Sheet Structure

1. 1. Planning View (Dashboard): The central hub for strategic planning and real-time monitoring.
2. 2. Sales Forecasting Tracker: Detailed table containing historical sales data, forecasted values, and driver inputs.
3. 3. Maintenance Log & Impact Register: A structured log tracking maintenance events with their potential impact on sales capacity and delivery schedules.

Table Structures and Columns (Per Sheet)

1. Planning View (Dashboard)

This sheet functions as the executive summary, combining data from the other two sheets into an interactive planning dashboard. The table includes:

• Date Range: Weekly or Monthly planning periods.
• Forecasted Sales (Units): Projected sales volume based on historical trends and marketing initiatives.
• Actual Sales (Units): Actual sales achieved in the current period.
• Sales Variance (%): Difference between forecast and actual, calculated dynamically.
• Maintenance Downtime Risk Score: A composite metric derived from upcoming maintenance activities affecting production capacity.
• Adjusted Forecast (Units): Forecasted sales adjusted based on predicted maintenance-related delays or outages.
• Key Action Items: Auto-populated list of high-priority tasks based on overlapping forecasts and maintenance schedules.

2. Sales Forecasting Tracker

This sheet maintains granular sales forecasting data with the following columns:

• Period (e.g., Q1 2025, Week 14): Text – Identifies the time frame.
• Product/Service Category: Text – e.g., "Enterprise Software", "Hardware Kit A".
• Historical Sales (Units): Numeric (integer) – Previous period’s actual sales.
• Sales Growth Rate (%): Percentage – Calculated as (Current Period Sales – Previous Period Sales) / Previous Period Sales.
• Forecasted Demand (Units): Numeric (integer) – Manual input or formula-driven projection.
• Marketing Campaign Influence: Text/Boolean – e.g., "High", "Medium", "None" to indicate campaign impact.
• Target Sales (Units): Numeric (integer) – Internal sales target for the period.
• Status: Text – e.g., “On Track”, “At Risk”, “Behind” based on variance threshold.

3. Maintenance Log & Impact Register

This sheet is a comprehensive maintenance tracking system that directly ties operational reliability to sales performance:

• Maintenance ID: Unique auto-generated alphanumeric code (e.g., MAINT-001).
• Asset/Equipment Name: Text – e.g., "Production Line 3", "Warehouse Forklift B".
• Planned Maintenance Date: Date data type.
• Type of Maintenance: Dropdown list (e.g., Preventive, Corrective, Predictive).
• Duration (Days): Numeric – estimated downtime in days.
• Impact on Sales Capacity (%): Percentage – estimated reduction in production output during maintenance.
• Forecasted Sales Impact (Units): Numeric – calculated as: (Forecasted Demand × Impact on Capacity) / 100.


• Responsible Team: Text – team or technician responsible.
• Status: Dropdown – “Scheduled”, “In Progress”, “Completed”, “Delayed”.
• Notes: Text area for additional context (e.g., vendor delays, spare parts shortage).

Required Formulas and Calculations

• Sales Variance (%) in Planning View:
  =IF(Actual_Sales=0, 0, (Forecasted_Sales - Actual_Sales) / Actual_Sales * 100)
• Adjusted Forecast (Units):
  =Forecasted_Demand * (1 - MAX(Maintenance_Impact_Rate, 0)/100)
• Maintenance Downtime Risk Score:
  This is a weighted score combining the number of planned maintenance events and their average impact. For example:
  =COUNTIF(Maintenance_Status,"Scheduled") + (AVERAGEIFS(Impact_on_Sales_Capacity, Status,"Scheduled") / 10)
• Status in Sales Forecasting Tracker:
  =IF(Sales_Variance > 10%, "Behind", IF(Sales_Variance < -5%, "At Risk", "On Track"))

Conditional Formatting Rules

• Sales Variance: Red if > +10% (over-forecast), Green if < -5% (under-forecast).
• Status Column: Color-coded: Red = "Behind", Yellow = "At Risk", Green = "On Track".
• Maintenance Log – Status: Blue text for "Scheduled", Gray for "Completed".
• Downtime Risk Score: Amber if > 5, Red if > 10.
