it may seem obvious but sales people are more effective when thay have a clear target, and the more detailed you can be, the better. Depending on your business, try to give your team details like the customer's name, address, and phone number. If you don't have this information, then give them descriptive details on the types of customers they should go after. For example, if you're selling medical equipment to hospitals, your direction might sound like this: call on purchasing managers in hospitals with more than 100 beds within these zip codes.
