Exam DA0-001 topic 1 question 84 discussion

B. Observation By directly observing the product in use or during the production process, analysts can gather detailed and accurate information about its quality, performance, and any potential issues.

Isn't sampling often used to determine product quality?

I would say C too.

Would say C. Survey

B. o Observation involves directly observing the product in real-world contexts, such as during manufacturing processes, usage, or interactions with customers. This method allows for firsthand assessment of product quality, identifying any defects, issues, or areas for improvement. Observation can provide valuable insights into the actual performance and characteristics of the product, making it a powerful tool for evaluating quality. While surveys can also provide valuable feedback on product quality, they may rely on participants' perceptions and interpretations, which can be subjective and influenced by various factors. Additionally, surveys may not capture the full range of user experiences and may be limited to the specific questions asked. Overall, both observation and surveys have their strengths and limitations, and the choice between them should be based on the specific research objectives and constraints.
