What is the relationship between ERP, CRM and SCM?
Many SCM applications are reliant upon the kind of information that is stored inside enterprise resource planning (ERP) software and, in some cases, to some customer relationship management (CRM) packages.
Theoretically a company could assemble the information it needs to feed the SCM applications from legacy systems (for most companies this means Excel spreadsheets spread out all over the place), but it can be nightmarish to try to get that information flowing on a fast, reliable basis from all the areas of the company.
ERP is the battering ram that integrates all that information in a single application, and SCM applications benefit from having a single major source to go to for up-to-date information.
Most CIOs who have tried to install SCM applications say they are glad they did ERP first. They call the ERP projects "putting your information house in order." Of course, ERP is expensive and difficult, so you may want to explore ways to feed your SCM applications the information they need without doing ERP first.
These days, most ERP vendors have SCM modules, so doing an ERP project may be a way to kill two birds with one stone. In addition, the rise and importance of CRM systems inside companies today puts even more pressure on a company to integrate all of its enterprisewide software packages. Companies will need to decide if these products meet their needs or if they need a more specialized system.
Applications that simply automate the logistics aspects of SCM are less dependent upon gathering information from around the company, so they tend to be independent of the ERP decision. But chances are, companies will need to have these applications communicate with ERP in some fashion.
It's important to pay attention to the software's ability to integrate with the Internet and with ERP applications because the Internet will drive demand for integrated information. For example, if a company wants to build a private website for communicating with their customers and suppliers, the company will want to pull information from ERP and supply chain applications together to present updated information about orders, payments, manufacturing status and delivery.
