CRL Certified Reliability Leader PRACTICE EXAM QUESTIONS WITH CORRECT DETAILED ANSWERS | ALREADY GRADED A+recent version 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 33) Problem chain - ANSWER The series of symptoms that initiated a problem 34) Root cause - ANSWER Failure or fault from which a chain of effects or failures originates 35) Root cause analysis (RCA) - ANSWER Identification and evaluation of the reason for an undesirable condition or nonconformance; a methodology that leads to the discovery of the cause of a problem or root cause 36) Root cause failure analysis (RCFA) - ANSWER Investigative technique applied to the determination of factors leading to an initiating or original failure 37) Symptom - ANSWER A condition that is produced by a problem, not the actual problem 38) Acceptance criteria - ANSWER Requirements a project or system must meet before customer can accept delivery 39) Acceptance test - ANSWER A test conducted under specified conditions, using delivered items to determine compliance with specified requirements 40) Acquisition - ANSWER Obtaining equipment or assets for use by an organization in its business 41) Asset lifecycle - ANSWER Stages or phase phases involved in the management of an asset during its life. These phases include concept, design and development, build, install and commission, operation, maintenance, decommissioning and disposal 42) Asset performance management - ANSWER A set of work processes used to maximize asset performance, mitigate risk, and maximize return on investment for a business
