Optimize preventive maintenance and spares: Create risk-based PM strategies, equipment BOMs, critical-spares lists, stocking recommendations, and obsolescence mitigation plans using equipment criticality, failure modes, OEM guidance, and operating history.

Lead equipment changes and projects: Define technical requirements and lead design reviews, vendor selection, FAT/SAT, commissioning, qualification, turnover, training, maintenance readiness, and documentation for modifications and new equipment.

Own technical quality actions: Lead equipment-specific change controls and CAPAs, provide timely deviation assessments, and ensure approved hardware changes are implemented, tested, documented, and effectively closed.

Drive reliability improvement: Use downtime, repeat work, deviations, maintenance findings, and condition data to eliminate bad actors and improve reliability, maintainability, safety, and compliance.

Coordinate vendors and stakeholders: Develop technical scopes, assess vendor capability and performance, and collaborate with Operations, Quality, Validation, Metrology, HSE, Automation, Engineering, Procurement, Stores, and Finance.
