Authentic ISTQB Certification Exam CTAL-TM Questions Answers

Context Analysis:

The manager perceives conservative estimates as overly negative. The goal is to balance optimism with realism to satisfy both the team and the manager.

Three-point estimation provides a range of estimates: optimistic, pessimistic, and most likely, addressing the need for a positive yet realistic projection.

Evaluation of Options:

A. Wideband Delphi:

Involves group-based estimation using consensus techniques. While reliable, it does not explicitly offer optimistic vs. realistic estimates.

B. Planning Poker:

Often used in Agile projects, this technique involves relative estimation but does not inherently provide optimistic and pessimistic figures.

C. Three-point estimation:

Correct. Combines optimistic, pessimistic, and realistic estimates to calculate a weighted average. This allows presentation of both realistic and “positive” numbers to the manager.

D. Extrapolation:

Based on past data trends but does not offer a range of estimates or a way to address manager concerns directly.

Syllabus Alignment:The ISTQB syllabus mentions estimation methods like three-point estimation as effective techniques for providing balanced and transparent project timelines (TM-2.2.1).

Analysis of the Situation:

The GPS accuracy and functionality have been confirmed to work correctly as per depth and breadth testing.

Despite this, users experienced severe issues such as walking off a cliff or into a river. These incidents point to usability problems related to user interpretation of the GPS data and system feedback.

Testing Prioritization:

Usabilitytesting evaluates how effectively and safely users interact with the application. Here, it should focus on improving user guidance, error prevention, and alerts.

FunctionalityandPerformanceare not the problem since they passed testing.

Securityis unrelated to the specific reported issues.

References and Syllabus Alignment:

This aligns with usability-focused risk mitigation strategies in the ISTQB Advanced Test Management syllabus under "Test Process" and "Test Techniques" (TM-1.3.4)​​.

Understanding the Agile Context:

Retrospectives aim to identify and implement process improvements collaboratively.

Focusing on solutions, not blame, aligns with Agile principles.

Evaluation of Options:

A. You should attend the retrospective instead of the individual testers:

Incorrect. Retrospectives are team-wide events; excluding testers undermines collaboration.

B. You should do root cause analysis to prove the developers are responsible:

Incorrect. Assigning blame contradicts Agile’s collaborative ethos.

C. You should gather metrics to present to the team regarding all the hours spent testing:

Incorrect. Metrics may provide insights but are insufficient to address process improvement.

D. You should help the team brainstorm ideas on how to improve the testing to eliminate the escapes:

Correct. Encouraging collaborative problem-solving directly addresses the root causes of defects escaping to users.

Syllabus Alignment:

ISTQB highlights retrospectives as opportunities for continuous improvement in Agile projects (TM-1.2.4).
