Varun's response indicates a basic understanding of impact analysis and the identification of changes required for the e-commerce application. However, it lacks the detail and structure present in the benchmark response. While he mentions assessing the "as-is" and "to-be" states, he does not provide specific examples or recommendations that resulted from his analysis. To improve, Varun should elaborate on the specific findings from his analysis, including any challenges faced and how his recommendations directly contributed to enhancing the application. Providing a concrete example of a recommendation would strengthen his response significantly.
