impact, production impact, environmental risk, maintainability, and lifecycle cost.\nServe as a technical resource for reliability methods, failure analysis, maintenance optimization, and asset-management decisions.\nundefined\n Reliability and Maintainability AnalysisConduct Failure Modes and Effects Analyses (FMEA/FMECA), fault-tree analyses, criticality analyses, and other structured reliability assessments for facility systems and equipment.\nDevelop reliability and maintainability allocations, predictions, and performance targets where appropriate for major facility systems and capital projects.\nAnalyze preliminary facility plans, equipment selections, and design concepts to identify potential reliability, maintainability, safety, and lifecycle-cost risks.\nRecommend design changes, redundancy, monitoring methods, spare-parts strategies, or maintenance approaches to improve system reliability.\nEvaluate the effect of system configuration, operating conditions, environmental factors, installation quality, and maintenance practices on asset performance.\n\nData Analysis, Statistical Methods, and Performance MonitoringCompile and analyze CMMS work-order data, preventive-maintenance compliance, equipment history, downtime records, condition-monitoring results, process-control statistics, and failure reports.\nIdentify trends and variables that may contribute to recurring failures, reduced availability, excessive maintenance, or increased operating cost.\nDevelop reliability dashboards and key performance indicators, including mean time between failures, mean time to repair, availability, planned-to-unplanned work, repeat failures, PM effectiveness, and maintenance backlog.\nApply statistical methods, trend analysis, and design-of-experiment concepts as appropriate to investigate reliability problems and validate corrective actions.\nDevelop or maintain mathematical and analytical models to identify assets, systems, or processes with excessive failure risk.\nPresent technical findings and recommendations clearly to technical and nontechnical audiences.\n\nFMEA, Root Cause, and Corrective ActionLead or support root-cause analysis, failure investigations, and corrective-action activities for facility and equipment failures.\nSupport the site’s failure reporting, analysis, and corrective-action processes, including documentation of failure modes, contributing causes, containment actions, and permanent corrective actions.\nVerify that corrective measures address the underlying failure mechanism and meet acceptable reliability, maintainability, safety, and operational standards.\nTrack corrective actions through closure and assess whether implemented actions produce sustained improvement.\nDevelop lessons learned and update maintenance procedures, asset strategies, design standards, and CMMS knowledge records based on completed investigations.\n\n Reliability - Centered Maintenance and CMMSDevelop, implement, and improve Reliability-Centered Maintenance (RCM) strategies for critical facilities assets.\nReview preventive-maintenance tasks, frequencies, job plans, and inspection methods to eliminate ineffective work and improve failure prevention.\nIntegrate predictive-maintenance techniques such as vibration analysis, infrared thermography, oil analysis, ultrasonic inspection, electrical testing, and condition monitoring where appropriate.\nDefine work-order requirements, failure codes, asset hierarchies, failure-mode libraries, and data-quality standards within the CMMS.\nAnalyze PM compliance, overdue work, repeat work orders, emergency maintenance, and maintenance-related downtime to identify improvement opportunities.\nRecommend spare-parts stocking levels and obsolescence strategies based on criticality, failure history, lead time, repairability, and business impact.\n\nCapital Projects, Design Reviews, and CommissioningParticipate in facilities capital projects from concept through closeout to ensure reliability, maintainability, operability, and lifecycle-cost requirements are addressed.\nReview design concepts, equipment specifications, contractor submittals, commissioning plans, and acceptance-test procedures for reliability risks.\nProvide reliability requirements for new equipment and facility systems, including maintainability access, condition monitoring, redundancy, spare capacity, maintainable design, and documentation.\nSupport equipment qualification, factory acceptance testing, site acceptance testing, functional testing, and performance verification.\nEvaluate proposed equipment replacements, upgrades, and modifications using lifecycle-cost, risk, reliability, and maintainability analyses.\nSupport
