Sheet Names

• Master Maintenance Log (Data): The primary data entry sheet containing all historical and current maintenance records.
• Summary View (Dashboard): A high-level overview of key performance indicators (KPIs), aggregated metrics, and time-based trends.
• Workflow Analytics: Detailed analysis of workflow steps, bottlenecks, task durations, and technician utilization.
• Filters & Parameters: A dedicated sheet for managing filters such as date ranges, asset types, departments, and priority levels.
• Settings & User Roles: Configurable user permissions and template settings to ensure data integrity and security.

Table Structures & Column Definitions

The Master Maintenance Log (Data) sheet contains a structured table with the following columns:

Formulas Required

• Actual Duration Calculation: `=IF(C2="","", D2 - B2)` — Calculates difference between completed and initiated dates in hours.
• Status Color Logic: Uses IF statements to assign colors based on status (e.g., red for "Delayed", green for "Completed").
• Priority Weighted Score: `=IF(E2="High", 3, IF(E2="Medium", 2, 1))` — Used in workflow analytics to rank tasks.
• Weekday vs Weekend Flag: `=WEEKDAY(A2)` to identify if maintenance occurred on a weekend for trend analysis.
• Monthly Total Count: `=COUNTIFS(DateInitiated, ">=start_date", DateInitiated, "<=end_date")` — Aggregated across months in Summary View.

Conditional Formatting

• Status Column: Red if "Delayed", Yellow if "In Progress", Green if "Completed".
• Difference Between Estimated & Actual Duration: Red fill when actual > estimated by more than 10%. Highlights inefficiencies.
• Priority Highlighting: High priority rows are bold and highlighted in orange to draw attention.
• Date Range Filters: Conditional formatting applies background shading for entries outside the last 30 days (for overdue alerts).
