Sheet Names and Structure

Table Structure and Data Types

The template employs structured data tables with consistent data types across sheets:

Task List Sheet:

• Task ID (Text/Number): Unique identifier for each task (e.g., "OT-001")
• Task Name (Text): Descriptive title of the office management task
• Department (Text): Department responsible (e.g., Facilities, HR, Finance)
• Assigned To (Text/Name List): Employee name or team responsible
• Start Date (Date): When the task begins
• End Date (Date): Expected completion date
• DURATION (Number - Days): Calculated automatically using formula: =End_Date - Start_Date + 1
• Status (Dropdown): Options include "Not Started," "In Progress," "On Hold," "Completed"
• Priority (Dropdown): High, Medium, Low
• Dependencies (Text/List): Links to other task IDs that must be completed first

Resource Allocation Sheet:

• Employee Name (Text)
• Role/Department (Text)
• Total Available Hours/Week (Number)
• Allocated Hours per Task (Number): Breakdown by task ID

Formulas Required

The template incorporates essential Excel formulas to maintain accuracy and automation:

• DURATION Calculation: =IF(End_Date<>"", End_Date - Start_Date + 1, "")
• Progress Percentage: =IF(Status="Completed", 100%, IF(Status="In Progress", (TODAY()-Start_Date)/(End_Date-Start_Date)*100, 0))
• Task Status Indicator (Color Coding): Used in conditional formatting for visual cues
• Milestone Tracking: =IF(End_Date=Start_Date, "Milestone", "") — identifies single-day tasks
• Resource Load Calculation: =SUMIF(Task_List[Assigned To], Employee_Name, Task_List[Allocated_Hours]) / Total_Available_Hours * 100

Conditional Formatting Rules

To enhance readability and provide immediate visual feedback, the template applies these formatting rules:

• Overdue Tasks: Red fill with bold text if End_Date < TODAY()
• Upcoming Deadlines (within 7 days): Orange background
• Completed Tasks: Green fill with checkmark icon
• High Priority Tasks: Yellow highlight with bold text and exclamation mark symbol
• Resource Overload (more than 100% allocation): Red border and flashing animation on dashboard summary
