Variation in upstream requirements can be significantly reduced by increasing demand visibility. When all partners in the supply chain have clear and accurate information about actual demand, they can better align their production schedules and inventory levels, thus reducing the variability and uncertainty that lead to inefficiencies. Improved demand visibility helps in forecasting accuracy, better planning, and more responsive supply chain operations. Increasing production capacity, product features, or safety stock does not address the root cause of demand variability; instead, they are reactive measures that do not improve upstream stability.
