This activity is the first project activity in the process.
The main project inputs are the test objectives and the SUT information, which may be founded in the Performance Testing Requirements Specification.
After extracting this information, there are already subsidies for the creation of Performance Testing Design.
This initial document may contain some preliminary design information, evolved from the test specifications, such as the intended approach, resource allocation, strategies, etc.
However, the test project is still immature at this stage, so there is no need for a detailed project detail at this moment.
