How fast are you at turning your cash (sometimes you need to consider from the balance sheet perspective, payment terms, depreciation, inventory and etc.) How businesses finance money? ο· To get it from the bank or the shareholders ο· ο· ο· Financing cost has to be included into the cost of the product to ensure the company profits. (e.g. strategic location of the distributor from the production centre is essential as the nearer it is, the lesser cost incurred from transportation) Payment terms is important for supply chain managers as well as they have to take inconsideration of how they’re going to finance it As a SC Manager you want to keep inventory low while having high inventory turnover (lesser cost for holding inventory, more goods sold, higher INVT) Others - ART = higher the better, this means that customers pay the business very quickly AR = lower the better, less money owed by customers APT = the lower the better, this means that the business is taking longer to pay its supplier allowing them to have more $$ on hand to finance their business NWC = negative NWC is favorable Good SCM 1. Reduce inventory 2. Increase inventory turnover 3. Lengthen payment terms with supplier 4. Shorten the collection of payment from customer Drivers of Supply Chain Performance Logistical Drivers ο· ο· ο· Facilities – Places where inventory is stored, assembled or fabricated Inventory – Raw materials, WIP, finished goods within a supply chain Transportation – Moving inventory from point to point in a supply chain (anything related to the transportation within the supply chain flow) Cross Functional Drivers ο· ο· ο· Information – Data and analysis regarding inventory, transportation, facilities throughout the supply chain (information is sufficient till a point where it incurs more cost than benefits) Sourcing – Functions a firm performs and functions that are outsourced Pricing – Price associated with goods and services provided by a firm to the supply chain Supply Chain Decision-Making Framework Walmart Examples Competitive strategy – reliable, low-cost retailer with large product variety Supply chain strategy – efficient but responsive in terms of product availability Logistical drivers: 1. Facilities – centrally located DCs within a network of stores, increases efficiency 2. Inventory – low level with cross-docking at stores (cross-docking have minimal or no storage time) 3. Transportation – runs own fleet, increases costs but improves responsiveness Cross-functional drivers: 1. Information – large investment for high responsiveness, decrease inventory investment 2. Sourcing – large orders to efficient sources for economies of scale 3. Pricing – “Everyday Low Price” ensures steady customer demand without fluctuation Facilities as a Driver (Logistical Drivers) Role in the Supply Chain - The “where” of the supply chain Manufacturing (factories) or storage (warehouses) Role in the Competitive Strategy - Economies of scale (efficiency priority) Large number of smaller facilities (responsiveness priority) Facilities Places where inventory is stored, assembled or fabricated ο· E.g. production sites, storage sites, warehouses, factories, distribution centres Decisions Roles: level of flexibility ο· Flexible capacity: used for multiple products ο· Dedicated capacity: used for limited products ο· Combination of the two Location ο· Risks in the located area ο· Closer to customer, decentralised ο· Centralised Capacity ο· Large excess capacity ο· Little excess capacity Facility-related -

Supply chain metrics related decisions determine the overall performance of the supply chain 2. These drivers interact with each other to achieve a balance between efficiency and responsiveness of the supply chain 3. Numerous metrics or performance measures are used to gauge the performance of these drivers
