Formulas Required

The template uses a variety of Excel formulas to ensure dynamic, real-time updates:

• =NETWORKDAYS(Start_Date, End_Date): Calculates working days (excluding weekends).
• =IF(C5 > D5, "Overdue", IF(C5 = D5, "On Time", "Ahead")): Determines task status against schedule.
• =VLOOKUP(Project_ID, Project_Master!A:B, 2, FALSE): Pulls project details into the Gantt sheet.
• =IF(AND(A4="", B4=""), "", "Milestone"): Flags tasks that are milestones (e.g., review meetings).
• =SUMIFS(Resource_Allocation!Daily_Hours_Assigned, Task_ID, A2): Calculates total hours per task.
• =COUNTIF(Progress_Tracking!Status, "Completed"): Counts completed tasks for progress metrics.

Conditional Formatting

Dynamic conditional formatting enhances visibility and alerting:

• Task bars in Gantt Chart View: Green if on time, yellow if delayed by 1–3 days, red if over 3 days late.
• Status cells in Project Master: Highlighted based on priority level (High/Critical = red; Low = green).
• Overdue tasks: Entire task row is shaded with orange background when end date is passed.
• Milestones: Font color changes to bold blue in Gantt chart.
• Resource conflicts: If two tasks assign the same employee to overlapping periods, rows are highlighted in red.
