• Gantt Chart Data: Main table where all tasks are defined with start/end dates, durations, dependencies.

• Progress Tracking: Logs actual progress (percentage complete), updates, and comments for each task.
• Milestones & Events: Lists critical points in time with associated descriptions, status flags, and deadlines.
• Resource Utilization: Provides a summary of workload distribution per team member to prevent overloading.
• Dashboard Summary: Automatically generated visual dashboard showing total project duration, on-time performance, delayed tasks, and progress trends.

Table Structures & Columns (Gantt Chart Data Sheet)

The core Gantt Chart Data table contains the following columns with defined data types:

• Task ID: Unique alphanumeric identifier (e.g., "PROJ-001"). Type: Text, auto-numbered.
• Task Name: Descriptive title of the task. Type: Text (max 50 characters).
• Start Date: Scheduled start date. Type: Date.
• End Date: Scheduled end date. Type: Date.
• Duration (Days): Automatically calculated as End - Start. Type: Number (int).
• Predecessor: Task ID that must be completed before this task begins. Type: Text or blank.
• Priority Level: High, Medium, Low. Type: Dropdown list with validation.
• Status: In Progress, On Schedule, Delayed, Completed. Type: Dropdown (validated).
• Responsible Team: Assigns ownership to a department (e.g., "Marketing", "Engineering"). Type: Text.
• Dependencies: Free or mandatory dependencies. Type: Text list.
• Notes: Additional details or risk factors. Type: Text (long field).

Formulas Required

The template uses a combination of Excel formulas to maintain accuracy and automate calculations:

• DURATION (Days): =IF(End Date="", "", End Date - Start Date)
• Duration Alert: =IF(Duration < 0, "Error", "") — detects invalid time ranges.
• Auto-Dependency Detection: Uses IF and VLOOKUP functions to cross-reference predecessor tasks with status.
• Progress % Formula: In Progress Tracking sheet: =IF(ISBLANK(Actual%), 0, Actual%) — allows manual updates.
• Slippage Detection: =IF(End Date < TODAY(), "Delayed", IF(Status="Completed", "On Track", "In Progress"))
• Resource Load Formula: In Resource Utilization sheet: =SUMIFS(Progress%, Team, [Team Name]) to calculate workload.
• Auto-Update Gantt Bar Width: Uses a helper column with =IF(Duration > 0, Duration/14.4, 0) for visual scaling in charts.

Conditional Formatting Rules

To enhance readability and highlight risks:

• Red Highlight on Delayed Tasks: If Status = "Delayed", apply red fill with dark text.
• Yellow for Overdue Start/End Dates: If Start Date < TODAY() or End Date < TODAY(), highlight yellow.
• Green for Completed Tasks: When Status = "Completed", apply green background and bold text.
• High Priority Flag: If Priority = "High", add a red triangle icon in the left column.
• Milestone Completion Indicator: When End Date matches a milestone date, show a green diamond shape in the Gantt bar.
• Resource Overload Warning: In Resource Utilization sheet, if % > 90%, highlight row with orange border.
