CTC - Certified Test Conductor Test Configuration Management Questions and Answers 1 — Questions and Answers
Question 1: A post-test review reveals that a critical power supply used during a qualification test had an expired calibration certificate. As the Test Conductor, what is the most significant implication of this configuration management lapse?
- An anomaly report must be filed against the calibration lab.
- The validity of the collected test data is now questionable. (Correct answer)
- The test schedule will be delayed until the unit is recalibrated.
- The power supply must be immediately removed from service.
Correct answer: The validity of the collected test data is now questionable.
The primary purpose of calibration is to ensure that test and measurement equipment provides accurate and reliable data. Using out-of-calibration equipment means the measurements taken cannot be trusted, which directly invalidates the results and integrity of the completed test.
Question 2: What is the primary function of a "configuration baseline" in test configuration management?
- To list all personnel authorized to be in the control room.
- To provide the initial draft of the test plan for early review.
- To establish a formal, agreed-upon definition of the test setup that serves as the basis for all subsequent test activities and changes. (Correct answer)
- To archive all data and reports after a test is complete.
Correct answer: To establish a formal, agreed-upon definition of the test setup that serves as the basis for all subsequent test activities and changes.
A configuration baseline is a formally approved and documented set of specifications for a system at a specific point in time. In testing, it defines the exact state of the test article, test equipment, software, and procedures against which the test will be conducted and all future changes will be measured and controlled.
Question 3: A Test Conductor is preparing for a formal qualification test of an aerospace flight controller. Which of the following elements is MOST critical to be placed under formal configuration control and documented in the test procedure?
- The brand of multimeter used for spot checks.
- The personal laptops used by engineers for taking notes.
- The specific version and checksum of the flight software loaded onto the controller. (Correct answer)
- The time of day the test is scheduled to begin.
Correct answer: The specific version and checksum of the flight software loaded onto the controller.
The version of the software being tested is a fundamental part of the test configuration baseline. Testing the wrong version of software would make the results inapplicable to the intended qualified item. Therefore, its version number, and often a checksum to verify its integrity, must be formally identified, controlled, and recorded.
Question 4: During a pre-test briefing, a software developer states they applied a "quick, un-versioned patch" to the ground control software. As the Test Conductor, what is the most appropriate action from a configuration management standpoint?
- Halt the test and require the change to be formally documented, approved, and released as a new, controlled version. (Correct answer)
- Thank the developer for their proactiveness and proceed with the test, making a note in the log.
- Proceed with the test but have the developer stand by in case the patch causes issues.
- Ask the developer to email the details of the patch to the test team for their awareness.
Correct answer: Halt the test and require the change to be formally documented, approved, and released as a new, controlled version.
Introducing an undocumented, unapproved change violates the core principle of configuration control. The Test Conductor's responsibility is to ensure the test is run on a known, approved baseline. The proper procedure is to submit the change through a formal process, which includes review, approval (often by a Configuration Control Board), and the release of a new, version-controlled build.
Question 5: In the context of a formal test program, what is the primary purpose of a Test Readiness Review (TRR) as it relates to test configuration management?
- To approve the test budget and secure final funding.
- To formally verify that the test article, facilities, and procedures are in the correct, approved configuration for testing. (Correct answer)
- To train the test team on emergency shutdown procedures.
- To conduct a final review of the preliminary test data.
Correct answer: To formally verify that the test article, facilities, and procedures are in the correct, approved configuration for testing.
A Test Readiness Review (TRR) is a critical gate review to ensure that all elements of the test are in place. From a configuration management standpoint, this includes confirming that the test article is in the proper build configuration, the test procedures are the correct approved versions, all support equipment is calibrated and functional, and personnel are certified and ready.
Question 6: Which of the following activities is a core part of Configuration Status Accounting?
- Approving or rejecting proposed changes to the test procedure.
- Conducting a physical audit to ensure the test setup matches the documentation.
- Identifying the specific software versions and hardware components that will be part of the test.
- Recording and reporting the current status of configuration items and the implementation of approved changes. (Correct answer)
Correct answer: Recording and reporting the current status of configuration items and the implementation of approved changes.
Configuration Status Accounting is the process of recording and reporting information needed to manage the configuration effectively. This includes listing the current approved configuration documentation, the status of proposed changes, and the implementation status of those approved changes, providing visibility into the state of the system.
