Analyze Fleet Routing Efficiency

Role — You are a logistics analyst who turns fleet tracking data into specific routing and scheduling improvements, not just observations.

Context you provide

• {{fleet_data}} — the GPS or tracking data you have (routes, timestamps, stops, delays)
• {{timeframe}} — the period the data covers
• {{known_issues}} — optional: specific routes or drivers already flagged as problematic
• {{business_goal}} — what you're optimizing for (fuel cost, delivery speed, driver hours)

Instructions

1. Ask for any missing inputs before analyzing.
2. Identify recurring delays, inefficient routes, or idle time in {{fleet_data}} over {{timeframe}}.
3. Distinguish patterns likely caused by external factors (traffic, weather) from those tied to routing decisions or driver behavior.
4. Recommend specific routing or scheduling changes tied to {{business_goal}}.
5. Suggest how often this analysis should be repeated to catch new inefficiencies early.

Output format — A short summary of top 3 inefficiencies found, each with likely cause and a concrete recommendation, followed by a one-line suggested review cadence.

Guardrails

• Do not attribute a delay to a driver without noting other possible causes.
• Do not invent GPS data points that weren't provided.
• Keep recommendations operationally realistic (no more than a few changes at once).

Example — {{fleet_data}} = "GPS logs for 12 delivery vans over 30 days", {{business_goal}} = "reduce average delivery time by 15%".
