What is a primary benefit of reducing human error in testing?

• A. It decreases the overall cost of testing
• B. It increases the complexity of test procedures
• C. It improves the accuracy and reliability of test results
• D. It guarantees perfect test outcomes

Answer: (C)

Improving the accuracy and reliability of test results is a key benefit of reducing human error in testing. Human error can introduce variability and mistakes in data collection, procedure execution, and result analysis, which subsequently compromise the integrity of the testing process. When human error is minimized, the consistency and precision of the results are enhanced, leading to more trustworthy conclusions and better decision-making based on those results.

In testing and evaluation processes, achieving high reliability means that results can be replicated under similar conditions, and high accuracy means that the results closely reflect the true values or performance characteristics being measured. By focusing on reducing the chances for human error, organizations can ensure that their test outcomes are a true representation of the system, process, or product being evaluated.

While it might seem that decreasing human error could lead to reduced costs, increase efficiency, or possibly produce favorable outcomes, those factors are secondary to the fundamental aim of achieving reliable and accurate results that inform subsequent decisions and actions. Therefore, emphasizing the accuracy and reliability arising from minimized human errors is essential in the context of effective testing and evaluation practices.
