1.31 Contract Manager
A role that is supporting in improving the financials and service quality of the contracted deliveries. This
includes validating change request consequences and collaborating with the customer on Tactical level.
Corrective maintenance can be either planned or unplanned, also known as deferred or immediate
corrective maintenance.
1.32 CR: see Change Request
1.33 Critical assets
Critical assets are defined as assets that sustain your water or wastewater systems performance.
Determining the criticality of assets is based on an asset having a high risk of failure, and, major
consequences if it does fail. Here are five questions that will help you determine the criticality of a unique
asset:
Five questions to help determine asset criticality
1. How old is the asset?
2. What is the asset’s condition?
3. What is the asset’s failure history or how is it likely to fail?
4. What are the consequences of the failure (environmental, social, etc.)?
5. How much would it cost to repair or replace the asset (including cost related to collateral
damage such as street repairs)?
Answers to these five questions will help you determine which assets are critical.
1.34 Critical Facilities
The requirement to defined as critical facilities (CF) is that an unavailability of function will have adverse
effect on revenues, corporate image, regulatory compliance, safety, or any other mission critical objective
as defined by the organization.
The CF can be a complete building or facility, e.g. a data center. It may also be a combination of technical
supply systems providing Mission Critical Functions (MCF) within a larger facility, such as a hospital,
office or power plant.
1.35 CUE
CUE (Carbon usage effectiveness) is a metric for measuring the carbon gas a site emits. The output is
measured in kilograms of carbon dioxide per kilowatt-hour. The perfect CUE score is 0.0, meaning that no
carbon use is associated with the site’s operations.
1.36 Customer
Owner and user of Equipment located at the site.

1.37 Customer representative
Customer representative is the interface for delivery of services to the customer on operational level.
1.38 Datacenter Infrastructure Management
This is a category of solutions that integrates information technology (IT) and facility management
disciplines to centralize monitoring, management and intelligent capacity planning specifically for critical
facilities’ mission critical systems. Full DCIM deployments will involve specialized software, hardware and
sensors based on protocols e.g. BACnet/IP and SNMP for data collection. This enables monitoring of
datacenter performance measurement metrics, including industry standard metrics like PUE.
1.39 DCIM: see Datacenter Infrastructure Management
1.40 Disaster Recovery Plan
The disaster recovery plan (DRP or DR Plan) is a documented, structured approach with instructions for
responding to incidents. This step-by-step plan consists of the precautions to minimize the effects of a
disaster so the organization can continue to operate or quickly resume mission-critical functions.
1.41 Downtime
Downtime is a measure of system failure, expressed as the percentage of time a service level has been
breached by being unavailable. Downtime is the opposite of uptime.
1.42 DR Plan: see Disaster Recovery Plan
1.43 DRP: see Disaster Recovery Plan
1.44 EDMS: see Electronic Document Management System
1.45 Electronic Document Management System
An Electronic Document Management System is a software that typically can scan, store, retrieve and tag
documents with keywords in order to support an organization.
This is not to be confused with CAFM or CMMS.
1.46 EN 15221
The collective of standards of EN 15221 refer to the facility management (Facility Management, FM)
focusing on the FM as a product and the budget of FM, with the aim of unifying the operation of business
with service processes.
1.47 EN 50600
The Series of Standards EN 50600 aim to meet the European requirements for data center facilities and
critical infrastructures, including design, construction, operations and maintenance with a strong focus on
lowering environmental impact.
1.48 End of Life
At time of purchase of a site system, the lifecycle management rely on the vendors’ specifications for End
of Life (EOL).

EOL indicates that the product is at the end of its useful life (from the vendor's point of view).
Nevertheless, these specifications are based on laboratory measurements and there can be a significant
deviation from the specification and operation in a real site.
Therefore, EOL should not be confused with a change-out forecast for these items.
1.49 EOL: see End of Life
1.50 EOP for Site Management
EOP means Emergency Operating Procedures for Site Management Function.
These procedures define how the site is controlled and operated during abnormal circumstances or
emergency situations. It is a set of information that describes the characteristics of a process in terms that
will enable its effective execution, control and improvement until it fulfils the criteria to return to normal
operating conditions.
The term EOP is used interchangeably with Emergency Process Description for in the market.
This should not be confused with MEST or MOP which regulates on-site work practices.
1.51 Equipment
Equipment is used by the customer of a site. The equipment is typically used for work activities performed
in the Primary Area, where its function relies on the site capacity and site performance.
This is not to be confused with Site Systems (see ref) that is part of the site functionality that enable the
intended use of customer equipment.
1.52 ERE
ERE (Energy Re-use Efficiency) is a metric for measuring the efficiency of a site in measuring the benefits
of reusing waste to energy. Saving energy means not just saving money; the reduction also can make a
significant contribution to a site owner’s sustainability strategy in the form of emissions reductions.
1.53 ITIL
ITIL, formerly an acronym for Information Technology Infrastructure Library, is a set of detailed practices
for IT service management (ITSM) that focuses on aligning IT services with the needs of business. Even if
ITIL underpins ISO/IEC 20000, the International Service Management Standard for IT service
management, there are some differences between the ISO 20000 standard and the ITIL framework.
1.54 Key Performance Indicator
A Key Performance Indicator (KPI) is a quantifiable measure used to evaluate the success of how well a
service meets the objectives for its performance.
1.55 KPI: see ITIL
ITIL, formerly an acronym for Information Technology Infrastructure Library, is a set of detailed practices
for IT service management (ITSM) that focuses on aligning IT services with the needs of business. Even if
ITIL underpins ISO/IEC 20000, the International Service Management Standard for IT service
management, there are some differences between the ISO 20000 standard and the ITIL framework.

1.56 Key Performance Indicator
1.57 Maintenance, Corrective
Maintenance carried out following detection of an anomaly and aimed at restoring normal operating
conditions.
1.58 Maintenance, Preventive
Maintenance carried out at predetermined intervals or according to prescribed criteria, aimed at reducing
the failure risk or performance degradation of the assets.
1.59 Maintenance, Condition-based
Maintenance is carried out by performing Technical Risk Reviews and asset condition tests to define the
appropriate planned preventive maintenance and change-out forecast of site supply systems.
1.60 Maintenance, Predictive
Continuous online monitoring of actual site supply system condition and automatic comparison with
average values and expected performance. Maintenance is carried out when failure probability indicators
are increasing.
1.61 MCF: see Mission Critical Functions
1.62 Mean Time Between Failures
The definition of MTBF depends on the definition of what is considered a failure. For complex, repairable
systems, failures are those out of design conditions which place the system out of service and into a state
for repair. Failures which occur that can be left or maintained in an unrepaired condition, and do not place
the system out of service, are not considered failures under this definition.
In addition, units that are taken down for routine scheduled maintenance or inventory control are not
considered within the definition of failure.
1.63 Mean Time To Repair
Mean time to repair (MTTR) is a basic measure of the maintainability of repairable items. It is the total
corrective maintenance time for failures divided by the total number of corrective maintenance actions for
failures during a given period of time. It generally does not include lead time for parts not readily available
or other Administrative or Logistic Downtime.
It is be important to distinguish whether MTTR is meant to be a measure of the mean time between the
point at which the failure is first discovered until the point at which the equipment returns to operation
(usually termed "mean time to recovery"), or only a measure of the elapsed time between the point where
repairs actually begin until the point at which the equipment returns to operation (usually termed "mean
time to repair").
1.64 MEST for on-site services
MEST means Method Statement.

It refers to detailed instructions for on-site services, e.g. recurring monthly tests. Its basic purpose is to
ensure the desired outcome by controlling actions. The level of detail depends on the complexity of the
activity that is to be conducted and the impact of the failure in its execution. These methods can be pre-
authorized to improve efficiency in in delivery of services.
The term MEST is used interchangeably with MOP in the market.
1.65 Mission Critical Functions
A combination of technical supply systems within a larger facility, that secure the availability of power and
communications for that facility. The mission critical function (MCF) includes all underlying supply
systems that may be required to meet its functionality, e.g. batteries are required for UPS and
environmental controls are required for power distribution.
1.66 ModBus
Modbus is a serial communications protocol originally published in 1979 for use with programmable logic
controllers (PLCs). It is openly published, royalty-free and comes in several different protocol versions,
including support for TCP/IP.
1.67 MOP for on-site services
MOP means Method of Procedure.
It refers to detailed instructions for on-site services, e.g. recurring monthly tests. Its basic purpose is to
ensure the desired outcome by controlling actions. The level of detail depends on the complexity of the
activity that is to be conducted and the impact of the failure in its execution. These methods can be pre-
authorized to improve efficiency in in delivery of services.
The term MEST is used interchangeably with MOP in the market.
1.68 MTBF: see Mean Time Between Failures
1.69 MTTR: see Mean Time To Repair
1.70 Net Floor Area
Net Floor Area (NFA) is the part of a building that contains rentable floor area. It consists of Partition
Walls and Net Room Area (which contains Technical Area, Circulation Area, Amenity Area and Primary
Area). It can be with restricted or unrestricted access.
1.71 NFA: see MTBF: see Mean Time Between Failures
1.72 MTTR: see Mean Time To Repair
1.73 Net Floor Area
1.74 OCP Ready™ Facility Recognition Program
The OCP Facility Recognition program serve as a reference for data center operators and tenants who
want to understand the fundamental facility requirements to deploy this gear into their IT space. Facilities
that meet these guidelines and approved by the OCP DC Facilities Project receive the certification as an
OCP Ready™ facility.

1.75 Operational Governance Meeting
Recurring meetings on operational level between the customer representative and the site management
function.
1.76 Operational Sustainability
Defines the behaviors and risks beyond the technical robustness of a site that impact the ability to meet
its uptime objectives over a long term. The uptime is the resultant combination of both technical
robustness of the site infrastructure and Operational Sustainability.
1.77 PA: see Primary Area
1.78 Partition Walls
Partition Wall (PWA) is an interior wall which subdivides a part of a building into sections, rooms or
spaces. It may or may not support load other than its own weight and it may or may not be classified for
protection against unauthorized access.
1.79 PDSA: see Plan-Do-Study-Act Cycle
1.80 Perimeter protection
A physical security perimeter is defined as “any transition boundary between two areas of differing
security protection requirements”. This might be quite specific, e.g. the outermost boundaries of a site.
A critical facility should be appropriately protected against threats that may break the perimeter. By
protecting against external and environmental threats, i.e. man-made or natural disasters, it is focused on
ensuring that only designated access points can be used to gain entry to the critical facility.
1.81 Personal Protective Equipment
Personal Protective Equipment (PPE) is equipment that will protect the user against health or safety risks
at work. It can include items such as safety helmets, gloves, eye protection, high-visibility clothing, safety
footwear and safety harnesses. It also includes respiratory protective equipment (RPE).
1.82 Plan-Do-Study-Act Cycle
The PDSA cycle (or Deming cycle) is a model for developing, testing and implementing changes leading
to improvement.
It is based in scientiﬁc method and moderates the impulse to take immediate action without proper study
of facts. This way, the process of change is safer and less disruptive for site operations.
1.83 Planned Preventive Maintenance: see Maintenance, Preventive
1.84 PPE: see Personal Protective Equipment
1.85 PPM: see Maintenance, Preventive
1.86 Primary Area
Primary Area (PA) is the enclosed space used for work activity dependent on site capacity, e.g. white
space in a data center or operating theatre in a hospital. It can be with restricted or unrestricted access.

1.87 PUE
PUE (Power Usage Efficiency) is the ratio of the energy used by the customer computing Equipment to
the total energy consumption for the site (including site supply systems, e.g. environmental controls).
This term is sometimes incorrectly referred to as Power Usage Effectiveness.

distribution.
1.108
1.109 Site System
This refers to the full scope of technical supply systems within one infrastructure element to provide the
site functionality that enable the use of customer equipment, e.g. the full power distribution as defined in
the SLD (Single Line Diagram)
The term Site Supply System is used interchangeably with Site System in the market.
1.110 Site System Category
Site systems fall into five different categories; Building construction, Power distribution, Environmental
control, Telecommunications cabling infrastructure, and finally Security systems.
1.111 Site System Component
distribution.
The term Site Supply System Component is used interchangeably with Site System Component in the
market.
1.112 Site Technician: see Site Engineer
1.113 SLA: see Service Level Agreement
1.114 SNMP
Simple Network Management Protocol (SNMP) is an Internet Standard protocol for collecting and
organizing information about managed devices on IP networks and for modifying that information to
change device behavior.
Site Systems like UPS, BMS, CRAH etc. supports SNMP for management. Furthermore, customer
Equipment may also support SNMP.
1.115 SOP for Site Management
Standard Operating Procedures for Site Management Function.

These procedures define how the site is controlled and operated during normal circumstances. It is a set
of information that describes the characteristics of a process in terms that will enable its effective
execution, control and improvement.
The term SOP is used interchangeably with Standard Process Description in the market.
This should not be confused with MEST or MOP which regulates on-site work practices.
1.116 SOW: see Statement of Work
1.117 SR: see Service Request
1.118 Statement of Work
A statement of work (SoW) is a document routinely employed in the field. It defines specific activities,
deliverables and timelines for a vendor providing services to the client.
The SOW typically includes detailed requirements and pricing, with governance terms and practical
appendices, e.g. border list and asset list. It is often supported by a master service agreement or general
Terms & Conditions.
1.119 Strategic Governance Meeting
Recurring meetings on strategic level between the customer and the supplier of site services. This is the
