Field Study: Influence of Different Specification Formats on the Use Case Point Method

The Use Case Point method (UCP method) has already been described in detail in 1. It  is a  top-down estimation method  that classifies  the  functional  requirements of  the specification  into countable units  (use cases),  to which points are assigned  (use case points) according  to  their estimated complexity. The estimated project effort  is  then proportional to these use case points.
