Maintenance process and associated indicators

Maintenance is a process since it consists of organised, coordinated tasks using resources and performed by various players to obtain a given result. This proposal consists in providing a generic description of the maintenance process to allow an understanding of the actions and interactions between processes. It should apply to all systems and all organisations and should therefore be established without a particular organisation in mind and does not aim to propose one.
The purpose of the breakdown into processes and the representation of their interrelationships is to help maintenance personnel, and particularly management, to:
 clearly identify the actions to be taken in order to meet the overall objectives set by Management in terms of maintenance. It provides a breakdown of the maintenance process into several levels, which makes it possible to clearly indicate the activities to be carried out at a relevant level of detail;
 delegate responsibilities that ensure the realisation of the identified actions with the required performance levels;
 for each process, clearly determine:
 the necessary inputs and their origin;
 the required results and their intended uses; and, in that way, define all the links that join the processes together and allow the realisation of the overall process;
 provide the ability to define indicators and scorecards in relation with EN15341 for measuring the realisation of each process and monitoring its effectiveness.
This description of the maintenance process will help maintenance managers by giving them a way to compare their organisation to the generic representation described and to detect insufficient actions, unassigned responsibilities and/or poorly established links.

Instandhaltungsprozess

Diese Europäische Norm enthält eine allgemeine Beschreibung des Instandhaltungsprozesses. In ihr werden die Eigenschaften der gesamten Prozesse und Teile des Instandhaltungsprozesses festgelegt und ein Instandhaltungsmodell erstellt, um Richtlinien zur Definition von Leistungskennzahlen bereitzustellen.
Diese Europäische Norm ist auf alle Organisationen (Unternehmen Institutionen, Agenturen usw.) anwendbar, die für die Instandhaltung physischer Anlagen verantwortlich sind. Sie wurde daher nicht im Hinblick auf eine bestimmte Organisation erstellt und zielt auch nicht darauf ab, eine solche vorzuschlagen. Diese Beschreibung kann je nach Art und Größe der Organisation, die für die Instandhaltung gewählt wurde, der Komplexität der instandgehaltenen Systeme und dem Ausmaß von extern vergebenen Dienstleistungen angepasst werden.
Der Zweck der Aufteilung in Prozesse und der Darstellung ihrer Zusammenhänge ) ist, dem Instandhaltungspersonal und vor allem dem Management auf verschiedenen Ebenen dabei zu helfen:
-   die notwendigen Aktionen oder Maßnahmen klar zu identifizieren, um die Gesamtziele, die vom Management in Bezug auf die Instandhaltung definiert wurden, zu erreichen;
-   Verantwortlichkeiten zu delegieren, um die Umsetzung der Aktionen und Maßnahmen auf den notwendigen Leistungsstufen sicherzustellen;
-   für jeden Prozess Folgendes klar zu bestimmen:
a)   die notwendigen Eingaben und deren Ursprung;
b)   die erforderlichen Ergebnisse und die geplanten Anwendungen;
-   die Leistungsfähigkeit zu überwachen und quantitativ auf verschiedenen Ebenen der Aufteilung in Prozesse zu bewerten;
-   die Sammlung und Verteilung von Daten zu verbessern.
Diese Norm umfasst keine Softwareinstandhaltungen, ist aber auf Objekte anwendbar, welche Software umfassen.

Processus de maintenance et indicateurs associés

La présente Norme européenne donne une description générique du processus maintenance. Elle définit les caractéristiques de tous les processus faisant partie du processus maintenance et établit un modèle de maintenance donnant des lignes directrices pour la définition des indicateurs.
La présente Norme européenne s’applique à toutes les organisations (entreprise, institution, agence, etc.) chargées de la maintenance des actifs physiques. Elle a donc été établie sans présupposer d’organisation particulière et n’a pas pour objectif d’en proposer. Cette description peut être adaptée en fonction du type et de la taille d’organisation choisie pour effectuer la maintenance, de la complexité des systèmes maintenus et de l’étendue des prestations externes.
Le découpage en processus et la représentation de leurs interrelations ) ont pour objectif d’aider le personnel de maintenance, et notamment le management à différents niveaux, à :
-   identifier clairement les actions à mener pour satisfaire les objectifs globaux fixés par la Direction pour la maintenance ;
-   déléguer les responsabilités qui garantissent la réalisation des actions avec les niveaux de performance exigés ;
-   déterminer clairement pour chaque processus :
a)   les entrées nécessaires et leur provenance ;
b)   les résultats exigés et leurs destinations ;
-   suivre et évaluer quantitativement les performances obtenues à différents niveaux de la décomposition en processus ;
-   améliorer le recueil et la diffusion des données.
La présente norme ne couvre pas la maintenance des logiciels pris isolément, mais s’applique aux biens contenant des logiciels.

Proces vzdrzevanja in z njim povezani kazalniki

Vzdrževanje je postopek, ker je sestavljeno iz organiziranih, usklajenih opravil z uporabo virov in ga za pridobitev rezultata izvaja več akterjev. Ta predlog ponuja splošen opis postopka vzdrževanja, ki omogoča razumevanje dejanj in interakcij med postopki. Veljati bi moral za vse sisteme in organizacije, zato mora biti sestavljen brez osredotočanja na določeno organizacijo ali predlaganja take organizacije. Namen razčlenitve v postopke in predstavitev njihovih medsebojnih razmerij je pomagati vzdrževalnemu osebju in še zlasti vodstvu: jasno opredeliti ukrepe, ki jih je treba sprejeti za izpolnitev splošnih ciljev, ki jih je za vzdrževanje določilo vodstvo. Zagotavlja razčlenitev postopka vzdrževanja na več ravni, kar omogoča jasen prikaz dejavnosti, ki jih je treba opraviti na ustrezni ravni podrobnosti:  dodeliti odgovornosti, ki zagotavljajo uresničitev opredeljenih ukrepov z zahtevano stopnjo učinkovitosti;  za vsak postopek jasno določiti:  potrebne surovine in njihov izvor;  potrebne rezultate in njihovo predvideno uporabo; in na ta način določiti vse povezave, ki združujejo procese in omogočajo uresničitev celotnega postopka;  omogočiti določanje kazalnikov in sistemov kazalnikov v zvezi s standardom EN 15341 za merjenje uresničevanja vsakega postopka in spremljanje njegove učinkovitosti. Ta opis postopka vzdrževanja bo upravniku ponudil način za primerjavo organizacije z opisano generično predstavitvijo in odkrivanje nezadostnih ukrepov, nedodeljenih odgovornosti in/ali slabo vzpostavljenih povezav.

EN 17007:2017 (E) 3 European foreword This document (EN 17007:2017) has been prepared by Technical Committee CEN/TC 319 “Maintenance”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2018 and conflicting national standards shall be withdrawn at the latest by April 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 17007:2018

EN 17007:2017 (E) 4 Introduction According to EN ISO 9001, maintenance is a process since it consists of organized, coordinated tasks using resources and performed by various stakeholders to obtain a given result. Terminology standard EN 13306 defines it as the “combination of all technical, administrative and managerial actions during the life cycle of an item intended to retain it in, or restore it to, a state in which it can perform the required function.” It seemed appropriate to formalize the maintenance process through a breakdown into processes that provides the following advantages: — it makes it possible to clearly indicate the activities to be carried out with a relevant level of detail; — it indicates the inputs/outputs of each sub-process and defines all the links that join them together and allow the realization of the overall process; — it provides the ability to define indicators for measuring the realization of each process and monitoring its effectiveness. The aim of this document is to allow an understanding of the actions and interactions between maintenance processes. It provides maintenance managers with a management tool by giving them a way to compare their organization to the generic representation described and to detect insufficient actions, unassigned responsibilities and/or poorly established links. It gives information to define indicators, dedicated to specific processes, allowing the creation of scorecards that are appropriate for monitoring activities and measuring performance. SIST EN 17007:2018

EN 17007:2017 (E) 5 1 Scope This European Standard provides a generic description of the maintenance process. It specifies the characteristics of all the processes, parts of maintenance process, and establishes a maintenance model to gives guidelines for defining indicators. This European Standard is applicable to all organizations (company, institution, agency, etc.) in charge of maintaining physical assets. Therefore, it has been established without a particular organization in mind and does not aim to propose one. This description could be adapted based on the type and size of organization chosen to perform the maintenance, the complexity of the systems maintained and the scope of the external contracted services. The purpose of the breakdown into processes and the representation of their inter-relationships1) is to help maintenance personnel, and particularly management at different levels, to: — clearly identify the actions to be taken in order to meet the overall objectives set by Management in terms of maintenance; — delegate responsibilities that ensure the realization of the actions with the required performance levels; — for each process, clearly determine: a) the necessary inputs and their origin; b) the required results and their intended uses; — monitor and quantitatively assess the performance obtained at various levels of the breakdown into processes; — improve the collection and the distribution of data. This standard does not cover software maintenance itself, but applies to items containing software. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

sequence flows between processes, defines execution order of activities 5 Principles of maintenance process breakdown 5.1 Process families To more easily identify processes, it is helpful to classify them into three main families a) Management process This includes determining the objectives and the policy to be implemented in order to achieve them, deploying the company's means and allocating the resources. It ensures the coherence of the realization and support processes. It includes measuring and monitoring the process system and using the results to improve performance. b) Realization processes These contribute directly to achieving the expected result and are designed to ensure that the needs expressed by the customer are satisfied. They encompass all activities related to the realization cycle of the product or service. SIST EN 17007:2018

EN 17007:2017 (E) 10 c) Support processes These are essential to the functioning of the other processes (realization processes, other support processes, management process) as they provide them with the necessary resources. They include activities related to: — human resources; — financial resources; — material resources and their maintenance (premises, equipment, software, etc.); — information processing. 5.2 Breakdown into levels Level 1 of the breakdown is an overall mapping that identifies the processes and classifies them into each of the families based on the diagram shown in Figure 1.

Figure 1 — Level 1 of the process mapping Each level 1 process is in turn broken down into level 2 processes. In addition to the component processes, this level shows the input and output data of each process as well as its origins and destinations. This provides a sequenced representation of the level 2 processes that contribute to the realization of the level 1 process (see Figure 2). SIST EN 17007:2018

EN 17007:2017 (E) 11

Figure 2 — Level 2 of the process mapping — Example Some input data are output data from processes outside the process broken down or is supplied by entities outside the maintenance process. The same may be true for output destinations. These external origins and destinations are indicated on the diagram. A third level may be described, where necessary, to further clarify the actions, but this level is not discussed in this standard. A profile is drawn up for each level 2 process. It includes: — the name of the process; — the purpose(s) of the process, which is expressed in terms of action(s) with clearly stated goals; — the activities that comprise the process. These activities constitute level 3 of the breakdown, which is not shown in the form of a diagram in this document; — the input data and products which are needed to realize the process. They come from either other level 2 processes, other level 1 processes or entities outside the maintenance process; — the output data and products which are created or modified by the process and are intended for either other level 2 processes, other level 1 processes or entities outside the maintenance process; SIST EN 17007:2018

EN 17007:2017 (E) 12 — regardless of the level of the process, the stakeholders are: the person who requested the process, the process manager, the customer, the beneficiary of the process and input data suppliers. These stakeholders are relative to the company's organization and can therefore not be generic. As a result, information about them is not provided in this standard and it is up to each company to do so. This makes it possible to clearly identify the stakeholders' responsibilities, detect any insufficiencies and assign tasks to each stakeholder, identify customers, objectives and suppliers; — the interfaces with the other processes summarize all the related processes. These can be data or product suppliers or customers of the output data or products; — the constraints related to realization of the process are a way to specify certain requirements or situations. They shall be taken into account by the process; — Elements to define indicators related to the process. Each company shall define its own indicators, first to assess the effectiveness of its processes and attainment of the targets assigned to them, and secondly to monitor the realization of the actions taken to ensure their progress and adherence to timeframes. The proposed elements serve to define relevant indicators. 5.3 Use of the Maintenance process breakdown The representation of the maintenance process, established according to the aforementioned principles, is provided in Clause 5. It is generic, which means that it is not based on any particular organization and draws on best practices generally implemented in the maintenance sector. It is then up to each company to use this breakdown to build or update its organization. This can be achieved by identifying, within its own organization, the structural entities that realize the various processes defined. It is then necessary to ensure that: — each process exists and is managed; — each process is unique; — the inputs/outputs are clearly defined (products, data, timeframes, etc.); — the suppliers and customers of the inputs/outputs are clearly designated by name; — the responsible persons for the processes (process owners) has been defined; — the indicators are regularly analysed and published in order to monitor the progress of the actions and measure the effectiveness of the processes and their ability to achieve the assigned objectives. This task offers many advantages: — the result obtained provides a basis for understanding how the company's maintenance process is performed and improves the confidence of the customer into the ability of the maintenance provider; — each entity of the organization clearly sees its position in relation to the others and the importance of its actions within the maintenance process. Each person's work is more easily recognized thanks to a greater ability to communicate the results obtained; — responsibilities are defined without overlaps or ambiguities and objectives are established and quantified; — the responsible persons have a better understanding of the objectives, which improves synergy and teamwork; SIST EN 17007:2018

EN 17007:2017 (E) 13 — management of the processes is significantly easier. Management shall have the means to detect malfunctions, measure non-conformities and any deviations from the objectives and take appropriate measures to correct or update the processes in question (e.g. it provides framework for assessment and benchmarking); — formalization of the processes is a tool for training the various job profiles and developing the company's knowledge and facilitates changes through a better understanding of their consequences; — formalizing the sequencing of actions and using indicators to detect deviations helps to ensure the continuous improvement of the maintenance process. — provides a framework for systematic Information System support. It should be noted that each company shall adapt the various processes according to its field of activity and economic, geographic, political, cultural and other contexts. 6 Breakdown of the maintenance process and process profiles 6.1 Maintenance process

Figure 3 — Maintenance process (level 1 of the mapping) SIST EN 17007:2018

EN 17007:2017 (E) 14 The maintenance process consists of the following processes: a) the management process: — MAN: Manage maintenance (strategy and improvement, human resources, continuous improvement, compliance, etc.); b) the realization processes: — PRV: Prevent undesirable events by avoiding failures and faults; — COR: Restore the items in required state; — ACT: implement preventive and/or corrective actions on the item. — IMP: Improve the items; c) the support processes: HSE: Ensure personal health and safety to individuals and preserve environment in maintenance; BUD: Budget maintenance of items; DOC: Deliver the operational documentation; DTA: Manage data; IST: Provide the needed infrastructures; MRQ: Deliver maintenance requirements during items design and modification; OPT: Improve the results; RES: Provide internal human resources; SER: Provide external maintenance services; SPP: Deliver spare parts; TOL: Deliver the tools, support equipment and information system. Each of these processes is broken down at level 2 in the following figures. Elements (variables, quantities, characteristics, etc.) to define indicators are provided for each process. Each organization can adapt them to its own requirements. SIST EN 17007:2018

EN 17007:2017 (E) 15 6.2 MAN process: Manage maintenance

See Figure 4. Purpose(s) of the Process The aim of this process is to manage maintenance in order to achieve the objectives set by the company's management. Key activities / elementary processes — MAN.1 – Establish the maintenance policy, strategy and development actions Based on the company's missions, values, regulations compliance and general objectives, the policy establishes the direction, which gives priority to: — safety of individuals and items, product quality, environmental protection; — availability and useful life of the items; — optimization of maintenance costs, etc. The maintenance strategy, which results from the maintenance policy, requires that choices be made for: — developing, adapting or implementing maintenance methods; — organizing the internal resources (maintenance teams, stocks of spare parts and consumables, documentation, tools, etc.); — insourcing and/or outsourcing and/or contracting some or all of the maintenance tasks; — studying the economic impact of item modifications or improvements. The development of maintenance processes according to the strategy and the process to determine and prioritize improvements are defined and decided. — MAN.2 – Identify the internal or external activities (carried out by the staff of the user company or participating companies) The maintenance policy and strategy make it possible to clearly identify the activities carried out internally and those assigned to participating companies. In connection to budgeting this identification leads to choosing between “making” and “buying” and specifying the required skills. — MAN.3 – Determine the organization, job profiles and responsibilities Based on the direction and choices expressed in the policy and strategy, an organization is set up to realize the maintenance processes. Tasks and job profiles are established as well as possible needs to update present skills. Responsibilities are defined and assigned to the company's personnel. SIST EN 17007:2018

EN 17007:2017 (E) 16 — MAN.4 – Prepare and negotiate the budgets Economic plans (Budgets) are approved and adjusted by Management based on the budgeting process (BUD). — MAN.5 – Oversee the actions All the actions included in the maintenance process are coor
