Product use testing has several advantages:
I. Testing in real customer situations can uncover product strengths and weaknesses that testing in more controlled situations may miss: Real-world testing reveals how the product performs in actual use conditions, highlighting practical issues and benefits that controlled environments might not show.
II. Successful product use tests can lead to generate positive word-of-mouth: When customers have a positive experience with a product during testing, they are likely to share their experiences, which can build early market enthusiasm.
IV. Product use testing can be designed to test internal processes like installation and customer service: This ensures that the entire customer experience, not just the product performance, meets expectations.
Evaluating commercial success (III) is not typically part of product use testing; it's more about assessing usability and functionality before full market launch. References: Crawford, C. M., & Di Benedetto, C. A.
