Table Structures and Columns

1. Tasks & Responsibilities (Main Data Table)

2. Team Assignments Table

Formulas Required

• Duration (Days): =End Date - Start Date + 1
• Progress Percentage: =COUNTIF(‘Tasks & Responsibilities’!$F:$F,"Completed") / COUNTA(‘Tasks & Responsibilities’!$B:$B)
• Overdue Tasks Count (per team member):=SUMPRODUCT((‘Tasks & Responsibilities’!$C:$C=A2)*(‘Tasks & Responsibilities’!$E:$E"Completed"))
• Next Due Date (for a team member):=MINIFS(‘Tasks & Responsibilities’!$E:$E, ‘Tasks & Responsibilities’!$C:$C, A2, ‘Tasks & Responsibilities’!$F:$F,"<>Completed")

Conditional Formatting

To enhance readability and urgency detection:

• Overdue Tasks: If End Date < Today, highlight cell in red.
• Pending Tasks (within 3 days): Highlight in yellow if End Date is within next 3 days and Status ≠ Completed.
• Status Column: Color-code based on status: Red for “On Hold”, Green for “Completed”, Orange for “In Progress”.
• Priority Level: Use color gradients: Red (High), Orange (Medium), Light Gray (Low).
