Resistance to forecast revision creates more turbulence than embracing it.
As the demand patterns evolve in the market, earlier forecasts get out of sync with reality. If we still stick to these prior forecasts, we end up obstructing smooth flow of products through the supply chain. The supplies either flood the pipeline or throttle it.
It is absolutely essential for the forecasts to continually adapt to the market reality of demand. Inventory buffers created using the latest forecast will then ensure a smooth flow through the entire supply chain.
Teams which embrace forecast revisions see a much smoother flow than the teams which resist these revisions and experience turbulence.
