Table Structures & Columns

The main data structure is a hierarchical table in the “Project Timeline (Main)” sheet with the following columns:

• Task Name: Descriptive name of the activity – Data type: Text
• Project Name: Links to the overarching project (e.g., “Digital Transformation Initiative”) – Data type: Text
• Start Date: When the task begins – Data type: Date/Time
• End Date: When the task is expected to complete – Data type: Date/Time
• Duration (Days): Automatically calculated from start and end dates – Data type: Number (Formula-driven)
• Predecessor Task(s): References earlier tasks that must be completed before this one – Data type: Text or Dropdown
• Status: Enumerated values: “Not Started,” “In Progress,” “On Hold,” “Completed” – Data type: Text (Dropdown list)
• Progress (%): Manual input or auto-calculated based on actual vs. planned completion – Data type: Number (0–100%)
• Assignee: Name of team member responsible – Data type: Text
• Priority Level: High, Medium, Low – Dropdown field for prioritization
• Resource Requirement (Budget): Estimated cost in USD – Data type: Currency
• Actual End Date (if completed): Date when task was actually finished – Data type: Date/Time
• Notes: Optional field for comments or contextual details – Data type: Text

Formulas Required

The template leverages powerful Excel formulas to automate key metrics:

• =ENDDATE - STARTDATE + 1 calculates the duration in days.
• =IF(Progress% = 100, "Completed", IF(Progress% > 50, "In Progress", "Not Started")) dynamically determines status based on progress.
• =SUMIF(Status, "In Progress", Duration) sums total days currently underway.
• =COUNTIFS(Status, "Completed") / COUNTA(Task ID) * 100 calculates completion percentage across all tasks.
• =IF(Actual End Date >= End Date, "Delay Detected", "") flags delayed tasks for review.
• =VLOOKUP(Task ID, Resources & Assignments!A:B, 2, FALSE) pulls assignee data automatically.

Conditional Formatting Rules

To enhance visibility and decision-making:

• Red Highlight: When a task is overdue (Actual End Date > End Date).
• Yellow Background: If progress is below 50% or status is “On Hold”.
• Green Background: Tasks completed or at ≥90% completion.
• Highlight by Priority: High-priority tasks are shaded in orange with bold font.
• Dates in Future: Cells for start/end dates beyond one month from today are highlighted in light blue to indicate future planning.

User Instructions
