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;
---------------------- Page: 8 ----------------------
SIST EN 15341:2019
EN 15341:2019 (E)
— 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 the support of ICT and Enabling

Technologies (e.g. Industry 4.0).

The size and the depth of utilization depends on the maturity degree of each maintenance department

and from its commitment to develop Maintenance activities towards the excellence.

During the life of each physical asset and its components, it is necessary to carry out maintenance

activities to repair the failures, contain the degradation and wear with appropriate preventive actions, so

as to lengthen the life of the unit and meet the required level of performance.

The Maintenance Function is an integration of 6 Sub-functions with the addition of methodology of

Physical Asset Management and hardware and software of the Information and Communication

Technology (see Figure 1).
Figure 1 — Maintenance function and core framework
---------------------- Page: 9 ----------------------
SIST EN 15341:2019
EN 15341:2019 (E)

In this integrated maintenance system each sub function shall be developed in order to achieve the

objectives assigned to the Maintenance Function. These objectives can include e.g. H.S.E. issues, integrity

and competitiveness of the physical assets, balancing productivity, costs and service.

In order to cover all the major aspects of physical assets management the key performance indicators are

structured into eight groups, one for physical asset management, six dedicated to maintenance sub-

functions, and the last one for the information communication technologies.
5 KPIs and their objectives
5.1 General

When the actual or expected performance is not satisfactory, management shall define objectives and

strategies to improve the resources utilization of involved sub-functions using the KPIs, allowing the

organization to:
a) define the objectives;
b) measure the performance;
c) compare the performance versus the historical value of benchmarks;
d) identify strengths and weaknesses;
e) control progress and changes;
f) define plan and strategies of improvements;
g) make regular measurement of changes over time;
h) share the results.
These indicators can be used:

• on a periodic basis, for instance by preparing and following-up a budget, during performance

assessment, comparing results in many ways: budgeted, expected, predicted, planned, actual, etc.;

• on a spot basis, for instance within the framework of specific audits, studies and/or benchmarking.

The period of time to be considered for measurement depends on the organization policy, aims and time

constants of measured phenomena; it can be: day, week, month, quarter, semester, year, etc.

The KPIs can be often calculated as a ratio between factors (numerator and denominator) measuring the

activities, resources or events, according to a given formula, but can also be the result of the quantitative

or qualitative questionnaire.

The numerical values, the qualitative and the quantitative data to calculate each KPI shall be collected

and elaborated based on available methods and procedures of general industrial accounting and specific

management accounting rules, applied to the maintenance function.

These indicators are used to measure any qualitative or quantitative characteristics of an item or a

process to create a homogeneous base to compare and set objectives to improve.

In some cases it is suitable to use specific pre-prepared questionnaire to give to the managers and experts

the possibility to carry out qualitative assessments in a simple and efficient way.

---------------------- Page: 10 ----------------------
SIST EN 15341:2019
EN 15341:2019 (E)
5.2 Influencing factors

The Influencing factors are variable conditions outside of Maintenance Function which have an impact

on the measured indicator. They can be general or specific, internal or external, controllable or non-

controllable.
Examples of external influencing factors are:
a) location,
b) society culture,
c) national labour policies and costs,
d) market and economy,
e) laws and regulations,
f) sector / branches,
g) stakeholders,
h) technology,
i) environmental conditions.
Examples of internal Influencing factors are:
j) organization culture,
k) organization scale,
l) organization objectives,
m) criticality of the physical asset,
n) severity and complexity of the process,
o) product mix,
p) physical assets scale and complexity,
q) utilization rate,
r) age of physical asset.

These factors shall be considered as reference conditions to understand the framework where

maintenance is operating. It is necessary to consider the influence and the impact of factors, in order to

achieve homogeneous and appropriate evaluations without misunderstandings and misleading.

5.3 Maintenance Resources
The maintenance resources are:
— competence of direct and indirect people;
— labour internal and external;
---------------------- Page: 11 ----------------------
SIST EN 15341:2019
EN 15341:2019 (E)
— spare parts and materials;
— diagnostics and predictive technologies;
— maintenance tools and equipments;
— engineering knowledge;
— good maintenance practices to repair, restore, prevent and improve;

— information technology systems: hardware and software and enabling technologies (e.g Industry

4.0);
— supply and supporting services.

The role of management is to achieve the best maintenance performance, in line with the stated company

objectives, using and dosing the appropriate resources, optimizing all the management, organizational

and administrative aspects with an integrated information system.
5.4 Maintenance Processes

The maintenance processes are the various actions used by each sub-function to implement the activities

to achieve the best competitiveness and suitable results according to the stated aim of the organization,

see EN 17007.
6 Maintenance KPIs Matrix

Table 1 shows the KPIs of Maintenance within a Physical Asset Management, the 6 maintenance Sub-

functions and the Information Communication Technology.

The KPIs reported in the matrix related to each subsystems/methodology are divided in areas, which

represent the fundamental contents or characteristic to be measured, controlled and improved to achieve

a quantitatively and qualitatively excellent assessment.

Most indicators can be used at different aggregation levels depending on whether they are used to

measure the performance of physical assets, production lines, given equipment, item, etc.

The indicators can be split by professional levels in relation to the organizational structure established

by each organization.

7 KPIs of “Maintenance within Physical Asset Management”

Maintenance within physical asset management allows the optimal life cycle management of physical

assets to sustainably achieve the stated organization objectives.

The Maintenance activities play a significant role in the life cycle management of physical assets, because

the maintenance function takes care of their integrity for the majority of the life.

Physical asset management indicates the appropriate importance of maintenance in the various life cycle

stages and helps the maintenance management to define effective long term maintenance strategy.

The physical assets management provides the interrelations between the maintenance and the other

physical asset processes, in order to measure the performances through the whole asset life, in line with

vision, mission, values and organization objectives.
