For which of the following activities would the costs be classified as a cost of detection?

Assume you have some data related to confirmation testing during system testing of a past
project.
In that project 240 bug reports have been opened once, 80 were opened twice, 10 were opened
three times and no bug reports have been opened more than three times.
You estimate that a bug report, which has failed its confirmation test, costs, on average, 3 personhours.
Which of the following statements correctly describe the value of these confirmatory testing
activities based on cost of quality?

Which of the following answers describes a factor that may reduce the effort spent when using
distributed test teams without negatively affecting system quality?

You are the Test Manager on a project following an iterative life-cycle model. The project should
consist of nine iterations of one month duration each. It is planned to develop the most important
features to have a stable core of the application in the first three iterations and to add the
additional features in the last six iterations.
At the beginning of the first iteration, only a draft version of the requirements specification
document for the core features is available. Assume that during each of the first three iterations,
the chosen features are fully completed and unit tested.
Which of the following statements is true in this context?

Which of the following statements, about the test reporting activities for a project adopting an
iterative lifecycle model with very short iterations (e.g. two weeks iterations), is correct?
