Supply-Chain Definition Supply Chains are the Totality of processes spanning operations from supplier to end-customer, focused on material, work, human, cash and information flow We use a tool called the Supply Chain Definition Matrix to define the supply-chains within an enterprise The Supply Chain Definition (i/o Matrix) Matrix helps determine the number and size of supply chains Columns: Customers (Output) Rows: Products (Input) The intersection of each column and row if the goods or services flow to the customer is a supply chain 2011 Supply Chain Council.

The Matrix We now place the customer list as column headings repeating until finished And then the products list as row headings repeating until finished For each product that flows to a customer, we put an X in the cell It s that simple.

Supply Chain Prioritization We use a tool called the Supply Chain Prioritization Matrix to order the supply-chains according to relevance Each supply chain can be ranked by a number of features We suggest: size (revenue, volume, and margin), complexity (# SKUs) strategic importance You can also look at them by Cash Consumption Risk Volume variability Etc. 2011 Supply Chain Council.

Supply Chain Strategy We use a tool called the Supply Chain Strategy Matrix to Identify priority strategic features or attributes of supply-chains. Each supply chain strategy is indicated by a collection of ranked features: Reliability On time? Complete? Undamaged?
