Oliver Wight’s White Paper, Demand Review: Tell the Story, by Colleen “Coco” Crum, advises clients implementing Integrated Business Planning (Advanced S&OP) to understand and adopt a true aggregate planning process and redesign their Demand Review. Crum presents a case study about a company attempting to implement IBP based on a 24-month planning horizon, while really only planning for the next quarter, and she argues that the demand planners simply allowed the statistical forecast to compute the item-level projections but failed to take into account that brand and product plans might change over time.
