CTAL-TM Reviews Questions

Creating a cross-functional team to address the remaining risks is the best option, as it actively involves various stakeholders in the mitigation process. This approach allows for diverse perspectives and expertise to be applied to reduce both the likelihood of the risks occurring and their potential impact, without incurring excessive costs or ignoring the risks altogether.

An iterative/incremental lifecycle model is a type of software development lifecycle that divides the project into smaller iterations or increments, each delivering a part of the functionality and undergoing its own planning, analysis, design, implementation, and testing phases1. This model is suitable for projects that have aggressive schedules, unclear requirements, new technologies, distributed teams, and high quality expectations, as it allows for early feedback, risk reduction, parallel development, frequent delivery, and continuous improvement2. Therefore, option B is the correct answer. Option A is incorrect because a spiral model is a type of iterative/incremental model that adds risk analysis and prototyping activities to each iteration3. While this model can also handle unclear requirements, new technologies, and high quality expectations, it may not be the best choice for projects that have aggressive schedules and distributed teams, as it requires more time andcommunication for risk assessment and prototyping4. Option C is incorrect because a V-model is a type of sequential model that maps each development phase to a corresponding testing phase in a V-shaped diagram5. This model is suitable for projects that have clear and stable requirements, well-known technologies, co-located teams, and moderate quality expectations, as it allows for early verification, traceability, and defect prevention. However, this model may not be the best choice for projects that have aggressive schedules, unclear requirements, new technologies, distributed teams, and high quality expectations, as it does not allow for early feedback, risk reduction, parallel development, frequent delivery, and continuous improvement. Option D is incorrect because a waterfall model is a type of sequential model that follows a linear sequence of phases from requirements to deployment. This model is suitable for projects that have simple and fixed requirements, well-known technologies, co-located teams, and low quality expectations, as it allows for easy planning, management, and documentation. However, this model may not be the best choice for projects that have aggressive schedules, unclear requirements, new technologies, distributed teams, and high quality expectations, as it does not allow for early feedback, risk reduction, parallel development, frequent delivery,and continuous improvement. References: 1: ISTQB Glossary, Iterative/incremental lifecycle model 2: ISTQB Advanced Level Test Manager Syllabus, Section 1.2.1 3: ISTQB Glossary, Spiral model 4: ISTQB Advanced Level Test Manager Syllabus, Section 1.2.1 5: ISTQB Glossary, V-model : ISTQB Advanced Level Test Manager Syllabus, Section 1.2.1 : ISTQB Advanced Level Test Manager Syllabus, Section 1.2.1 : ISTQB Glossary, Waterfall model : ISTQB Advanced Level Test Manager Syllabus, Section 1.2.1 : ISTQB Advanced Level Test Manager Syllabus, Section 1.2.1

According to the ISTQB glossary:

The IDEAL model comprises five phases:Initiating, Diagnosing, Establishing, Acting, and Learning.

“Acting” includes piloting and implementing improvements (e.g. trialing highest-priority improvements).

“Learning” includes evaluating the success and capturing lessons learned (e.g. checking if benefits were achieved).Therefore, C (trial highest-priority improvements) belongs to the Acting phase, and E (benefits check) aligns with Learning.
