The customer relationship management system is an enterprise system, which means that it spans multiple departments. Virtually all departments within a corporation have at least some indirect access to customers, or customer information; the goal of CRM is to collect that information in a central repository, analyze it, and make it available to all departments. For example, a company's call center may have a "screen pop," a small application that is connected to the phone system. This application, which is a type of CRM, automatically senses who is calling, and by the time the agent answers the phone, produces a screen on the computer that lists important information about the caller, such as what they have purchased in the past, what they are likely to buy in the future, and what products the company may have available that would go well with what the customer has already bought. This "screen pop" is made up of several bits of information from different databases; it may draw on information from the accounting department to show the agent what their current balance may be; it may draw on information from the sales department to show what has been purchased recently, and it may draw on information from the credit department to show the agent what terms can be offered
