Test Effort Estimation Using Use Case Points (UCP)

Key Points

Presentation Abstract

This paper presents a new approach based on Use Case Points [UCP] as a fundamental project effort-estimation measure. The use of UCP on projects is still in its infancy and it is not a very widely known measure. However, from preliminary applications on our web-based projects, we conjecture that this could in fact be more reliable than FP.

The caveat here is that the V-model must be in use and use case generation must start becoming available right at the requirements gathering phase. The acceptance test plan is then prepared with the use cases from the requirement documents as input.

It is known that a use case to test case mapping is possible. This means that the UCP figure for development can be indirectly used to provide a figure for the number of test cases. Using organizational test execution time metrics it is now possible to arrive at a figure for the total test effort.
