Sheet Names

• Task Overview: Primary sheet containing all task data, dates, responsible personnel, and status information.
• Gantt Chart View: Visual representation of tasks across time using a timeline format with progress bars.
• Status Dashboard: A summary dashboard providing key performance indicators (KPIs) for administrative projects.
• Resource Allocation: Tracks availability and workload distribution among administrative team members.
• Notes & References: For storing documentation, instructions, templates, or external links related to specific tasks.

Table Structures and Columns

1. Task Overview Sheet

• Task ID: Text (e.g., A-01, B-12) — Unique identifier for tracking.
• Task Description: Text — Clear, concise description of the task.
• Responsible Person: Text — Name of the individual accountable for completion.
• Department/Team: Text — Organizational unit responsible or affected.
• Start Date (Quarterly): Date (MM/DD/YYYY) — First day of the task’s execution in the quarter.
• End Date (Quarterly): Date (MM/DD/YYYY) — Final day for completion within the quarter.
• Duration: Number (Days) — Automatically calculated using formula: =End Date - Start Date + 1
• Status: Dropdown List: Not Started, In Progress, Blocked, Completed, On Hold
• Priority Level: Dropdown List: High, Medium, Low — For task prioritization.
• Dependencies (IDs): Text — Comma-separated Task IDs that must be completed before this task can start.

2. Gantt Chart View Sheet

This sheet contains a visual timeline representation using stacked bar charts. The horizontal axis represents the quarterly timeline (e.g., January 1 – March 31, 2025), and each row represents a task.

Formulas Required

• Duration (Task Overview): =IF(OR(Start_Date="", End_Date=""), "", End_Date - Start_Date + 1)
• Progress Percentage: Uses a separate input field or formula that references actual vs. planned completion.
• Dependency Validation: Uses =IF(AND(Dependencies<>"", NOT(ISNUMBER(MATCH(Dependencies, Task_ID_List, 0)))), "Invalid Dependency") to flag errors.
• Quarter Start/End Dates (Gantt): Formulas dynamically set the X-axis scale based on the current quarter.

Conditional Formatting

The template uses conditional formatting to enhance readability and highlight critical information:

• Status Color Coding: Red for "Blocked", Yellow for "In Progress", Green for "Completed", Gray for "Not Started".
• Overdue Tasks: Automatically highlights tasks where End Date < TODAY() and Status ≠ Completed.
• High Priority Tasks: Background color in red if Priority = High.
• Gantt Progress Bars: Uses data bars (color gradient from blue to green) to visualize task progression over time.

Instructions for the User

1. Set the Quarter: Update the "Quarter Start" and "Quarter End" dates in cell A1 of the Gantt Chart sheet to reflect your current quarter.
2. Add Tasks: Enter each administrative task in the Task Overview sheet with accurate start/end dates and responsible personnel.
