• Model request completion times by training on Creation Date and Completion Date fields.
• Classify Type of Service Request (e.g., regular vs. crisis) based on geographic features like Police District or Wards.
• Identify duplicate service requests by filtering the Status field for 'Open - Dup' or 'Completed - Dup' entries.

Strengths
