1. Workbook Architecture & Tab Breakdown
The architecture follows a relational database model to ensure data integrity and auditability.
- [Dashboard]: Executive-level visualization (KPI Cards, Status Heatmaps).
- [Asset_Registry]: The "Single Source of Truth." Contains static metadata (Asset ID, location, install date, warranty status, manufacturer specs).
- [Maintenance_Log]: The transactional layer. Every service event is recorded here against an Asset ID.
- [Validation_Lists]: Hidden lookup tables for drop-down menus (Technicians, Status, Priority, Asset Class).
- [Calculation_Engine]: Hidden sheet performing cross-tab lookups and variance analysis to keep the dashboard clean.

3. Explicit Formula Glossary
=XLOOKUP(A2, Maintenance_Log!A:A, Maintenance_Log!D:D, "No History")- Retrieves the most recent maintenance status from the log sheet based on the Asset ID.
=WORKDAY(E2, F2)- Calculates the next due date by adding the service interval to the last service date, skipping weekends.
=IF(G2<TODAY(), "OVERDUE", "ON TRACK")- Logic gate for status monitoring. Flags assets where
Next_Due_Datehas passed the current date.
- Logic gate for status monitoring. Flags assets where
=AVERAGEIF(C:C, "Roof*", H:H)- Calculates average priority score for all rooftop units using wildcard criteria.
=IFERROR(VLOOKUP(...), "Data Missing")- Ensures the UI doesn't break if an Asset ID is missing from the registry.
4. Data Validation & Conditional Formatting Rules
Data Validation (Dropdowns)
- Status Column:
Data > Data Validation > List->Active, Offline, Decommissioned, In-Repair - Priority Column:
Data > Data Validation > List->P1, P2, P3 - Technician Column:
Data > Data Validation > List->=Validation_Lists!$A$2:$A$10
Conditional Formatting
- Overdue Flag: Range
G2:G500. Rule:Cell Value < TODAY(). Format: Bold, Red Fill, White Text. - Priority High (P1): Range
H2:H500. Rule:Cell Value = "P1". Format: Light Red Fill. - Maintenance Status: Range
D2:D500. Rule:Cell Value = "Offline". Format: Gray strikethrough.
5. Executive Summary KPI Cards
| Metric | Calculation / Logic | Output |
|---|---|---|
| Total Fleet | =COUNTA(Asset_Registry!A2:A500) | 12 |
| Compliance Rate | =COUNTIF(StatusRange, "ON TRACK")/COUNTA(TotalRange) | 91.6% |
| P1 Backlog | =COUNTIFS(PriorityRange, "P1", StatusRange, "OVERDUE") | 1 |
| Mean Time to Maintain (MTTM) | =AVERAGE(IntervalRange) | 158 Days |
Note: All KPI calculations are dynamically linked to the Master Data Table for real-time reporting.
