Assessing the Usability and User Acceptance of an E-Commerce Application Through a Combined SUMI and TAM Framework

In this study, a combined approach using the Software Usability Measurement Inventory (SUMI) and the Technology Acceptance Model (TAM) is employed to evaluate an e-commerce application's usability and user acceptance. Usability plays a significant role in shaping consumer satisfaction, while user acceptance is crucial for the application's success in a competitive market. This research explores how users interact with the platform, aiming to identify usability issues and factors influencing user acceptance. Key usability criteria, including visual appeal, information clarity, and ease of navigation, are analyzed alongside TAM constructs such as perceived usefulness and ease of use. The study's primary objective is to uncover the platform's strengths and weaknesses, providing insights into functionality, design, and user acceptance. By addressing identified usability concerns and understanding the factors driving user adoption, the research aims to enhance customer satisfaction and engagement. Ultimately, the findings are expected to guide the development of a more user-friendly interface, improving the e-commerce platform's overall effectiveness, user experience, and market competitiveness.
