What problem of manual system?

Accuracy, Ability to reliably update data and take action on trigger events Time it takes to manage the data time it takes to retrieve the data, make updates, ect. Ability to share the data. and the time it takes to share the data. As an example someone in another office needs to know something about a customer. Now they would need to call you, wastes everybodies time. The person should be able to lookup the data in the amount of time it takes to dial the phone.
