Formulas Required

The template includes several automated calculations to support business reporting and decision-making:

• Total Maintenance Cost per Project: =SUMIF($E$2:$E$100, A2, $I$2:$I$100) — Sums cost by project name.
• Count of Completed Tasks: =COUNTIFS(Status, "Completed") — Tracks progress.
• Days Since Last Maintenance: =IF(ISBLANK(F2), "", TODAY() - F2) — Calculates age of last service.
• Number of Delayed Tasks: =COUNTIFS(Status, "Delayed") — Flags overdue work.
• Average Duration per Task Type: =AVERAGEIF(Type_of_Maintenance, A2, Duration) — Enables trend analysis by task type.
• Cost Per Hour: =IF(Duration > 0, Cost / Duration, "") — Helps evaluate efficiency and labor costs.
• Future Due Alerts: =IF(Next_Due_Date < TODAY(), "⚠️ Overdue", "") — Flags upcoming due dates.

Conditional Formatting

To enhance visibility and alert users to critical events, conditional formatting is applied:

• Red Highlight (Criticality Level): When “Critical” or “High”, cells are highlighted in red.
• Yellow for Delayed: If "Status" = "Delayed", row turns yellow with bold text.
• Green for Completed: Tasks marked as completed appear in green to indicate progress.
• Warning Borders on Overdue Entries: Cells where Next Due Date is past today are bordered in orange.
• Color Scales by Duration: A gradient from light blue (short) to red (long) shows task duration trends.
