Introduction
0.1  General
The aim of this document is to develop and continually improve a railway quality management system
to ensure product quality including safety in the global railway sector, in order to satisfy customer
needs.
This document adds the supplemental railway sector specific requirements to ISO 9001:2015.
The content inside the boxed text of this document is ISO 9001:2015 text.
Whenever the ISO 9001:2015 text in this document refers to “quality management system”, this term
is understood hereinafter as “railway quality management system”, not limited to quality, so that it
encompasses all railway quality processes of the organization. Therefore, in the supplemental railway
sector specific requirements, the term “railway quality management system” is used outside the boxed
text.
Whenever the ISO 9001:2015 text refers to “this International Standard”, this applies to this document,
including the text outside the boxes.
Whenever this document refers to clause numbers, it is to be understood that all the requirements
under this clause including subclauses are to be considered.
Whenever this document refers to “safety”, the term is to be understood as “safety of products and
services”, not to be confused with “occupational safety”.
Whenever this document requires a process, this process can be either
— defined within a single process,
— combined with another process or other processes, or
— split in several processes
according to the railway quality management system defined by the organization.
ISO 9001:2015, Quality management systems — Requirements
0.1  General
The adoption of a quality management system is a strategic decision for an organization that can help
to improve its overall performance and provide a sound basis for sustainable development initiatives.
The potential benefits to an organization of implementing a quality management system based on this
International Standard are:
a) the ability to consistently provide products and services that meet customer and applicable
statutory and regulatory requirements;
b) facilitating opportunities to enhance customer satisfaction;
c) addressing risks and opportunities associated with its context and objectives;
d) the ability to demonstrate conformity to specified quality management system requirements.
This International Standard can be used by internal and external parties.
It is not the intent of this International Standard to imply the need for:
— uniformity in the structure of different quality management systems;
— alignment of documentation to the clause structure of this International Standard;
— the use of the specific terminology of this International Standard within the organization.
The quality management system requirements specified in this International Standard are complemen-
tary to requirements for products and services.
viii
ISO 22163:2023(E)
This International Standard employs the process approach, which incorporates the Plan-Do-Check-Act
(PDCA) cycle and risk-based thinking.
The process approach enables an organization to plan its processes and their interactions.
The PDCA cycle enables an organization to ensure that its processes are adequately resourced and
managed, and that opportunities for improvement are determined and acted on.
Risk-based thinking enables an organization to determine the factors that could cause its processes and
its quality management system to deviate from the planned results, to put in place preventive controls
to minimize negative effects and to make maximum use of opportunities as they arise.
Consistently meeting requirements and addressing future needs and expectations poses a challenge
for organizations in an increasingly dynamic and complex environment. To achieve this objective, the
organization might find it necessary to adopt various forms of improvement in addition to correction
and continual improvement, such as breakthrough change, innovation and re-organization.
In this International Standard, the following verbal forms are used:
— “shall” indicates a requirement;
— “should” indicates a recommendation;
— “may” indicates a permission;
— “can” indicates a possibility or a capability.
Information marked as “NOTE” is for guidance in understanding or clarifying the associated requirement.
0.2  Quality management principles
ISO 9001:2015, Quality management systems — Requirements
0.2  Quality management principles
This International Standard is based on the quality management principles described in ISO 9000. The
descriptions include a statement of each principle, a rationale of why the principle is important for the
organization, some examples of benefits associated with the principle and examples of typical actions
to improve the organization's performance when applying the principle.
The quality management principles are:
— customer focus;
— leadership;
— engagement of people;
— process approach;
— improvement;
— evidence-based decision making;
— relationship management.
0.3  Process approach
0.3.1  General
ISO 9001:2015, Quality management systems — Requirements
0.3  Process approach
0.3.1  General
This International Standard promotes the adoption of a process approach when developing, implement-
ing and improving the effectiveness of a quality management system, to enhance customer satisfaction
by meeting customer requirements. Specific requirements considered essential to the adoption of a
process approach are included in 4.4.
ix
ISO 22163:2023(E)
Understanding and managing interrelated processes as a system contributes to the organization's
effectiveness and efficiency in achieving its intended results. This approach enables the organization
to control the interrelationships and interdependencies among the processes of the system, so that the
overall performance of the organization can be enhanced.
The process approach involves the systematic definition and management of processes, and their
interactions, so as to achieve the intended results in accordance with the quality policy and strategic
direction of the organization. Management of the processes and the system as a whole can be achieved
using the PDCA cycle (see 0.3.2) with an overall focus on risk-based thinking (see 0.3.3) aimed at taking
advantage of opportunities and preventing undesirable results.
The application of the process approach in a quality management system enables:
a) understanding and consistency in meeting requirements;
b) the consideration of processes in terms of added value;
c) the achievement of effective process performance;
d) improvement of processes based on evaluation of data and information.
Figure 1 gives a schematic representation of any process and shows the interaction of its elements. The
monitoring and measuring check points, which are necessary for control, are specific to each process
and will vary depending on the related risks.

0.3.2  Plan-Do-Check-Act cycle
ISO 9001:2015, Quality management systems — Requirements
0.3.2  Plan-Do-Check-Act cycle
The PDCA cycle can be applied to all processes and to the quality management system as a whole. Fig-
ure 2 illustrates how Clauses 4 to 10 can be grouped in relation to the PDCA cycle.
x
ISO 22163:2023(E)
NOTE Numbers in brackets refer to the clauses in this International Standard.
Figure 2 — Representation of the structure of this International Standard in the PDCA cycle
The PDCA cycle can be briefly described as follows:
— Plan: establish the objectives of the system and its processes, and the resources needed to deliver
results in accordance with customers' requirements and the organization's policies, and identify
and address risks and opportunities;
— Do: implement what was planned;
— Check: monitor and (where applicable) measure processes and the resulting products and services
against policies, objectives, requirements and planned activities, and report the results;
— Act: take actions to improve performance, as necessary.
0.3.3  Risk-based thinking
ISO 9001:2015, Quality management systems — Requirements
0.3.3  Risk-based thinking
Risk-based thinking is essential for achieving an effective quality management system. The concept of
risk-based thinking has been implicit in previous editions of this International Standard including, for
example, carrying out preventive action to eliminate potential nonconformities, analysing any noncon-
formities that do occur, and taking action to prevent recurrence that is appropriate for the effects of
the nonconformity.
To conform to the requirements of this International Standard, an organization needs to plan and imple-
ment actions to address risks and opportunities. Addressing both risks and opportunities establishes
a basis for increasing the effectiveness of the quality management system, achieving improved results
and preventing negative effects.
xi

Opportunities can arise as a result of a situation favourable to achieving an intended result, for ex-
ample, a set of circumstances that allow the organization to attract customers, develop new products
and services, reduce waste or improve productivity. Actions to address opportunities can also include
consideration of associated risks. Risk is the effect of uncertainty and any such uncertainty can have
positive or negative effects. A positive deviation arising from a risk can provide an opportunity, but not
all positive effects of risk result in opportunities.

0.4  Relationship with other management system standards
This International Standard applies the framework developed by ISO to improve alignment among its
International Standards for management systems.
This International Standard enables an organization to use the process approach, coupled with the PDCA
cycle and risk-based thinking, to align or integrate its quality management system with the requirements
of other management system standards.
This International Standard relates to ISO 9000 and ISO 9004 as follows:
— ISO 9000 Quality management systems — Fundamentals and vocabulary provides essential
background for the proper understanding and implementation of this International Standard;
— ISO 9004 Managing for the sustained success of an organization — A quality management approach
provides guidance for organizations that choose to progress beyond the requirements of this
International Standard.
This International Standard does not include requirements specific to other management systems,
such as those for environmental management, occupational health and safety management, or financial
management.
Sector-specific quality management system standards based on the requirements of this International
Standard have been developed for a number of sectors. Some of these standards specify additional quality
management system requirements, while others are limited to providing guidance to the application of
this International Standard within the particular sector.
A matrix showing the correlation between the clauses of this edition of this International Standard
and the previous edition (ISO 9001:2008) can be found on the ISO/TC 176/SC 2 open access website at:
