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 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
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.
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;
— 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.
The main KPIs, named PHA , shared by driven areas as reported in Table 2 are the following:
i
— Sustainability: PHA1, PHA2, PHA3;
— Capacity, Effectiveness, Integrity: PHA4, PHA5, PHA6, PHA7, PHA8, PHA9, PHA10, PHA11;

8 KPIs of Sub-function “Health-Safety-Environment (HSE)” on Maintenance
This sub-function concerns the implementation of policies, procedures by the maintenance management
using adequate resources to prevent injuries and losses and be compliant with laws, rules and company
objectives.
The H.S.E. laws, rules and procedures are fundamental requirements for Maintenance to carry out Risk
Analysis and to do preventive actions, keeping the integrity of each equipment in the condition that
enable them to run (operate) in a sustainable way according to requirements of law and standards.
The whole can be considered a subsystem that involves so much maintenance because is widely
recognized prone to accidents in any field of activities.
It means that the Operational Availability of the Physical Asset includes conformity to HSE requirements
to prevent any unacceptable risk and unassessed danger to people and environment.
The Failure and Injury Risk Analysis is a Tool to be used as preventive action in each corrective, proactive,
predictive, on condition, preventive maintenance work or technical improvement.
The Main Contents and knowledge to be complied are:
— Laws, Policy and Strategy on HSE,
— HSE Responsibility, Objectives and Plans,
2)
— HSE Risk Analysis and RAMS evaluations,
— HSE Procedure and Device to Prevent Accidents,
— Risk Analysis and Hazard Assessment,
— HSE Records and related Indicator,
— Failure Mode, Effects and criticality analysis,
— Good practices in health- safety- environment,
— Protective Equipment (collective and personal),
— Safety manual and Handbook,
— Emergency Plan,
— Accident report and Investigation report,
— Occupational Diseases and Accidents,
— Safety Education and Training.
It includes the HSE performance and competence of maintenance personnel, internal or external both
insourced and outsourced, in order to meet the requirements of influencing factors (see 5.2).
The 4 main driven areas of HSE, related to the Maintenance performances and the KPIs, named HSE1-22,
are:
— Conformity to Laws and Rules: HSE1, HSE2, HSE3,

9 KPIs of Sub-function “Maintenance Management”
Maintenance Management is a combination of the resources, disciplines, knowledge, competences and
tools to define a medium term plan in line with the industrial company plan. It is the coordination and
control of activities implemented on physical assets to achieve the established objectives in the existing
framework and constraints.
The Maintenance Management applies theories, applications and practices of management, available
internal and external resources to coordinate the activities of the maintenance in order to achieve the
best suitable maintenance performances. The physical assets are utilized in the existing framework,
according to the vision, mission, values, policies and stated objectives of the organization.
The Maintenance Management has:
— to comply with the laws, HSE, rules and company procedure;
— to define the maintenance strategy and implement it, see ISO 55001;
— to manage the Maintenance Function and the related sub-functions;
— to optimize people competence, productivity of maintenance resources, effectiveness and efficiency
of the processes;
— to improve the technical standard;
— to achieve the ”best added value” for plants, facilities and infrastructures in the optimal life cycle,
established by industrial strategies and physical asset management;
— to consider the external and internal influencing factors that are fundamental to understand the
status of the organization /site /plant and his evolution towards the excellent organizational models.
The main driven areas and related KPIs, named M, are the following:
— Maintenance Strategy: M1, M2, M3;
— Management of Function: M4, M5, M6, M7, M8, M9, M10, M11, M12, M13;
— Technical Assessment: M11, M12, M13, M14, M15, M16, M17, M18, M19;
— Continuous Improvement: M20, M21, M22.
The indicators M1, M2, M3, M4, M5, M6, M7, M8, M9 are qualitative, not defined by a formula.
In order to get a qualitative value it is recommended to use an “Evaluation Questionnaire” to appraise the
specific degree of the subject in each specific reality for each indicator.
In this way it will be possible to assess the position of maintenance function in the framework of
maintenance maturity model and estimate the level with votes of merit.

Opomba 2: Vsebuje vnaprej določen niz aktivnosti z določenimi materiali, rezervnimi deli, orodjem in delovno silo, potrebnimi
za dokončanje dela.
4 Funkcija vzdrževanja
Funkcija vzdrževanja se izvaja v različnih industrijskih obratih, objektih, infrastrukturah, deluje v različnih
okvirih in pomenih v različnem obsegu, z različnimi strukturami, cilji, posebnimi omejitvami in vplivnimi
dejavniki (glej 5.2 in 5.3).
V tem pomenu je primerno opredeliti organizacijski model funkcije vzdrževanja kot standardno
izhodišče, ki ga je treba uporabiti glede na zahtevane cilje, razpoložljive vire in obstoječe omejitve.
Ta model funkcije vzdrževanja je predstavljen na sliki 1.
Model upošteva, da mora funkcija vzdrževanja doseči zastavljene cilje in odličnost, uporabiti ustrezno
kombinacijo ali dele različnih disciplin, kot so HSE (zdravje, varnost, okolje), uprava, IKT (informacijska
in komunikacijska tehnologija) itd.
Naloga vodenja/upravljanja je:
a) uporabiti ustrezne vire, znanje, pravila, postopke,
b) izbrati, kako mora vzdrževanje graditi in organizirati različne zadeve in discipline v naslednjih
podfunkcijah/podpodročjih:
̶ HSE pri vzdrževanju,
̶ vodenje/upravljanje vzdrževanja,
̶ kompetentnost vzdrževalcev,
̶ vzdrževalni inženiring,
̶ organizacija in podpora vzdrževanju,
̶ uprava in oskrba.

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.
SIST EN 15341:2019+A1 : 2022
Fizično premoženje se vzdržuje tako, da se lahko opravljajo zahtevane funkcije, zato mora vodstvo
delovati v osnovnem okviru, ki vključuje:
̶ podjetje,
̶ razpoložljive vire,
̶ uporabo IKT in omogočitvenih/prebojnih tehnologij (npr. industrija 4.0).
Ta dokument ob priznavanju hitrega razvoja vzdrževanja, tako z organizacijske kot s tehnološke strani,
zagotavlja pregled vsebine podfunkcij, aktivnosti in orodij, ki jih je treba upoštevati pri opredelitvi
aktivnosti in kazalnikov za doseganje ciljev.
Za doseganje ciljev vzdrževanja fizičnega premoženja je primerno uporabiti vse discipline funkcije
vzdrževanja v integriranem okviru skupaj s podporo IKT in omogočitvenih tehnologij (npr. industrija 4.0).
Obseg in intenzivnost uporabe sta odvisna od stopnje zrelosti vsakega oddelka vzdrževanja in od
njegove zavezanosti razvoju vzdrževanja v smeri odličnosti.
Med življenjsko dobo vsakega fizičnega premoženja in njegovih komponent je treba izvajati vzdrževalne
aktivnosti za odpravljanje odpovedi, omejiti poslabšanje in obrabo z ustreznimi preventivnimi ukrepi, da
se ohranja življenjska doba enote in doseže zahtevana raven tehničnih lastnosti.
Funkcija vzdrževanja je integracija šestih podfunkcij, ki jih nadgrajuje metodologija vodenja/upravljanja
fizičnega premoženja ter strojne in programske opreme informacijske in komunikacijske tehnologije (glej
sliko 1).

SIST EN 15341:2019+A1 : 2022
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).

SIST EN 15341:2019+A1 : 2022
V tem integriranem sistemu vzdrževanja je treba razviti vsako podfunkcijo za doseganje ciljev, ki jih ima
funkcija vzdrževanja. Ti cilji lahko vključujejo npr. vprašanja HSE, celovitost in konkurenčnost fizičnega
premoženja, uravnoteženje produktivnosti, stroškov in storitev.
Da bi bili zajeti vsi glavni vidiki vodenja/upravljanja fizičnega premoženja, so ključni kazalniki uspešnosti
strukturirani v osem skupin, eno za vodenje/upravljanje fizičnega premoženja, šest za vzdrževalne
podfunkcije in zadnjo za informacijsko-komunikacijske tehnologije.
5 KPI in njihovi cilji
5.1 Splošno
Kadar dejanska ali pričakovana uspešnost ni zadovoljiva, mora vodstvo opredeliti cilje in strategije za
izboljšanje izkoriščenosti vključenih podfunkcij s pomočjo ključnih kazalnikov uspešnosti, kar
organizaciji omogoča:
a) opredeliti cilje,
b) meriti uspešnost,
c) primerjati uspešnost s preteklimi referenčnimi vrednostmi,
d) prepoznati prednosti in slabosti,
e) nadzirati napredek in spremembe,
f) opredeliti plane/načrte in strategije izboljšav,
g) redno meriti spremembe v času,
h) obveščati o rezultatih.
Ti kazalniki se lahko uporabijo:
̶ občasno, na primer s pripravo in spremljanjem proračuna med ocenjevanjem uspešnosti, pri čemer
se rezultati primerjajo na več načinov: kot proračunski, pričakovani, predvideni,
planirani/načrtovani, dejanski itd.,
̶ na kraju samem, na primer v okviru posebnih revizij, študij in/ali primerjalnih analiz.
Časovno obdobje, ki se upošteva za merjenje, je odvisno od organizacijske politike, ciljev in časovnih
konstant merjenih pojavov in je lahko dan, teden, mesec, četrtletje, polletje, leto itd.
KPI se lahko pogosto izračunajo kot razmerje med dejavniki (števcem in imenovalcem) pri merjenju
aktivnosti, virov ali dogodkov v skladu z dano formulo, lahko pa so tudi rezultat kvantitativnega ali
kvalitativnega vprašalnika.
Številčne vrednosti ter kvalitativne in kvantitativne podatke za izračun vsakega KPI je treba zbrati in
izdelati na podlagi razpoložljivih metod in postopkov splošnega industrijskega računovodstva in
posebnih pravil vodstvenega računovodstva, ki se uporabljajo za funkcijo vzdrževanja.
Ti kazalniki se uporabljajo za merjenje vsakršnih kvalitativnih ali kvantitativnih značilnosti
predmeta/elementa ali procesa za ustvarjanje homogene osnove za primerjavo in določitev ciljev za
izboljšanje.
V nekaterih primerih je ustrezneje uporabiti poseben vnaprej pripravljen vprašalnik, da lahko vodje in
strokovnjaki na preprost in učinkovit način opravijo kvalitativne ocene.
SIST EN 15341:2019+A1 : 2022
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
subfunctions, 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.
SIST EN 15341:2019+A1 : 2022
5.2 Vplivni dejavniki
Vplivni dejavniki so spremenljivi pogoji zunaj funkcije vzdrževanja, ki vplivajo na spremljani kazalnik.
Lahko so splošni ali posebni, notranji ali zunanji, obvladljivi ali neobvladljivi.
Primeri zunanjih vplivnih dejavnikov so:
a) lokacija,
b) družbeno okolje,
c) nacionalne politike dela in stroški,
d) trg in gospodarstvo,
e) zakoni in predpisi,
f) področje/panoge,

SIST EN 15341:2019+A1 : 2022
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:

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;
– spare parts and materials;
– diagnostics and predictive technologies;
– maintenance tools and equipments;
– engineering knowledge;

Preglednica 1 prikazuje kazalnike KPI vzdrževanja v okviru vodenja/upravljanja fizičnega premoženja,
šestih podfunkcij vzdrževanja in informacijsko-komunikacijske tehnologije.
Ključni kazalniki uspešnosti, navedeni v matriki, povezani z vsakim podsistemom/metodologijo, so
razdeljeni na področja, ki predstavljajo temeljne vsebine ali značilnosti, ki jih je treba meriti, nadzorovati
in izboljšati, da se doseže kvantitativno in kvalitativno odlična ocena.
Večino kazalnikov je mogoče uporabiti na različnih stopnjah združevanja odvisno od tega, ali se
uporabljajo za merjenje uspešnosti fizičnega premoženja, proizvodnih linij, dane opreme,
predmeta/elementa idr.
Kazalniki se lahko razdelijo po poklicnih ravneh glede na organizacijsko strukturo, ki jo vzpostavi vsaka
organizacija.
SIST EN 15341:2019+A1 : 2022
– 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
Subfunctions and the Information Communication Technology.
