Topic 12, Scenario 7 "Test Estimation"
You have been contracted to manage the acceptance testing of a new computer-based reservation system for a travel agency. You have provided an approximate budget estimate for the testing project based on previous experience with similar sized projects. However, the management of the parent company of the travel agency will not commit to the budget until detailed cost estimates are provided.
The reservation system is being developed by a third party However, detailed specifications of the software are available, as well as an estimate of the total effort that will be spent in developing the software. The software is to be delivered in four increments, and the functionality to be delivered in each increment has already been agreed on.

The requirement phase serves multiple purposes. It aims to understand user needs, freeze the requirements to provide a stable basis for development, and define the scope of testing. These activities ensure that the project has a clear direction, and the testing efforts are aligned with the defined requirements. The ISTQB CTFL Syllabus outlines that a thorough requirement phase is essential for the success of subsequent phases in the software development lifecycle.
