Purpose of the Defect Management Committee (DMC):
The DMC evaluates reported defects to confirm their validity, prioritize them, and create plans for resolution.
It ensures effective coordination between testers, developers, and stakeholders.
Evaluation of Options:
A (Controlling defect report flow) is a subset of validation but not the main purpose.
B is correct because it fully captures the committee's role.
C (Implementing strict guidelines) is procedural, not the DMC's core function.
D (Ensuring developers fix all defects) misrepresents the committee's authority.
Reference and Syllabus Alignment:
This aligns with defect lifecycle management as described in "Defect Management" (TM-2.3.1).

Explanation/Reference:
Explanation:

A model-based testing strategy is a testing strategy that uses models to represent the desired behavior and structure of the system under test, and to derive test cases, test data, test procedures, and test oracles1. A model-based testing strategy requires an activity to select an appropriate quality standard, such as ISO 9126, to be used to guide the testing. A quality standard is a set of criteria, guidelines, or characteristics that define the quality attributes of a software product, such as functionality, reliability, usability, efficiency, maintainability, and portability2. A quality standard can help to define the quality requirements, objectives, and measures for the system under test, and to evaluate the quality of the test results and the test process3. Therefore, option C is the correct answer. Option A is incorrect because conducting a quality risk analysis with all affectedstakeholders is not an activity specific to a model-based testing strategy, but rather a general testing activity that can be applied to any testing strategy. A quality risk analysis is a process of identifying and assessing the quality risks that may affect the system under test, and prioritizing them based on their impact and likelihood4. Option B is incorrect because conducting operational profiling to determine the expected usage of the system is not an activity specific to a model-based testing strategy, but rather an activity related to a usage-based testing strategy. An operational profile is a statistical representation of the relative frequencies of the inputs, operations, and operating conditions of a system in its operational environment. Option D is incorrect because creating the test charters for the exploratory testing sessions is not an activity specific to a model-based testing strategy, but rather an activity related to an exploratory testing strategy. A test charter is a document that defines the scope, objective, and approach of an exploratory testing session. References: 1:

The most likely cause of the traceability breakdown in the testing area is that the testers are not updating the test execution information in the test management system. This is because the test management system is a tool that supports the test process, and it can store and manage the test documentation, such as the requirements, the test conditions, the test cases, and the test results. If the testers do not update the test execution information in the test management system, such as the test cases that are run, the test results that are obtained, and the defects that are found, the traceability between the test cases and the test conditions will be lost or inaccurate. This can affect the test analysis and reporting, and the test coverage measurement.

A test manager must assemble team members that will spark informal cross training among themselves. This means that the team members are willing and able to share their knowledge, skills, and experiences with each other, and learn from each other's feedback and suggestions. This can improve the team's performance, productivity, and quality, as well as foster a collaborative and supportive culture. Cross training can also help the team members to develop new competencies, fill skill gaps, and handle different roles and tasks when needed.
