Options might be available to you, e.g. jump in a car to get away or there is an underground shelter right next to you. Knowing the weather forecast or predicting the weather patterns mean not being in that situation in the first place. More importantly, the right system can examine all the possibilities in sub-seconds and tell you the best way. That is to get into the shelter. To be able to know all the options, one needs an accurate model of the supply chain. Accurate means complete. S&OP models are very rough models and do not know all the options and therefore human intervention is needed. Combined with S&OE, the model becomes accurate and complete but it still lacks intelligence.
As explained above having just visibility is not enough. If a supplier is late and the entire assembly line is waiting for the goods arrival, a decision must be made in minutes if not seconds. If a large order comes in or there is a sudden surge in demand for a number of products, then the number of scenarios increases exponentially. Factors to consider are mix of products to be planned, which suppliers would be best to deploy, what substitute materials and equipment or subcontractors can be used, which clients need to be prioritized and many others.
