Formulas Required

The template leverages Excel’s advanced formula engine for automation, accuracy, and dynamic updates:

• DURATION (Days): `=IF([End Date]<>""; [End Date]-[Start Date]; 0)`
• Progress %: `=IF([Status]="Complete";100; IF([Status]="In Progress"; [Actual Completed]/[Total Planned]*100; 0))`
• Task Completion Status Update (dynamic): Uses `=IF(AND([Progress%]>=95;"Completed";IF([Progress%]<=25;"Pending";"In Progress")))`
• Team Load Calculation: `=COUNTIFS('Task List & Progress'!$E:$E, [Team Member], 'Task List & Progress'!$G:$G, ">=0") / 10 * 100` to compute workload percentage.
• Dependency Validation: `=IF(OR([Start Date] < [Previous Task End Date]; [End Date] > [Next Task Start Date]); "Conflict Detected"; "")`
• Automatic Status Color Coding: Uses nested IF statements to assign status labels based on progress thresholds.

Conditional Formatting Rules

The template applies conditional formatting to enhance visual clarity and alert users to urgent or at-risk items:

• Task Progress Bar (in Task List): Gradient fill from green (0–50%) → yellow (51–80%) → red (>80%)
• Status Highlighting: Red for "Delayed", Yellow for "At Risk", Green for "On Track"
• Overloaded Team Members: Cells with load > 85% are highlighted in orange with bold text.
• Risks with High Impact & Probability: Highlighted in red background, with bold font.
• Tasks Due Next Week: Background color changes to light blue if start date is within 7 days of today.
