1) Asset - ANSWER Something that has potential or actual value to an organization
2) Asset (equipment) capacity - ANSWER The ability of equipment to produce a
product or provide a service at a given performance rate over a specified time period
3) Asset management - ANSWER A set of coordinated activities that an organization
uses to realize value from assets in the delivery of its aim
4) Computerized maintenance management system (CMMS) - ANSWER A software
system that keeps records and tracks all maintenance activities, synonymous with
enterprise asset management system (EAMS)
5) Criticality analysis - ANSWER A methodology used to evaluate how asset failures
impact organizational performance to systematically rank facility assets for the
purpose of work prioritization, preventative maintenance (PM)/predictive
maintenance (PdM), development and optimization, material classification, capital
improvement projects, etc
6) Data collection - ANSWER Obtaining asset and facility information to develop
and support performance improvement efforts
,7) Failure - ANSWER Inability of an asset or component to perform its designed
function. It does not require the asset to be inoperable; reduced speed or not meeting
operational or quality requirements
8) Failure mode & effects analysis (FMEA) - ANSWER A technique to examine an
asset, process, or design to determine potential ways it can fail and its potential effects
on required functions, and to identify appropriate mitigation tasks for highest priority
risks. Also known as failure mode, affects and criticality analysis (FMECA)
9) Lifecycle costing - ANSWER A technique that examines all costs associated with
assets/items during their life cycles including design, development, build, operate,
maintain and disposal
10) Maintenance program - ANSWER A comprehensive set of maintenance activities,
their intervals and required activities, along with accurate documentation of these
activities
11) Maintenance strategies - ANSWER A long-term plan covering all aspects of
maintenance management that sets the direction on how assets will be maintained and
contains action plans for achieving the desired future state
12) Mean time between failure (MTBF) - ANSWER A basic measure of asset
reliability calculated by dividing the total operating time of the asset by the number of
failures over a period; the inverse of failure rate and is generally used for repairable
systems
13) Mean time to repair (MTTR) - ANSWER A basic measure of maintainability, it
represents the average time needed to restore an asset to its full operational condition
after failure; calculated by dividing total repair time of the asset by the number of
failures over a time period
14) Predictive maintenance (PdM) - ANSWER Advanced maintenance technique
focused on using technology, such as oil analysis, vibration, or ultrasound, to
determine condition of assets and then taking appropriate actions to avoid failures.
Synonymous with condition based maintenance (CBM) and On-Condition
Maintenance
,15) Preventive maintenance (PM) - ANSWER A maintenance strategy based on
equipment inspection and servicing (component replacement and overhaul) that are
preplanned at a specific point in time
16) Risk priority number (RPN) - ANSWER A technique used for analyzing the risk
associated with potential problems identified during a FMEA; expresses the degree of
risk associated with potential problems regarding severity and probability. Usually
calculated before, and after the improvements. Mathematically, RPN = Severity x
Occurrence x Detection
17) Condition-directed (CD) tasks - ANSWER Test directly aimed at detecting the
onset of a failure or failure symptom
18) Critical asset - ANSWER An asset that has been evaluated and classified as critical
due to its potential impact on safety, the environment, quality, production/operations
and maintenance if it fails
19) Failure finding (FF) tasks - ANSWER Scheduled tasks that seek to determine if a
hidden failure has occurred or is about to occur
20) Failure mode - ANSWER The ways in which something might; different ways and
asset or component can fail to perform as intended
21) Hidden failure - ANSWER A failure mode that is not evident to a person or
operating crew under normal circumstances
22) Operating context - ANSWER The environment in which an asset is expected to
be used
23) Preventive maintenance optimization (PMO) - ANSWER A methodology,
focusing on proving maintenance effectiveness and efficiency by reviewing an
existing maintenance program and, in most cases, adding maintenance task to account
for failure, modes, not addressed by existing program
, 24) Reliability-centered maintenance (RCM) - ANSWER A systematic, disciplined
process for establishing the appropriate maintenance plan for an asset/system to
minimize the probability of failures. The process ensure safety, system function and
mission compliance
25) Availability - ANSWER The probability that an asset is capable of performing its
intended function satisfactorily, when needed, in a stated environment. Availability is
a function of reliability and maintainability
26) Failure rate - ANSWER Number of failures of an asset over a period of time.
Failure rate is considered constant over the useful life of an asset. It is normally
expressed as the number of failures per unit of time. Noted by lambda, failure rate is
the inverse of meantime between failures
27) Maintainability - ANSWER The ease in speed in which a maintenance activity can
be carried out on an asset. A function of equipment designed that is usually measured
by meantime to repair
28) Reliability - ANSWER The probability that an asset, item, or system will perform
its require required function satisfactorily under specific conditions within a certain
time period
29) Run to failure (RTF) - ANSWER A maintenance strategy or policy for assets,
where the cost and impact of failure is less than the cost of preventive action. It is a
deliberate decision based on economical effectiveness
30) Uptime - ANSWER The time during which an asset or system is either fully
operational or ready to perform its intended function
31) Checklist - ANSWER A structured, prepared form for collecting, recording, and
analyzing data as work progresses. The generic tool can be developed for a wide
variety of purposes, such as an operator's startup checklist, and a maintainability
checklist, used by designers
32) Problem - ANSWER A perceived gap between the existing state and a desired
state, or a deviation from a norm, standard, or status quo
