Key Formulas Required

• In “Next Due Date” column: =IF([@[Date of Service]]<>"", [@.[Date of Service]] + VLOOKUP([@Asset ID], AssetRegistry[[Asset ID]:[Maintenance Cycle (Days)]], 2, FALSE), "")
• “Days Since Last Maintenance”: =TODAY()-[@[Last Calibration]] (in Asset Registry)
• “Overdue Status Indicator”: In “Status” column of Asset Registry: =IF([@[Days Since Last Maintenance]] > [@[Maintenance Cycle (Days)]], "Overdue", IF([@[Status]]="Active", "On Schedule", [@[Status]]))
• “Total Annual Maintenance Cost”: =SUMIFS(MaintenanceLog[Cost ($)], MaintenanceLog[Date of Service], ">="&DATE(YEAR(TODAY()),1,1), MaintenanceLog[Date of Service], "<="&EOMONTH(TODAY(),0))

Conditional Formatting Rules

• Asset Registry: Highlight rows where “Status” = “Overdue” in bright red.
• Maintenance Log: Color-code “Status” column: Green = Completed, Yellow = Pending, Red = Overdue.
• Scheduled Maintenance: Shade future dates more than 30 days away in light gray; dates within 7 days in orange.
• Diagnostics Dashboard: Use data bars for “Cost per Asset” and traffic lights (Red/Yellow/Green) for “Compliance Score”.

User Instructions

1. Begin by populating the Asset Registry. Ensure each asset has a unique ID and accurate maintenance cycle.
2. Update the Vendor Management sheet with contacts, contracts, and SLA details.
3. Add all maintenance activities to the Maintenance Log. Use dropdowns for consistency.
4. The system auto-calculates due dates; do not manually edit “Next Due Date” unless overriding the schedule.
5. Weekly: Review the Diagnostics Dashboard for overdue assets or cost spikes.
6. Monthly: Run a Compliance Tracker audit and attach PDF reports to corresponding Log IDs.

• Pie Chart: Distribution of Maintenance Types — reveals if too many corrective actions occur (signaling poor planning).
• Gantt-Style Timeline: Scheduled vs. Completed Tasks for the next 6 months.
• KPI Cards: Real-time count of Overdue Assets, Total Cost YTD, Average Downtime Hours.
• Compliance Gauge: % of assets with valid calibration certificates (linked to Compliance Tracker).
