Just What Is It That SCM Software Does?

It's worth mentioning that the old adage about systems only being as good as the information that they contain applies doubly to supply chain management software. If the information entered into a demand forecasting application is not accurate, then you will get an inaccurate forecast. Similarly, if employees bypass the supply chain systems and try to manage things manually (using the fax machine or spreadsheets), then even the most expensive systems will provide an incomplete picture of what is happening in a company's supply chain.
