Table Structures and Columns

Timeline Schedule (Primary Table)

Formulas Required

• Duration Calculation: =IF(End Date > Start Date, End Date - Start Date + 1, 0) – Calculates task duration in days.
• Status Progress Bar: Uses a combination of IF and COUNTIFS functions to calculate % completion per project based on completed tasks.
• Overdue Alerts: =IF(AND(End Date < TODAY(), Status <> "Completed"), "Overdue", "") – Highlights overdue tasks.
• Resource Overload Detection: =COUNTIF('Resource Allocation'!B:B, Assigned To) – Counts how many tasks an employee has assigned to detect workload imbalance.
• Milestone Tracking: =IF(Milestone?="Yes", "✓", "") – Visual indicator for milestone tasks.

Conditional Formatting Rules

• Status Color Coding: Red for "Delayed", Yellow for "In Progress", Green for "Completed".
• Priorities: Use color scales to highlight High and Critical tasks (e.g., dark red backgrounds).
• Overdue Tasks: Apply a bold red border and white background to tasks with End Date before today’s date.
• Dates within 3 Days: Highlight any task ending in the next 3 days with a yellow background to prompt action.
