Sheet Names

The template includes the following core sheets:

• Maintenance Log Master – The primary data repository for all maintenance activities.
• Asset Inventory – A detailed registry of all operational assets with lifecycle and ownership details.
• Report Summary – Auto-generated summaries, including monthly trends, downtime analysis, and cost metrics.
• Downtime Analytics – Specialized analysis focused on equipment unavailability and root cause identification.
• User Input Form (Dynamic) – A user-friendly form that populates the Maintenance Log Master with minimal manual errors.
• Forecast & Budget Planner – Predictive modeling for future maintenance needs and associated costs.
(Note: The template supports up to 50,000 rows in the Master Log and is optimized for performance with filtered views.)

Table Structures & Column Definitions

The Maintenance Log Master table features a normalized, relational structure to prevent data redundancy and ensure consistency.

Formulas Required

The template relies on powerful Excel functions to ensure real-time calculations and automation:

• =IF(NEXT_MAINT_DATE < TODAY(), "Due", "Pending") – Flags upcoming maintenance tasks.
• =VLOOKUP(AssetID, AssetInventory!A:B, 2, FALSE) – Retrieves asset name from inventory when Asset ID is entered.
• =SUMIFS(Costs!, Type="Corrective", Status="Completed") – Calculates total corrective maintenance spending.
• =AVERAGEIF(Downtime!, Type="Preventive") – Measures average downtime for preventive actions.
• =COUNTIFS(Type, "Critical", Status, "Completed") – Counts critical tasks completed per month.
• =NETWORKDAYS(Start_Date, End_Date) – Calculates workdays between start and end dates (for downtime analysis).
• =DATEDIF(First_Maintenance, Next_Maintenance, "m") – Computes months since last service.

Conditional Formatting Rules

The template employs intelligent conditional formatting to highlight critical issues:

• Red Highlight: When Downtime > 8 hours or Priority = Critical.
• Yellow Highlight: When Status is "Pending" and Date & Time is beyond 7 days from due date.
• Green Fill: For entries with Type = "Preventive" and Status = "Completed".
• Color Scale (Gradient): Applied to the Cost ($) column to visualize spending trends across months.
• Text Highlighting: “Next Maintenance Due” in bold for entries with due dates within 3 days.
