Final answer:
Quality issues include faults, failures, and errors. These represent inherent flaws, system malfunctions, and incorrect human actions respectively, all of which engineers must consider when evaluating product quality.
Step-by-step explanation:
Quality issues in engineering and production environments include faults, failures, and errors.
- Fault: An inherent flaw in a component or system that may cause it to malfunction.
- Failure: The event in which a system or component does not perform its required function within specified limits.
- Error: A human action that produces an incorrect result, often leading to faults or failures.
In assessing quality, it's important to consider all aspects, including whether prototypes were tested adequately, the presence of irregularities in the object being measured, and any other factors that affect the outcome which are highly dependent on the situation (e.g., temperature ranges for materials). The engineers pay close attention to these attributes when evaluating the quality of a product design. In summary, quality issues encompass all of the above: faults, failures, and errors.
