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).

Introduction
This document provides a specification for mapping the ISO/IEC/IEEE 12207 life cycle processes to the
ISO/IEC 33020 process attributes with the intent of demonstrating support for the levels 1 to 3 of the
ISO/IEC 33020 process capability measurement framework.
This document is primarily addressed to developers of process assessment models for the process quality
characteristic of process capability. It is also addressed to the lead assessor and other stakeholders, such as
the sponsor of the assessment, who need to be assured that the requirements of the ISO/IEC 33020 process
measurement framework have been met.
Within this document:
— Clause 4 provides a summary description of the relationship between the ISO/IEC 33020 process
attribute outcomes and the ISO/IEC/IEEE 12207 life cycle processes.
— Annex A extends the summary mapping in Clause 4 by providing details of the relationship between
the process attribute outcomes and the life cycle process outcomes. Links to the information items
listed in Annex C are identified. These details are provided for validating by inspection the relationships
between the process attribute outcomes of ISO/IEC 33020 and the ISO/IEC/IEEE 12207 life cycle process
outcomes.
— Annex B focuses on the relationships between the generic practices associated with ISO/IEC 33020 and
the task descriptions of ISO/IEC/IEEE 12207. These model elements are linked via the information item
characteristics listed in Annex C.
— Annex C provides a listing of the applicable information items and their characteristics.
— Annex D provides an overview of the key concerns arising from the application of ISO/IEC/IEEE 24774
when attempting to demonstrate objective relationships between process model elements.

4 Content of the process capability measurement framework
4.1 General
In ISO/IEC 33020:2019, Clause 5, the relationship between process attributes and process capability levels
is described.
Process capability is defined in ISO/IEC 33020:2019, Clause 5 on a six-point ordinal scale that enables process
capability to be assessed from the bottom of the scale, 'incomplete', through to the top end of the scale,
'innovating'. The scale represents increasing capability of an implemented process, from failing to achieve
the process purpose through to continually improving and able to respond to process change.
The relationship between the process capability levels and the process attributes is shown in Table 1. In
addition, a summary view is presented of the relationship of the process attributes to the life cycle processes
associated with ISO/IEC/IEEE 12207.
Two processes from ISO/IEC/IEEE 12207 do not appear in the list in Table 1, namely, the acquisition and
decision management processes. These outcomes of these processes do not have any discernible relationships
to the process attribute outcomes of ISO/IEC 33020.
Certain ISO/IEC/IEEE 12207 processes have been partitioned into sub processes, namely life cycle model
management, infrastructure management, human resource management, knowledge management, quality
management, measurement and quality assurance. This action has been taken to address outcomes in the
basic processes that deal with firstly, establishment concerns, and secondly, performance (or operational)

concerns. The 'establishment' outcomes of these sub processes are mapped to ISO/IEC 33020:2019 PA
3.1 concerns. The 'performance' concerns of the sub processes are mapped to either PA 3.2 or PA 3.3, as
appropriate.
As an example, with reference to ISO/IEC/IEEE 12207:2017, 6.2.1, life cycle model management, the basic
and sub process outcomes are presented in Table 1.
