Use Cases Atm System

A use case defines the interactions between external actors and the system under consideration to accomplish a goal. Actors must be able to make decisions, but need not be human: An actor might be a person, a company or organization, a computer program, or a computer system, hardware, software, or both. Actors are always stakeholders, but many stakeholders are not actors, since they never interact directly with the system, even though they have the right to care how the system behaves. For example, the owner of a system, the company’s board of directors, and regulatory bodies such as internal revenue service and the department of insurance…could all be stakeholders but are unlikely to be actors.
Similarly, a person using a system may be represented as different actors because he is playing different roles. For example, user “Hailu” could be playing the role of a customer when using an Automated Teller Machine to withdraw cash from his own account, or playing the role of a Bank Teller when using the system to restock the cash drawer on behalf of the Bank. A use case document is a written guide used in product development. When your company is developing a new product or service, the product developers must know not only the technical characteristics of the product they are developing, but also how the product will be used.
