acquirers of
documentation prepared by another department or organization might want to know what testing has been
performed and the processes followed for the documentation that they are acquiring from a supplier.
This International Standard is intended for use in all types of organizations, whether or not a dedicated
documentation department is present. In all cases, it may be used as a basis for local standards and
procedures. Readers are assumed to have experience or general knowledge of testing or reviewing
processes.
This International Standard deals with the evaluation of documentation only, and not with the evaluation of the
software it supports. Documentation is also included in evaluation of the software product, as in the
ISO/IEC 25000 series of standards. In particular, ISO/IEC 25051:2006 Software engineering — Software
product Quality Requirements and Evaluation (SQuaRE) — Requirements for quality of Commercial-Off-The-
Shelf (COTS) software product and instructions for testing.
The works listed in the Bibliography provide additional guidance on the processes of managing, preparing,
and testing user documentation.
2 Conformance
This International Standard may be used as a conformance or a guidance document for projects and
organizations claiming conformance to ISO/IEC 15288:2008, Systems and software engineering — System
life cycle processes, ISO/IEC 12207:2008, Systems and software engineering — Software life cycle
processes or both.
2.1 Definition of conformance
When the selected software life cycle processes are tailored, the organization or project may claim
conformance to this International Standard for its documentation process.
Throughout this International Standard, "shall" is used to express a provision that is binding, "should" to
express a recommendation among other possibilities, and "may" to indicate a course of action permissible
within the limits of this International Standard. When using this International Standard as a guide, replace the
term “shall” with “should”.
2 © ISO/IEC 2009 – All rights reserved
This International Standard is meant to be tailored so that only necessary and cost-effective requirements are
applied. Tailoring may take the form of specifying approaches to comply with its mandatory requirements, or
altering its non-mandatory recommendations and approaches to reflect the particular software and
documentation product more explicitly. Tailoring decisions should be specified in the contract.
NOTE: ISO/IEC 12207:2008 Annex A defines the tailoring process.
Use of the nomenclature of this International Standard for the parts of user documentation (that is, chapters,
topics, pages, screens, windows, etc.) is not required to claim conformance.
2.2 Conformance situations
Conformance may be interpreted differently for various situations. The relevant situation shall be identified in
the claim of conformance:
a) When conformance is claimed for an organization, the organization shall make public a document
declaring its tailoring of the life cycle process;
NOTE 1: One possible way for an organization to deal with clauses that cite "the documentation plan" or the "test
plan" is to specify that they shall be interpreted in the project plans for any particular documentation project.
b) When conformance is claimed for a project, the project plans or the contract shall document the tailoring
of the documentation requirements;
NOTE 2: A project’s claim of conformance is typically specified with respect to the organization’s claim of
conformance.
c) When conformance is claimed for a multi-supplier program, it may be the case that no individual project
may claim conformance because no single contract calls for all the required activities. Nevertheless, the
program, as a whole, may claim conformance if each of the required activities are produced by an
identified party. The program plans shall document the tailoring of the required tasks, and their
assignment to the various parties, as well as the interpretation of any clauses of the standard that
reference "the contract".
This International Standard may be included or referenced in contracts or similar agreements when the parties
(called the acquirer and the producer or supplier) agree that the supplier shall deliver user documentation
testing or reviewing and editing services in accordance with the standard. This International Standard may
also be adopted as an in-house standard by a project or organization that decides to test or assess
documentation in accordance with it.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
NOTE: Throughout this International Standard, the term documentation refers to software user documentation. Use of
the terminology in this International Standard is for ease of reference and is not mandatory for conformance.

4 User documentation process within the systems/software life cycle
This clause covers the processes involved in testing and reviewing user documentation.
Testers and reviewers of software user documentation work within the life cycle processes of the software
product, which are defined in ISO/IEC 12207:2008, Software life cycle processes. The applicable processes
are the Software Implementation process of Software Qualification Testing, and the Software Support
Processes of Documentation Management and Validation. ISO/IEC 12207 also describes the activities of the
documentation management process:
• process implementation;
• development and review;
• production;
• maintenance.
Within the Documentation Management process described in ISO/IEC 12207:2008, review of the
documentation and approval of adequacy by authorized personnel prior to issue is described as part of the
design and development process. This includes review for format, technical content, and presentation style
against documentation standards. Within the Software Validation process and activities described in
ISO/IEC 12207:2008, the relevant activities are tested so that representative users can successfully achieve
their intended task, and that the product satisfies its intended use.
Therefore, testing and reviewing of the user documentation should be part of the same processes as the
product life cycle, and ideally performed in conjunction with the development of the software, so that the
software and the user documentation are tested, distributed, and maintained together. The testing of all the
documentation, including on-screen documentation and printed documentation, should be a part of the
development of the product as a whole, not a separate exercise. Although accurate user documentation
cannot be completed until the software product has been fully developed, the user documentation and the
product both benefit from concurrent development and testing.
Ideally, documentation testing is carried out in conjunction with the development of the software. Aspects of
the Measurement life cycle process from ISO/IEC 12207:2008 are also relevant to this International Standard.
The test process applies to software and documentation developed under both the classic documentation
development process (development of a new product with new user manual), and also more complex
circumstances, such as:
• a previously documented software product is being upgraded, offered in a new version or on different
operating system platforms, or customized as part of system integration requiring the revision of
previous documentation;
• previous documentation must be converted to a different format or different media, or in different
languages or versions, such as tutorials, online help, or advanced reference guides;
• previous documentation must be adapted or used as models for different products acquired or
supplied by an organization;
• previous documentation must be modified to adhere to new regulations, business process guidelines,
or compliance requirements.
Testing and reviewing software user documentation is greatly assisted by the presence of other
documentation produced during the software life cycle, such as a Documentation Plan, System Design
Document, System Test Plan, Release Records, and Problem Reports. Other documentation specific to the
8 © ISO/IEC 2009 – All rights reserved
documentation process may be produced, such as style guides and organizational procedures for content
management and documentation reviews.
NOTE: ISO/IEC 15289:2006 Systems and Software Engineering — Content of systems and software life cycle
process information products (Documentation) provides recommendations for the required documents throughout the
systems/software life cycle.
This International Standard is also related to the following standards: ISO/IEC 25000:2005 Software
Engineering — Software product Quality Requirements and Evaluation (SQuaRE) — Guide to SQuaRE and
ISO/IEC 14598, Information technology — Software product evaluation Parts 1-6, 1998-2001. These
standards describe the quality metrics characteristics of software and the evaluation process for ensuring
quality in a software product. The same processes may be used to ensure that the documentation meets the
required quality through the use of evaluation metrics.
For the sake of simplicity, this standard describes the life cycle as if there were a clear starting point for
developing documentation, and a clear end point. However, there is not a single sequence of activities that
might be followed in all cases for all products and all types of information. For example, implementation and
review activities are very closely inter-linked, as are testing and maintenance, and the way they link together
varies between projects.
5 Documentation evaluation process requirements, objectives, and constraints
5.1 General
The purpose of documentation evaluation is to ensure that documentation is acceptable for use. This clause
describes the processes of documentation evaluation in two forms: testing and reviewing. Documentation
evaluations are performed throughout the document's development, production, and maintenance.
Documentation evaluation shall be based on the required functions and qualities. Ultimate acceptance comes
from the end-users, but the managers, developers, testers, and maintainers must accept the quality before the
documentation can be released to the user. Evaluation of documentation quality depends on the recognition of
various perspectives for acceptability:
• manager's view. Managers might be more concerned with overall quality than with specific quality
characteristics. They might assign different weights to certain characteristics to reflect the business
needs of the organization, comparing the documentation to what is commercially available in the
market and what is less costly to produce. Managers should be aware that the quality of
documentation might appreciably affect costs for customer support and future sales.
• developer's view. Developers might be concerned with how the product operates in its innovative or
advanced functions, more than with how the product supports the users' tasks.
• tester's view. Testers might be concerned with how the product operates in its innovative or
advanced functions in the same way as other developers, but should have a better understanding of
how the product supports the users' tasks, and whether the documentation matches the product and
helps the user to accomplish tasks.
• maintainer's view. Those who will have to maintain the documentation systems will have special
requirements for quality in addition to those of other developers. They will be concerned with, for
example, the simplicity and clarity of the documentation structures, the ease with which new versions
of the documentation might be created, and portability to new technology for content management and
production.
• user’s view. Users are likely to measure quality in terms, such as inclusion of needed information,
reliability, and ease of finding information and applying it to accomplish needed tasks.

5.2 Documentation evaluation activities
Documentation evaluation shall include the following four activities: Plan, Do, Check, Act.
• Plan: The organization shall identify the requirements for acceptable performance or quality. The
organization shall prepare for the evaluation exercise by specifying the schedule, the resources
needed, how the evaluation will be carried out (test scenarios and scripts), how the results will be
measured and recorded, how the results will be analyzed, and the pass/fail criteria for the evaluation.
• Do: The organization shall draw up test scenarios and scripts based on the requirements from the
planning stage. The organization shall then evaluate the documentation against the requirements,
using measures, and record the results. Tests may be carried out by members of the project team
during development, following the test scripts to ensure tests are systematic and complete.
• Check: The organization shall analyze and report the results of the evaluation, recommending next
steps.
• Act: Based on the evaluation results and recommendations, the organization shall revise the
documentation and the product, and determine if further evaluation cycles are needed.
NOTE: Revisions may entail changes in the project schedule and documentation plan or even changes in the
requirements to produce acceptable results. For example, documentation of advanced functions might be deferred until a
later project phase, or product release dates might be deferred until acceptable documentation is produced.
The documentation evaluation activities recommended in this International Standard should be carried out
under the control of the quality management system being used for the software product. Users of this
International Standard are recommended to operate a quality management system, which may be
independently assessed for ISO 9000 compliance.
5.3 Selection of an evaluation method
The evaluation method selected depends on a variety of factors including:
• the reasons for carrying out the evaluation;
• the phase in the life cycle at which the evaluation is being carried out;
• the resources available;
• the time available;
• the amount of information available about the documentation;
• the availability of users with the appropriate ranges of experience and skill;
• the availability of experts in documentation design;
• the availability of experts in usability.
Different methods may be used at different phases in the development, after the documentation is complete
and when the documentation has been used for a specified period. A combination of methods is likely to be
appropriate in each case.
5.4 Documentation review
The documentation review process as further detailed in 6.1 includes:
• editorial reviews of the documentation's structure, format, and style compared to plans, requirements,
and established standards;
• content reviews;
10 © ISO/IEC 2009 – All rights reserved
• topic coverage;
• technical accuracy (consistency with the product);
• safety (provision of critical information to protect against hazards or defects);
• legal, statutory and regulatory requirements.
5.5 Documentation test
Documentation test requirements shall be specific and measurable. The purpose of the test process is to
provide formal evidence that the user documentation:
• enables the users to accomplish their goals;
• meets the requirements and constraints, such as the documentation policy and standard formats and
styles set by the producer of the software product;
• is consistent with the software product; that is, the documentation is accurate, sufficient, and useful
NOTE: Consult Clause 11.1 in ISO/IEC 26514:2008. Systems and software engineering—Requirements for designers
and developers of user documentation for additional information on the completeness of documentation.
• meets usability requirements, that is, information is easy to find, easy to use, and easy to understand;
• meets the needs of the intended acquirer and end users of the software product and documentation.
The documentation test process, as further detailed in 6.2 to 6.6, includes:
• operational testing to ensure that the documentation performs correctly and responsively (for example,
on-screen documentation is appropriately linked to the software topic and navigation operation is
consistent and as expected; the index in printed documentation has accurate references);
• usability testing of documentation with the product, to determine whether the intended audience can
perform their tasks with the aid of the documentation.
5.6 Project requirements affecting documentation evaluation
The user documentation tester or reviewer shall gather or receive information about the testing of the whole
project, to understand the requirements that affect the testing of the documentation components.
Documentation testers and reviewers need the following information in order to plan the evaluation of the
documentation:
• who are the users, and in what contexts will they use the product?
• what formats will the documentation be provided in for the end user?
• are there users with special needs?
• what is the purpose of the software product? What will it do?
• is there a previous version? If so, which features have to be changed and which have to remain the
same?
• is the product standalone, or is it part of a suite of products?
• when will the documentation be available to assess and test?
• when will the testing need to be completed?
• will the documentation be available to test at the same time as the software?
• what types of documentation will be produced?
© ISO/IEC 2009 – All rights reserved 11
• what is the scope of the evaluation; that is, how much documentation needs to be tested?
• on what platforms will the product run at this release? Are there plans for other platforms later?
• is the product being developed for a specific organization or organizations? If so, are those
organizations the exclusive users?
• will localized or customized versions of the product be required?
• Will the documentation be translated into foreign languages? What languages?
Documentation testers need to know the following about the product development schedule:
• when will the alpha, beta, and acceptance testing start and be completed?
• when will the testing need to be completed?
• what is the delivery date for the finished product?
• what are the major dependencies between different activities in the overall project?
5.7 Resource requirements and planning
The documentation evaluator should obtain information on the planned or required tools for:
• reviewing the documentation;
• testing the documentation; including performing usability tests and tests of accessibility.
If the new product is part of a suite of products, consider the use of any tools already specified for testing
documentation for that suite.
In planning the evaluation of the documentation, the availability of resources should be considered. The
evaluation plan should include the time and effort to include acquisition of resources or services that are not
already available in the organization. A working model or prototype of the documentation should be provided
where testing is scheduled to take place before software or documentation development is complete. The
acquirer or project sponsor should provide people to participate in the usability tests. These people shall have
the same characteristics as the defined audience. The purpose of the test sha
