Select the BEST description of quality metrics.

Quality metrics are specific measurements or indicators that are used to assess the quality of a product, process, or project. They provide a quantitative or qualitative basis for evaluating whether the desired level of quality is being achieved. By establishing what should be measured and defining acceptable measurements, quality metrics help monitor and control quality throughout the project lifecycle.

The other answer choices are not as accurate:
- A tool to ensure that quality-related steps are performed: This is a description of quality assurance, not quality metrics.
- Detailed steps for determining waste and non-value-added activities within the processes: This is a description of process mapping, not quality metrics.
- Ensures that the concepts, designs, and tests selected at the beginning of the project are correct: This is a description of validation, not quality metrics.
Quality metrics can be used in a wide variety of industries and applications. For example, a software development company might use quality metrics to track the number of bugs found in their software, while a manufacturing company might use quality metrics to track the percentage of products that meet their quality standards.
