The overall goal of SIOP is to connect the sales side of the business (generating product demand) to the supply side of the business (fulfilling that demand) so that they are continually synchronized.
This planning process enables the sales side to develop a realistic, achievable forecast by knowing what the supply side is capable of producing and in what time frame. Likewise, the supply side knows what sales is trying to achieve and enables them to plan and align their resources to support the anticipated demand. If achieved, this coordination will in turn facilitate excellent service and proactive communications – internally among departments, and externally with both customers and suppliers.
