Data Types & Formulas Required

All data types are standardized to ensure consistency:

• Start Date and End Date: Text formatted as "MM/DD/YYYY" — automatically converted to date fields.
• Durational Days (Duration): Calculated using: =END_DATE - START_DATE
• Progress (%): User input, with a default of 0%. Can be updated manually or via conditional logic.
• Actual Effort: Manual input; compared to Estimated Effort to show variance.
• Status: Dropdown list: “Not Started”, “In Progress”, “On Hold”, “Completed”, “Delayed”.
• Priority: Dropdown: Low, Medium, High, Urgent (for filtering).

Key formulas include:

• =IF(Progress% >= 100%, "Completed", IF(Progress% > 50%, "In Progress", "Not Started")) — dynamically updates status.
• =IF(Estimated Effort - Actual Effort > 5, “Over Budget”, “On Track”) — flags over-effort.
• =IF(ISBLANK(Owner), "Unassigned", Owner) — ensures no missing assignments.

Conditional Formatting Rules

The template uses dynamic conditional formatting to enhance visibility:

• Red background for delayed tasks: If End Date < Today() and Status is “In Progress”.
• Yellow highlight for progress below 50%: When Progress % < 50% and Task ID is not "Completed".
• Green fill when status = "Completed" or progress ≥ 90%.
• Highlight high priority tasks with orange borders: Where Priority = “Urgent” or “High”.
• Task bars in Gantt chart automatically scale by duration and progress.
