• Manage task sequencing and crew allocation within the shift and coordinate with the Planner before deferring scheduled work, adding break-in work, or making changes affecting the weekly schedule, except when immediate action is required to protect people, the environment, or equipment.
• Participate in daily maintenance review meetings and provide updates on work status, parts or tool needs, constraints, equipment condition, and expected completion.
• Provide accurate and timely explanations for completed, deferred, rescheduled, and break-in work so schedule-compliance reporting reflects actual field conditions.
