Key Supply Chain Planning Elements
This is the key business planning element for marketing and sales leaders to interface with their internally-focused colleagues from finance and the supply chain. It is through this step, or series of steps, that the business can get input from all parties regarding product promotions, seasonal customer demand, innovation performance expectations, and a proper understanding of material requirements and capacity utilization at the factories.
In essence, this planning step puts the entire business on the same page regarding the coordination of supply assets and capabilities in order to meet customer demand requirements for the tactical (60-90 day horizon) and longer term (12 to 24 months). This process, typically monthly, is supplemented by a more operational counterpart, the weekly operations process, which focuses on the same issues at the operational, or zero to 60-day level.
Potential pitfalls and problems can materialize when hidden agendas fail to unmask complications. For example, the sales group may elect to underestimate upcoming demand in an attempt to “overdeliver” their revenue expectations, or they may simply not understand market or customer conditions. Businesses will often view this ploy as a good problem, but the fact is that rush shipments, unplanned factory overtime, irritated customers and value-robbing waste inevitably cut into bottom line profits.
A well run S&OP process can also prevent the business from overselling its installed capacity to produce finished goods. By understanding both the demand and supply details of the business, it can better control both revenue and cost profiles.
This is an area where we see more confusion and higher levels of inaccuracy than in any other. If there is a “magic bullet” to improve overall supply chain performance, this is it. Why? Because demand forecast accuracy equates to:
- Accuracy of inbound materials management;
- Accuracy in manufacturing network utilization;
- Accuracy of inventory management and working capital;
- Accuracy in customer order fulfillment;
which all leads to:
- Better financial management, cost control and less organizational waste. This is an area where working closely with customers and suppliers can provide the supply chain with the opportunity to drive incremental value to a company. Think about the knock-on effects of poor demand planning:
- Supply management needs to generate ongoing contingency plans for the purchase and delivery of materials to their factory networks, resulting in waste of time, cash and sub-optimal MRP system performance;
- Incorrect product mix in the wrong region, resulting in wasteful inter-facility and customer delivery freight costs;
- Ultimately leading to inaccurate supply planning and excessive levels of safety stock—again more waste of inventory, warehouse space and cash in the form of working capital;
- And finally, but of utmost importance, customer satisfaction problems.
Bringing together all of the downstream elements of supply chain performance is the supply plan. It is here that companies can generate the optimum performance from their manufacturing, transportation and inventory management systems. Given that the production network, whether an internal factory network or third-party manufacturers, is the source of conversion cost expenses, greater accuracy in the supply plan (driven of course by an accurate demand plan) invariably leads to fewer line changeovers, (with the associated reduced downtime), longer run sequences (and the associated lower waste), higher asset utilization rates, more accurate inventory quantities, and better on-time deliveries to customers. Oftentimes, accuracy in the overall planning process allows a company to reduce capital expenditures related to capacity requirements, since better utilization of installed capacity equates to a built in increase in system capacity.
The elimination of wasteful downtime, reduction of safety stock levels, coordination of material flow and inbound freight, knowledge of customer requirements, and the direction of marketing promotions all yield to a classic definition of lean operations and manufacturing. This reduction of waste in all its forms provides the foundation for better margins and higher profitability.
While not as sexy as product innovation, branding exercises, promotions, or packaging design, dedication to excellent planning systems helps to drive everything from purchasing efficiency to superior customer service. Powerful planning processes provide the essential elements for business success through material management, lean operations, waste reduction and working capital optimization.
