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.
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 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).
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. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Introduction
The purpose of this document is to provide an International Standard that defines work product
reviews, such as inspections, reviews and walkthroughs that can be used at any stage of the software
and systems life cycle. It can be used to review any system or software work product. This document
defines a generic process for work product reviews that can be configured based on the purpose of the
review and the constraints of the reviewing organization. The intent is to describe a generic process
that can be applied both efficiently and effectively by any organization to any work product.
The main objectives of reviews are to detect issues, to evaluate alternatives, to improve organizational
and personal processes, and to improve work products. When applied early in the life cycle, reviews are
typically shown to reduce the amount of unnecessary rework on a project. The work product review
techniques presented in this document can be used at various stages of the generic review process to
identify defects and evaluate the quality of the work product.
Review documents that are produced during work product reviews are defined in Annex A.

Software and systems engineering — Work product reviews
1 Scope
This document establishes a generic framework for work product reviews that can be referenced and
used by all organizations involved in the management, development, test and maintenance of systems
and software. It contains a generic process, activities, tasks, review techniques and documentation
templates that are applied during the review of a work product. A work product is any artefact
produced by a process. This document defines work product reviews that can be used during any phase
of the life cycle of any work product. This document is intended for, but not limited to, project managers,
development managers, quality managers, test managers, business analysts, developers, testers,
customers and all those involved in the development, testing
