Manoj's response was insufficient, as he stated he had "no idea" about how to approach simplifying a complex financial service product. This indicates a lack of understanding or experience in product management and user experience design. In contrast, the benchmark response provided a comprehensive and structured approach to addressing feedback effectively, demonstrating a clear process for simplifying products while maintaining core functionalities. Manoj should aim to develop a framework for tackling such challenges, even if he hasn't encountered them directly.
