Table Structures and Columns

Main Gantt Chart Table (Sheet: Main Gantt Chart)

The main Gantt chart spans from January 2025 to December 2025, with each column representing a week. The visual bar for each task is dynamically linked to the Start Date and End Date via conditional formatting and Excel’s built-in timeline features.

Task Master List (Sheet: Task Master List)

Data Types:

• Task ID: Text (e.g., AUD-0XX)
• Description: Text (max 200 chars)
• Owner (Dept.): Dropdown list with predefined departments: Finance, IT, Legal, HR, Operations
• Dependency ID: Text referencing another Task ID or "None"
• Budget Code: Text (e.g., FNC-AUD-25A)

Formulas Required

• =IF(AND([@Status]="On Track", [@% Complete]>=0.9), "Completed", IF([@% Complete]<0.7, "At Risk", "On Track")) – Auto-classifies status.
• =DATEDIF([@Start Date], TODAY(), "d") / DATEDIF([@Start Date], [@End Date], "d") – Calculates percentage of duration elapsed (for % Complete).
• =SUMIFS(‘Task Master List’!% Complete, ‘Task Master List’!Owner, [@[Owner]], ‘Task Master List’!Type, “Planning & Design”) – Aggregates departmental progress.
• =IF([@End Date]<TODAY(), "Overdue", IF([@Start Date]>TODAY(), "Future", "Active")) – Identifies task status by time.

Conditional Formatting

• Task Progress Bars: Color scales from green (0%) to red (100%), with transparency gradients for visual clarity in printed versions.
• Status Indicators: Red fill for "Overdue," yellow for "At Risk," green for "On Track."
• Critical Path Highlighting: Applies bold border and blue background to tasks with zero slack (calculated via dependency logic).
• Milestone Dates: Icons (flag, star) applied when dates fall within 7 days of a deadline.

User Instructions

1. Open the template in Microsoft Excel (version 365 or later recommended).
2. Navigate to the "Task Master List" sheet and populate each task with accurate start/end dates, responsible departments, and dependencies.
3. Use the drop-down lists for Owner (Dept.) and Type to ensure consistency.
4. Update % Complete weekly—manually or via a linked status form if using Excel forms.
5. Review the "Dashboard Summary" sheet monthly to assess overall audit health, risk exposure, and resource strain.
6. Share the file with auditors (as read-only) or allow controlled access for cross-functional teams using Excel’s co-authoring feature.
