The absolute value of the forecast error is calculated as the average of the absolute differences between forecasted and actual demand. Calculating each period: |30-31| + |25-31| + |28-26| + |25-20| = 1 + 6 + 2 + 5 = 14. Therefore, the absolute value of the forecast error is 14.

When a previously reliable supplier starts delivering flawed parts, the first step should be to ex-plore possible root causes. This approach helps in identifying any recent changes in the supplier's production processes, materials, or workforce that might be contributing to the quality issues. By understanding the root cause, the supply manager can work with the supplier to implement correc-tive actions, ensuring long-term solutions rather than temporary fixes. This collaborative approach also maintains a good relationship with the supplier and encourages continuous improvement. References:
