• =SUMIFS(H:H, H:H, "Completed") / COUNTA(H:H) * 100: Calculates % of completed tasks (used in dashboards).
• =AVERAGE(C2:C100): Averages maintenance duration per entry.
• =SUMPRODUCT((G:G>=30), (H:H="Completed")): Totals hours of maintenance over 30 minutes that were completed.
• =VLOOKUP(A2, Maintenance_Log_Data!$A:$B, 2, FALSE): Cross-references technician performance.
