What is the basic principle of the Wideband Delphi estimation technique?

The project manager decides the estimate without input from testers

Estimates are derived from the cost of the project

Estimates are based solely on the number of test cases

Experts provide estimates independently, then discuss and converge on a consensus

What is a key input testers provide during release planning?

An assessment of whether the product meets the exit criteria

A list of all features planned for the next release

The detailed design of the system architecture

A test manager is defining entry criteria for a new test phase. The team has a history of starting testing before the build is stable, leading to wasted effort. Which entry criterion would best address this issue?

All test cases must be written before testing begins.

The test team must have completed training on the new tool.

The build must pass a smoke test before testing begins.

The test environment must be available 24/7.

A test manager is estimating the effort for testing a new system. The team has historical data from similar projects, including the number of defects found and the effort spent. Which estimation technique would best leverage this historical data?

Use expert judgment based on the test manager's intuition.

Use a three-point estimation with optimistic, most likely, and pessimistic values.

Use a work breakdown structure to list all tasks.

Use metrics-based estimation, such as defect density, to estimate effort.

A tester needs to estimate the effort for testing a new feature. The feature has a well-defined scope and is similar to a feature tested last month. The tester has detailed records of the effort spent on the previous feature. Which estimation technique would be most efficient and accurate?

Use the historical effort data from the similar feature as a baseline and adjust for differences.

Use function point analysis to independently size the feature.

Use a random guess based on the tester's gut feeling.

Use a three-point estimation with a wide range to cover all possibilities.

Part of the Domain 5: Managing the Test Activities domain, which makes up ~20% of our current practice bank. ISTQB does not publish an official question count, but from its 60-minute exam (~25–40 total, ~5–8 in this domain), expect 1–2 from this objective — we provide 34 practice questions to prepare you well beyond it.
