Having S&OP and S&OE as two separate systems does not make sense, it is redundant and costly. Having two systems implies two disjoint systems that do not understand each other’s data model.
Thanks to Covid-19 almost every supply chain is being re-examined to become more resilient. But there is only so much you can do! There are external factors over which you have no control such as demand changes, up or down, tariffs or dock worker strikes!
Why, because S&OE has a more accurate model of the world & can figure out all the alternatives and make a quick and optimal decision that can be followed.
The concept of supply chain digital twin has become very popular in recent years. It is essentially a digital model of your supply chain intended to be the foundation for companies to plan and operate their supply chain digitally and autonomously.
Many companies have or are in process of implementing S&OP solutions aiming to digitalize their supply chains. S&OP is essentially a high level rough cut and long-term model of the supply chain.
