ISTQB CTAL-TM Exam With Confidence Using Practice Dumps

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).

A distributed model for testing is a testing model that involves testers working in different locations, time zones, or organizations, such as onshore, offshore, or nearshore1. The primary factor that you should consider with this model is the alignment of methodologies, which means that the testers follow the same or compatible testing processes, standards, tools, and techniques, regardless of their location, time zone, or organization2. The alignment of methodologies can help to ensure the consistency, quality, and efficiency of the testing activities, as well as to facilitate the communication, coordination, and collaboration among the testers3. Therefore, option A is the correct answer. Option B is incorrect because co-location of test team is not a factor that you should consider with a distributed model for testing, but rather a factor that is contrary to a distributed model for testing. Co-location of test team means that the testers work in the same physical location, which can have some advantages, such as easier communication, faster feedback, and stronger team spirit, but also some disadvantages, such as higher costs, limited resources, and less diversity4. Option C is incorrect because provision of growth opportunities for the individual testers is not a factor that you should consider with a distributed model for testing, but rather a factor that is relevant to any testing model. Provision of growth opportunities for the individual testers means that the testers are given the chance to learn new skills, gain new experiences, and advance their careers, which can have some benefits, such as increased motivation, productivity, and retention of the testers. Option D is incorrect because planned vs. actual hours is not a factor that you should consider with a distributed model for testing, but rather a factor that is relevant to any testing model. Planned vs. actual hours is a testing metric that compares the estimated and the actual effort spent on the testing activities, which can help to measure the accuracy of the test estimation, the efficiency of the test execution, and the variance of the test schedule. References: 1: ISTQB Glossary, Distributed Testing 2: Distributed Testing - Software Testing Fundamentals 3: ISTQB Advanced Level Test Manager Syllabus, Section 3.2.1 4: Co-located vs. Distributed Teams: What’s the Difference? : How to Provide GrowthOpportunities for Employees : Software Testing Metrics: What is, Types & Example
