Is the statement "when constructing test plans, the skilled labor must decide what features to test and how to evaluate performance" true or false?

The statement is true because constructing test plans is a critical aspect of the testing process in engineering and product development. Skilled labor, such as engineers and testers, play a vital role in determining the features that need to be tested. This involves a comprehensive understanding of the product's design, functionality, and intended use, allowing them to identify crucial aspects that ensure the product meets quality standards.

Additionally, skilled labor must establish the criteria for evaluating performance. This includes defining benchmarks, methodologies, and metrics that will effectively assess how well a product functions and whether it meets the required specifications and user expectations. A well-structured test plan not only enhances the reliability of the testing process but also ensures that any potential issues are identified and addressed before the product reaches the market.

Therefore, the importance of carefully deciding what features to test and how to measure performance is central to successful engineering practices, making the statement accurate in the context of both product and software testing.
