Many companies believe that once a forecast is created success will follow throughout the product life cycle. However, this is not the case.
Reality: To create the most accurate forecasts, planners must employ the forecasting methods that best serve the unique dynamics of their business at a specific moment in time. Forecasting needs to be flexible and change with shifts in demand patterns.
Top performing organizations employ multiple forecasting methods that best serve the unique dynamics of their business at a specific moment in time. Advanced demand planning and forecasting solutions automate many of the functions required to select, model and generate forecasts. This removes the burden of manually switching models and accelerates sensitivity as market conditions evolve. For example, a modified Holt-Winters decomposition model with best-fit analysis can generate forecasts based on demand history that incorporates trends and seasonal information which may later be refined based on demand sensing and POS data. This capability to automatically change forecasting methods is an essential feature of a comprehensive forecasting solution.
No company or their supply chain is the same. Spreadsheets and homegrown solutions are the way of the past and cannot scale to compete with best-in-class forecasting solutions. Today, companies must combine available historical data, forward-looking market knowledge and multiple forecasting techniques to build the foundation of a forecast the business can trust. Through artificial intelligence, we can automatically adjust methods during a product’s life cycle to maintain maximum accuracy from product launch through end-of-life. A single forecast is unable to keep up with these rapid changes and will often lead to either too little or too much inventory.
Companies must move beyond simple forecasts for all items in their portfolio and draw from a range of methods to create a demand plan that best fits each forecasted item at every stage of its life cycle.
