When is it time to Implement a Forecast Improvement Process?

Supply chain optimization should be a continuous and fluid process. Current business processes and strategies should be evaluated frequently to determine areas of improvement. In our post, titled “Three Steps to Better a Better Statistical Forecast,” we explained this process in detail. The three steps are; simulate, measure, and refine.

The first step in improving your current statistical forecast starts when evaluating your current forecast strategy. At this stage of the process, it helps to create multiple what-if scenarios. What-if scenario simulation presents a better way to create an improved planning process by allowing planners to anticipate all possible scenarios that could affect their forecast. Simulating different scenarios based on possible environmental and market changes improves the forecasting process to make businesses better prepared for unexpected changes.
