Sheet Names & Structure

The template consists of the following sheets:

1. Project Master – Central repository for all project details including name, priority, owner, budget, start/end dates.
2. Timeline Details – Main table with tasks, sub-tasks, durations, dependencies and progress tracking.
3. Milestones – Dedicated sheet for key achievement points with color-coded status indicators.
4. Resource Allocation – Tracks personnel assigned to tasks including availability and workload per team member.
5. Reports & Analytics – Pre-formatted dashboards showing project health, delay risks, resource utilization, and completion forecasts.
6. Calendar View (Summary) – A Gantt-style visual timeline view with color-coded bars for tasks and milestones.

Table Structures & Column Definitions

The core data structure is built around a relational table model, ensuring consistency and ease of filtering. Key columns include:

Formulas Required

The template uses several built-in Excel formulas to ensure dynamic calculations:

• End Date = Start Date + Duration: Automatically calculated in the Timeline Details sheet using `=Start_Date + Dur`.
• Progress (%) = (Actual Progress / Total Work) * 100: Calculated using a user-entered field for actual completion.
• Task Delay Detection = IF(Actual_End > Planned_End, "Delayed", ""): Flags overdue tasks in the Reports sheet.
• Dependency Check (via VBA or IF statements): Identifies if a task's dependency is missing or incomplete to flag risks.
• Resource Load Calculation: Sum of durations assigned to each person per week/month to detect overloading.

Conditional Formatting Rules

To enhance visibility and decision-making, the template applies conditional formatting:

• Red Highlight on Delayed Tasks: If Actual End > Planned End, task is highlighted in red.
• Yellow for "On Hold" or "In Progress": Indicates active monitoring.
• Green for "Completed": Signals successful delivery.
• Warning Bars on Overdue Milestones: Automatically color-coded in the Milestones sheet if due date is past.
• Color-Coded Priority Levels: High tasks appear in orange, medium in blue, low in gray.
• Diverging Color Scales for Progress (%): Shows progress from 0% to 100% with a gradient from red to green.

Step-by-step Setup:

1. Open the template and select the "Project Master" sheet to enter project details (e.g., Project ID, Name, Start Date, Owner).
2. In "Timeline Details", input task names, durations, start dates, dependencies (using task IDs), and assign owners.
3. Set priorities using the dropdown menu. Use status fields to update real-time progress.

• Resource Utilization Pie Chart: Shows workload distribution across team members to detect overallocation.
• Progress Over Time Line Graph: Tracks the completion rate of tasks weekly or monthly for trend analysis.
• Milestone Completion Heatmap: Visualizes project status at key points with color intensity reflecting achievement speed.
• Prioritization Radar Chart: Compares projects by priority, cost, risk, and timeline to aid decision-making.
