Work Order Tracker

• Assigned_Employee – Name of assigned technician (Text)
• Last_Update – Timestamp of last modification (Auto-populated via formula)

Data Types & Formulas Required

All columns use standard Excel data types with appropriate validation rules:

• DateTime fields are formatted using the "dd/mm/yyyy hh:mm" format.
• Text fields include dropdowns for standardized values (e.g., Maintenance Type, Priority Level).
• Formulas:
  • =IF(Actual_End_Time="", "Not Started", "Completed") – Auto-determines status based on start/end times.
  • =NETWORKDAYS(Scheduled_Date, TODAY()) – Calculates days overdue for scheduled maintenance.
  • =SUMIFS(Duration_Hours, Maintenance_Type, "Preventive") – Sum of preventive hours by type.
  • =MAX(Due_Date) - TODAY() – Shows days until next critical work order deadline.

  Conditional Formatting Rules

  The template applies dynamic conditional formatting for key performance indicators:

  • Status Highlighting: Red if "Pending", Yellow if "In Progress", Green if "Completed".
  • Overdue Alerts: Cells in the “Scheduled_Date” column turn orange when work is overdue by more than 3 days.
  • High-Cost Flagging: Rows where Cost_Centers exceed $10,000 are highlighted in red with a warning icon.
  • Maintenance Frequency Heatmap: In Asset Health Monitor, cells show color gradients based on how often maintenance occurs (e.g., green = low frequency, red = high frequency).
