Introduction
Maintenance Key Performance Indicators (KPI) of the Maintenance Function apply to all the physical
assets either industrial, infrastructures or civil buildings or transportation systems, etc.
These indicators should be used to:
a) measure the status;
b) compare (internal and external benchmarks);
c) diagnose (analysis of strengths and weaknesses);
d) identify objectives and define targets to be reached;
e) plan improvement actions;
f) regular measurement of changes over time.
Maintenance of software alone is not covered in this document. However, maintenance of items and
systems containing software is considered.
1 Scope
This document lists Key Performance Indicators (KPIs) of the Maintenance Function and gives guidelines
to define a set of suitable indicators, to appraise and to improve effectiveness, efficiency and
sustainability in the maintenance of the existing physical assets either industrial, infrastructures,
facilities, civil buildings or transportation systems, etc. in the framework of the external and internal
influencing factors.

4 Maintenance function
The Maintenance Function is operating in various industrial plants, facilities, infrastructures, acting in
different frameworks and contexts with different sizes, structures, objectives, specific constraints and
influencing factors (see 5.2 and 5.3).
In this context, it is suitable to define an organizational Model of Maintenance Function, as standard
reference to be implemented in relation with required objectives, available resources, and existing
constraints.
This Model of Maintenance Function is reported in Figure 1.
The Model considers that for the Maintenance function to achieve the assigned objectives and excellence,
it shall use an appropriate combination or parts of the various disciplines as HSE (Health Safety
Environment), Administration, ICT (Information and Communication Technology), etc.
It is Management task:
a) to implement the appropriate resources, knowledge, rules, procedures activities;
b) to select how the maintenance needs to build and organize the various matters and disciplines in the
following Sub Functions/Areas:
— HSE on Maintenance;
— Maintenance Management;
— Maintenance People Competence;
— Maintenance Engineering;
— Organization and Support for Maintenance;
— Administration and Supply.
The maintenance function maintains the physical assets so that it can perform the required functions and
consequently, the management shall act in a core framework that involves:
— The company
— The available resources
— The application of ICT and Enabling Technologies (e.g. Industry 4.0)
Acknowledging the fast development within maintenance, both from organizational and technological
point, this document provides an overview of the content of sub-functions, activities, and tools to be
considered when establishing activities and indicators to reach the targets.
It is suitable to use all the disciplines of Maintenance Function in the integrated framework to achieve the
objectives assigned to the Maintenance of the Physical Assets with th
