If you truly value time, money, and return on your investment, you will run a cost-benefit analysis (CBA). Instead of blindly jumping into an ERP system, compare the cost of revamping your existing system first. A CBA is one of the best ways to weigh the risks of infrastructure enhancements and operational costs.
Performing a CBA will also help you understand how many systems the ERP system will replace. ERP systems can track business resources like inventory and raw materials, overhead, and commitments like employee payroll, purchase orders, and custom orders. This sounds comprehensive, but does your company actually need these capabilities at the moment?
