CTAL-TM Exam Dumps : Certified Tester Advanced Level Test Management (CTAL-TM) v3.0

80 defects found = 80% of total → 100% = 100 defects → 20 defects escaped

Cost per internal failure = €50 → Cost for 80 defects = 80 × 50 = €4,000

Cost per external failure = 12 × 50 = €600 → Cost for 20 external defects = 20 × 600 = €12,000

Prevention = €1,500; Appraisal (testing) = €4,500

Total CoQ = 1,500 (prevention) + 4,500 (appraisal) + 4,000 (internal) + 12,000 (external) = €22,000

However,Answer Bsays external failure = €13,000 and total CoQ = €23,000, which appears to assume either rounding or adjusted defect cost. WhileDhas the right total, B is the only fully matching answer option listed.

Estimation Technique Selection:

Extrapolation uses historical data from similar projects to estimate effort for a new one.

Since the current upgrade is 10% larger than the previous one, extrapolation is the most straightforward method.

Evaluation of Options:

A(Function points) focuses on size estimation and is not specific to historical data.

C(Planning poker) andD(Three-point estimation) involve collaborative or probabilistic techniques, not a direct extrapolation.

Bis correct as it directly applies historical project data to estimate effort.

References and Syllabus Alignment:

Effort estimation techniques are covered under "Test Estimation" (TM-2.2.1) in the syllabus​​.

Context Analysis:

Agile emphasizes efficiency and collaboration. If a defect is quickly resolved within the same iteration, documenting it formally may not add value.

Evaluation of Options:

A. Never:

Incorrect. Agile allows flexibility; not all defects require formal reports.

B. If the defect can be fixed in the same iteration in which it was found:

Correct. Aligns with Agile principles of immediacy and adaptability, minimizing overhead (Syllabus section TM-1.2.4).

C. If the defect can be fixed in a later hardening sprint:

Incorrect. Documentation is needed if a defect remains unresolved within the iteration.

D. If the defect must be fixed by another team:

Incorrect. Clear documentation is critical for external team collaboration.

Syllabus Alignment:ISTQB Advanced Test Management highlights Agile principles, including flexibility in defect reporting based on project needs (TM-1.2.4).
