Inventory Turnover & Flow Optimization Design Template
The Inventory Turnover & Flow Optimization Design Template is a structured framework used to systematically analyze, model, and improve the velocity and efficiency of inventory movement across supply chain operations. It integrates quantitative metrics (e.g., turnover ratios, cycle times) with process design levers (e.g., replenishment policies, layout configuration) to minimize holding costs, reduce stockouts, and synchronize material flow with demand signals. The template serves as both an assessment tool and an implementation blueprint for continuous inventory flow improvement.

๐ Key Formulas
Inventory Turnover Ratio
COGS / Average Inventory
Measures how many times inventory is sold and replaced over a given period; higher values indicate stronger sales efficiency and lower obsolescence risk.
Days Sales of Inventory (DSI)
(Average Inventory / COGS) ร 365
Calculates the average number of days inventory remains in stock before being sold; used to assess liquidity and working capital efficiency.
Reorder Point (ROP)
(Average Daily Demand ร Lead Time) + Safety Stock
Determines the inventory level at which a new order must be placed to prevent stockouts while accounting for demand and supply variability.
