Sheet Names

• Project Overview – Central summary sheet containing project metadata such as name, goals, start/end dates, budget, stakeholders, and key success indicators.
• Project Timeline (Main) – Core table showing all tasks with their scheduled start/end dates, durations, dependencies, and status.
• Dependencies – A relational table linking tasks based on predecessors/successors to visualize critical path logic.
• Resource Allocation – Tracks personnel assigned to each task with work hours or days per task and availability notes.
• Status Log – Daily or weekly update log for progress, risks, changes, and issue resolution tracking.
• Reports & Dashboards – Pre-formatted charts and summary views accessible via embedded pivot tables and conditional formatting alerts.

Table Structures & Column Definitions

The core data structure is organized around a relational model to ensure consistency and scalability. All tables are designed with standardized column names, consistent data types, and references to maintain integrity across sheets.

Project Timeline (Main) Table

All dates are stored as Excel serial numbers (Date data type), while progress percentages are stored as numeric values between 0 and 100. Task IDs are unique identifiers that support filtering, sorting, and linking across other sheets.

Dependencies Table

Resource Allocation Table

Data Types & Formulas Required

All data types are strictly defined to ensure compatibility and prevent errors. Key formulas include:

• DURATION (days): =IF(End_Date="", "", End_Date - Start_Date)
• Progress (%): =IF(Status="Completed", 100, IF(Status="In Progress", (Actual_Hours / Planned_Hours) * 100, 0))
• Automatic Task Dependencies Check: Uses VLOOKUP with a conditional formula to validate predecessor relationships in the "Dependencies" table.
• Estimated Completion Date: =Start_Date + Duration (in days)
• Project Duration (Total): =MAX(End_Date) - MIN(Start_Date) in Project Overview sheet.

Conditional Formatting Rules

• Status Highlighting: Cells with "In Progress" turn yellow; "Delayed" turn red; "Completed" turn green.
• Overdue Tasks: If End_Date < TODAY(), the task row is highlighted in red with bold text.
• Priority Levels: High → Orange, Moderate → Blue, Low → Gray.
• Progress Bar: A conditional format draws a progress bar from left to right using a color gradient (0% = gray, 100% = green).
• Date Alerts: Auto-highlights tasks where the start date is more than 7 days in the future.
