  2. The general public.

  3. Users already familiar with the application.

  4. Users unfamiliar with the application.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

To choose the correct option, the user needs to understand the purpose and importance of user testing during the development cycle of any software application. User testing is necessary to ensure that the application meets the user's requirements and expectations and identifies any bugs that need to be fixed before release.

Option A is incorrect since selecting the most experienced technical personnel may not provide the necessary feedback for the application's usability and accessibility to non-technical users.

Option B is also incorrect because while the general public may provide a wide range of feedback, they may not be the ideal target audience for the application.

Option C may provide valuable feedback, but it may not be sufficient in identifying issues that may arise with new users.

Option D is the correct answer since users unfamiliar with the application can provide valuable feedback on the application's usability, accessibility, and overall user experience.

Therefore, the correct answer is:

The Answer is: D. Users unfamiliar with the application.

Multiple choice six-sigma green-belt

A Correct answer
Explanation

Simulation models process behavior to test solutions before full implementation, reducing risk in the Improve phase. CAP addresses changes, Cost Benefit Analysis evaluates financial impact, and FMEA identifies failure modes - none are primarily testing tools.

Multiple choice six-sigma green-belt
  1. Defect

  2. Defective

  3. Defect Opportunity

  4. Defect Variation

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

To solve this question, the user needs to understand the concept of quality control and the terminology used in quality management.

The answer to this question is C. Defect Opportunity.

Explanation:

A defect is a nonconformity, or failure to meet a customer requirement. A defective item is one that contains one or more defects.

A defect opportunity is any event or occurrence during a production or service process that provides a chance for a defect to occur. A single item or service can have multiple defect opportunities.

Defect variation refers to the differences in quality among the output of a process.

Therefore, option A is incorrect because it refers to a nonconformity or failure to meet a customer requirement, but does not account for the number of opportunities for a defect to occur.

Option B is incorrect because it refers to an item that contains one or more defects, but does not account for the number of opportunities for a defect to occur.

Option D is incorrect because it refers to the differences in quality among the output of a process, but does not account for the number of opportunities for a defect to occur.

The Answer is: C. Defect Opportunity

  1. Testing expertise

  2. Buy-in for possible solution

  3. Risk of implementation

  4. Cost-benefit analysis

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Testing solutions in the Improve phase builds stakeholder confidence and support for the recommended approach. Pilot tests demonstrate feasibility and generate buy-in before full implementation. Testing expertise increases, risk decreases (not increases), and cost-benefit analysis happens before testing.

  1. Failure Measure & Efficiency Analysis

  2. Failure Mode & Effect Analysis

  3. Frequently Monitored Effect Analysis

  4. Function Measure Effective Analysis

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

FMEA stands for Failure Mode and Effects Analysis. It is a systematic method used to identify potential failure modes in a process, product, or system, assess their severity and likelihood, and prioritize actions to prevent or mitigate them. The full name exactly matches option B, making it the correct answer.

Multiple choice six-sigma green-belt
  1. Listing all the failuremodes

  2. Refining the solution based on failuremodes

  3. Minimizing the measurement error

  4. Control Impact Analysis

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

FMEA is used during solution development and implementation to identify potential failure modes and refine the solution accordingly. By analyzing how a solution might fail (failure modes) and what the effects would be, teams can proactively modify the design or process to prevent those failures. This preventive approach ensures solutions are robust before full deployment, making 'Refining the solution based on failuremodes' the primary use.

  4. Pareto analysis

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Failure Mode and Effects Analysis (FMEA) systematically identifies all potential failure modes, their causes, and effects on the system. It prioritizes risks by RPN (Risk Priority Number). PDCA is improvement cycle, Fishbone diagrams identify root causes, and Pareto analysis prioritizes frequency of issues.
