4. Managers need to be able to run reports in Salesforce to see daily and monthly order volumes and fulfillment timelines.
5. The legacy system is hosted on premise and is currently connected to the Enterprise Service Bus (ESB). The ESB is flexible enough to provide any methods and connection types needed by salesforce team.
6. There are 1000 sales reps. Each user processes/creates on average 15 orders per shift. Most of the orders contain 20-30 line items.
