Table Structures and Column Definitions (Audit Plan & Timeline Sheet)

This sheet serves as the primary Gantt chart visualization, displaying audit tasks across a weekly timeline.

Formula Requirements

1. Duration Calculation:
   =IF(End_Date <> "", (End_Date - Start_Date)/7, 0)
   Ensures that duration is calculated in whole weeks and remains blank until both dates are set.
2. Gantt Bar Width (Dynamic):
   =IF(Status="Completed", 1, IF(Status="Delayed", 0.5, IF(Start_Date < TODAY(), 0.8, 0.4)))
   Used in conditional formatting to scale bar length based on progress and status.
3. Week Number Identifier:
   =WEEKNUM(Start_Date)
   Automatically identifies the week number for each task, enabling weekly grouping and sorting.

Conditional Formatting Rules

• Status-Based Color Coding: Apply color scales based on Status:
  • Not Started: Light gray background
  • In Progress: Yellow highlight with dark text
  • Completed: Green background with white text
  • Delayed: Orange-red alert color, bold font
• Dates Near Deadline: Highlight any task where the End Date is within 3 days of today using a red border. =AND(End_Date < TODAY() + 3, Status<>"Completed")
• Gantt Bars (Visuals): Use a combination of cell background fill and conditional formatting to render horizontal bars representing task duration. For example, in the "Gantt" column: =AND($E2 <= TODAY(), $F2 >= TODAY()) — highlights current week's progress.

Instructions for the User

1. Set Start Date: Begin by entering the first Monday of your audit cycle in the designated “Start Date” cell (e.g., 01/01/2025).
2. Add Tasks: Populate the Task Name, Phase, Owner, and expected Start/End Dates. Use only weekdays for dates.
3. Link Dependencies: In the "Task Details & Dependencies" sheet, use the Task ID to link tasks (e.g., “Task A-003 cannot start until A-002 is completed”).
4. Update Status Weekly: Every Monday, review task statuses and update them. The Gantt chart will reflect progress dynamically.
5. Track Delays: If a task is delayed, immediately update the Status to “Delayed” and adjust the End Date accordingly.
6. Export for Reporting: Use the built-in Dashboard (optional) to generate summary reports or export data for stakeholder presentations.
