Table Structures & Data Types

Each sheet is structured to support data integrity and ease of analysis. Below are the core table designs:

1. Inventory Master List

Data types include: Text (SKU, Description), Categorical (Category), Numeric (Units, Reorder Level). All values are validated using data validation rules.

2. Quarterly Demand Forecast

This table uses numeric types for all sales figures. Formulas calculate percentage growth between quarters and compare actuals vs forecasts.

3. Reorder Points & Alerts

The "Reorder Point" is calculated dynamically using: Lead Time × Daily Consumption + Safety Stock. The status flag uses conditional formatting to highlight low stock.

Formulas Required

• Reorder Point Calculation: =D4 * E4 + F4 (where D = lead time, E = daily consumption, F = safety stock)
• Demand Growth Rate: =(B2-C2)/C2 to show % change from Q1 to Q2
• Stockout Risk: =IF(Inventory < Reorder Level, "RISK", "SAFE")
• Total Inventory Value (based on cost per unit): =Quantity × Unit Cost (in a summary sheet)
• Average Quarterly Usage: =AVERAGE(Q1:Q4) for each SKU to support planning.

Conditional Formatting

• Red Highlight: When stock level falls below reorder point or daily consumption exceeds 90% of forecast.
• Yellow Highlight: When inventory is between 70% and 89% of reorder level (warning zone).
• Green Highlight: When stock levels exceed safety stock by more than 25%. Indicates overstock.
• Data Bars: Applied to the "Quarterly Demand Forecast" to show sales volume trends visually.
