Table Structures and Column Definitions (Task List - Sheet 2)

The core of this Gantt Chart template is the Task List, which forms the backbone for all visual timelines and reporting. This sheet includes the following structured columns:

• Task ID (Text/Number): Unique identifier (e.g., OM-001, OM-002).
• Task Description (Text): Clear description of the office management activity.
• Department Responsible (Dropdown List): Options include Facilities, HR, IT, Finance, Admin.
• Assigned To (Text/Name List): Employee name or team responsible.
• Start Date (Date Type): When the task begins (formatted as mm/dd/yyyy).
• End Date (Date Type): When the task is expected to conclude.
• Duration (Days - Formula-Based): Calculated as =IF(End_Date > Start_Date, End_Date - Start_Date + 1, 0).
• Status (Dropdown: Not Started, In Progress, On Hold, Completed): Tracks task progress.
• Progress % (Number - 0 to 100%): Manual input or linked to status via formula.
• Dependencies (Text/List): References other Task IDs that must be completed before this task can start.
• Milestone Flag (Boolean: Yes/No): Marks if the task is a critical milestone.

Formulas Required for Dynamic Tracking

The template leverages advanced Excel formulas to automate tracking, improve accuracy, and enable real-time updates:

// Calculate duration in days
=IF(OR(ISBLANK([@Start_Date]), ISBLANK([@End_Date])), 0, [@End_Date] - [@Start_Date] + 1)

// Auto-update progress based on status (optional)
=IF([@Status]="Completed", 100, IF([@Status]="In Progress", 50, IF([@Status]="On Hold", 25, 0)))

// Detect overdue tasks
=IF(AND([@End_Date] < TODAY(), [@Status] <> "Completed"), "Overdue", "")

// Check dependency completion status (simplified)
=IF(COUNTIFS(TaskList[Task ID], [@Dependencies]) = 0, "Ready", "Dependent")

Conditional Formatting Rules

To enhance visual clarity and immediate recognition of critical statuses, the template applies conditional formatting across multiple sheets:

• Overdue Tasks: Red fill with white text in the Task List and Gantt Chart.
• Tasks 7 Days from Due: Yellow highlight to flag approaching deadlines.
• Completed Tasks: Green background in the Gantt Chart timeline.
• Status Indicators: Color-coded cells based on Status (e.g., blue for In Progress, gray for Completed).
• Resource Overload Detection: Red border around assigned resources exceeding 100% capacity in Resource Allocation Tracker.
