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.
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 or www.iec.ch/members_experts/refdocs).
ISO and IEC draw attention to the possibility that the implementation of this document may involve the
use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity, or applicability of any
claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had not
received notice of (a) patent(s) which may be required to implement this document. However, implementers
are cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall not be held
responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www.iso.org/iso/foreword.html.

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 7, Software and systems engineering.
This first edition cancels and replaces ISO/IEC TR 29110-5-1-1:2012, which has been technically revised.
The main changes are as follows:
— Many task statements have been reworded to facilitate their understanding. Some task statements are
deleted to make this Entry profile light-weighted and suitable for streamlining to the Basic profile.
— Conditional tasks have been added to develop optional work products (e.g. change requests) that have
been requested by a customer. This notation replaces the ‘Optional’ notation [e.g. *(optional) used in the
first edition that caused ambiguities].
— Terms have been added to Clause 3 such that this document is self-contained.
— A few terms have been modified to align this document with the updated version of standards such as
ISO/IEC/IEEE 12207 and ISO/IEC/IEEE 15289.
— NOTEs have been added for giving additional information intended to assist the understanding or use of
the text of the document.
A list of all parts in the ISO/IEC 29110 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards
body. A complete listing of these bodies can be found at www.iso.org/members.html and

Introduction
0.1  Introduction to the ISO/IEC 29110 series
For the purpose of the ISO/IEC 29110 series, a very small entity (VSE) is an enterprise, organization (e.g.
government agency, non-profit organization), department or project having up to 25 people. Many VSEs
develop and/or maintain systems and the software components used in those systems, either as independent
products or incorporated into the larger system. Due to this, a recognition of VSEs as suppliers of high-
quality products is required.
VSEs around the world are creating valuable products and services. According to the World Bank, small and
medium enterprises (SMEs) account for about 90 % of enterprises worldwide. According to the Organisation
for Economic Co-operation and Development (OECD), SMEs represent 99 % of all businesses and generate
about 60 % of employment. Almost one person out of three is employed in a micro firm with less than 10
employees. The European Union reports that micro firms, with fewer than 10 persons, account for 93,5 % of
all enterprises and small firms, with 10 to 49 employees, account for 5,5 % of all enterprises. The challenge
facing OECD governments is to provide a business environment that supports the competitiveness of this
large heterogeneous business population and that promotes a vibrant entrepreneurial culture.
From studies and surveys conducted, it is clear that the majority of International Standards do not address
the needs of VSEs. Implementation of and conformity with these standards is difficult, if not impossible.
Consequently, VSEs have no, or very limited, ways to be recognized as entities that produce quality systems/
system elements, including software in their domain. Therefore, VSEs are excluded from some economic
activities.
It has been found that VSEs find it difficult to relate International Standards to their business needs and to
justify the effort required to apply standards to their business practices. Most VSEs can neither afford the
resources in terms of a number of employees, expertise, budget and time, nor do they see a net benefit in
establishing over-complex systems or software life cycle processes. To address some of these difficulties,
a set of guidelines has been developed based on a set of VSE characteristics. The guidelines are based on
subsets of appropriate standards proce
