From the outside, customers interacting with a company perceive the business as a single entity, despite often interacting with a variety of employees in different roles and departments. CRM is a combination of policies, processes, and strategies implemented by a company that unify its customer interaction and provides a mechanism for tracking customer information.

CRM includes many aspects which relate directly to one another:

• Front office operations — Direct interaction with customers, e.g. face to face meetings, phone calls, e-mail, online services etc.
• Back office operations — Operations that ultimately affect the activities of the front office (e.g., billing, maintenance, planning, marketing, advertising, finance, manufacturing, etc.)
• Business relationships — Interaction with other companies and partners, such as suppliers/vendors and retail outlets/distributors, industry networks (lobbying groups, trade associations). This external network supports front and back office activities.
• Analysis — Key CRM data can be analyzed in order to plan target-marketing campaigns, conceive business strategies, and judge the success of CRM activities (e.g., market share, number and types of customers, revenue, profitability, etc.).
