During a review of your transport team's recent missions, you identify a higher than usual number of delayed arrivals at the receiving facility. What would be the most appropriate first step to address this issue?
Suggest disciplinary action for the crews involved in the delayed missions.
Implement more mid-mission checkpoints to track progress more closely.
Change the crew schedules to ensure more timely arrivals.
Conduct a root cause analysis to identify the factors contributing to the delays.
