A best practice is to examine the inefficiencies in existing processes to find ways to improve on or significantly simplify the process. For example, manual document intensive processes (such as order entry and billing) create major headaches for workers. These processes require users to manually review documents for approval, enter data from those documents into a back-office system, and then make decisions. Automated order entry systems track customer orders from the time of initial order placement through the completion of those orders; they also perform backorder processing, analysis, invoicing, and billing.
