Object-oriented applications frequently rely on Use Cases to describe the business processes of a software application. Since use cases consist of the strategic goals and scenarios that provide value to a business domain, they can also provide insight into an application’s complexity. Deriving a reliable estimate of the size and effort an application needs, is possible by examining the actors and scenarios of a use case. Use Case Points is a project estimation method that employs a project’s use cases to produce an accurate estimate of a project’s size and effort.
