Supply buffer management includes the use of various buffers to manage the volatility in demand. These include inventory buffers and capacity buffers. If you have a high enough stock of inventory, all fluctuations in demand are absorbed within the inventory. This was the traditional approach maintained by companies wherein sufficient stock was built ahead of time.
But, building up high inventory levels takes up supply chain resources, cost and time, and is not feasible in today's environment. The situation becomes even more complex in cases where products have very short lifecycles and there are high obsolescence costs such as in the High Tech industry. In such cases, maintaining high inventory levels can be disastrous for companies. While maintaining high levels of inventory can be expensive and retaining low inventory levels can negatively impact customer service, a middle ground can be found by building carefully planned inventory levels.
This right balance of planned inventory buffers can be designed to cushion most of the shocks from the volatility in demand. The challenge is determining the right level of the supply chain at which safety stock should be maintained, the right locations at which to maintain inventory and the right quantities. By planning these effectively, companies can significantly improve their ability to respond to volatile demand in a cost-effective way. Several companies are embarking on implementations of inventory optimization solutions which analyze a company's demand patterns and supply chain processes and determine the appropriate inventory levels to maintain across various locations of the supply chain.
Lean manufacturing initiatives have been proven to help companies reduce cycle times by eliminating non-value added activities in the supply chain. Use of constraint based planning approaches, which are embedded in most advanced planning solutions, can help companies identify and resolve bottlenecks ahead of time thus helping reduce cycle time. Such a shift enables a company to be more flexible and better respond to changes in demand. Companies across several industries are already evaluating such a shift as part of their overall supply chain strategy.
However, a shift from MTS to ATO strategy may not be the right strategy for all companies. The decision to implement a postponement strategy should be based on careful consideration of a company's supply chain characteristics such as commonality of sub-assembly products, length of production cycle times, customer lead time expectations etc. While such a strategy shift can significantly improve a supply chain's performance in its ability to respond to changes in demand faster, implementation costs could be a deterrent. Shifting a company's strategy from Make-to-Stock to Assemble-to-Order can be very costly to implement since it requires changes to supply chain activities , processes and enabling systems. Visibility to supply chain events can be transferred to all supply chain partners, thus helping them all work together to achieve the goals of efficiently meeting customer demand.
In conclusion, while demand volatility is a reality faced by companies across many industries, by employing the right supply chain strategies companies can efficiently handle volatile demand. Key supply chain strategies required to manage volatile demand are outlined in this article.
