Supply Chain White Paper on Life Cycle Management Managing Short Life-Cycle Technology
This paper covers findings from an operations research initiative I am co-chairing with Lehigh University.  It involves the use of statistical clusters in leading indicator analysis with applications in life-cycle and capacity management.
Flexibility Presentation with Lean Case Study Driving Flexibility
I presented these slides at the Supply Chain World Conference in Chicago.  The material provides a framework for understanding demand, improving the signal and executing a relevant fulfillment strategy for the uncertainty that remains.
White Paper on Dealing with Outsourcing Optimizing Horizontal Supply Chains
 This paper discusses problems and solutions relating to trading partners (such as manufacturing subcontractors) being introduced between a supplier and a customer.  It includes a mini case study as well.
Presentation on Managing Uncertainty in the Supply Chain Design for Uncertainty
I gave this presentation at the IBF Forecasting Best Practices Conference in New Orleans.  The slides provide a framework for designing business processes to embrace uncertainty.  Includes a mini case study.
Best Practice Profile on Demand Management & Inventory Control Demand Focused Responsiveness
This is a best practice profile of my patent pending methodology for demand management and inventory control.  It was written up by the Supply Chain Executive Board, headquartered in Washington D.C.

Inventory Turnover (Turns) Calculator

Inventory Turnover or Turns is the number of times an organization cycles its inventory in a year.  It is commonly used as a measure of how efficiently a supply chain invests its cash in inventory.  Lower turnover is a sign of inefficiency.  Turns is calcu-lated by dividing demand by average inventory.  Calculate your turns by entering the values below.
 
BOP
Inventory $		 EOP
Inventory $		 COGS $ for Period Days in

Turns:
You can also calculate your unit turnover by inputting the number of units instead of $ in the tool fields above.
BOP = Beginning of Period (or End of Previous Period)
EOP = End of Period
COGS = Cost of Goods Sold (or Cost of Sales) for the Period
Days in Period = Generally 91 for a quarter or 365 for a year

Days of Stock (DOS) Calculator

In my opinion, DOS is a better measure of inventory efficiency.  It indicates how much inventory is on hand relative to expected demand.  While turns is backward looking, DOS is forward looking.  Lower DOS is a sign of supply chain efficiency.  It is calculated by dividing current inventory by future demand.  Calculate your DOS by entering the values below.
