HOW TO WORK ON THIS ASSIGNMENT (EXAMPLE ESSAY / DRAFT)
Introduction Best Buy is one of the largest electronics retailers in the United States, with an extensive online presence. In this review, we evaluate the usability of Best Buy’s e-commerce website, using metrics and methods presented in Interaction Design by Helen Sharp, Jennifer Preece, and Yvonne Rogers. We also apply the Nielsen 10 heuristics for usability design to identify specific areas for improvement.
Metrics In evaluating the usability of Best Buy’s e-commerce website, we used the following measurable criteria:
- Efficiency: How easily and quickly users can complete tasks on the website.
- Learnability: How easy it is for users to learn how to use the website.
- Error rate: How frequently users encounter errors while using the website.
- User satisfaction: How satisfied users are with the overall experience of using the website.
We also collected data on the number of clicks required to complete tasks, the time it took to complete tasks, and the frequency of user errors.
Nielsen 10 heuristics We applied the following Nielsen 10 heuristics for usability design to evaluate Best Buy’s e-commerce website:
- Visibility of system status: Best Buy’s website does a good job of providing users with feedback on their actions, such as displaying the number of items in a shopping cart or the status of an order.
- Match between system and the real world: The website’s navigation and organization are similar to what users would expect from an electronics retailer, making it easy to find products and information.
- User control and freedom: The website allows users to easily undo and redo actions, such as removing items from a shopping cart or going back to a previous page.
- Consistency and standards: The website follows established conventions for e-commerce websites, such as displaying product images and descriptions, and using a shopping cart to store items.
- Error prevention: While the website does provide some error prevention, such as prompting users to confirm the removal of items from a shopping cart, it could benefit from more proactive error prevention measures.
- Recognition rather than recall: The website provides users with clear and consistent navigation, making it easy to find products and information without having to remember specific details.
- Flexibility and efficiency of use: The website provides users with multiple ways to find products and information, such as using search or browsing by category, which can accommodate different user preferences and goals.
- Aesthetic and minimalist design: While the website is generally visually appealing, it could benefit from a more minimalist design that reduces clutter and distractions.
- Help users recognize, diagnose, and recover from errors: The website does provide some error messages and guidance, but it could benefit from more specific and actionable instructions for users who encounter errors.
- Help and documentation: The website provides users with various forms of help and documentation, such as a customer service chat, but it could benefit from more accessible and visible help options.
Conclusion Overall, Best Buy’s e-commerce website provides users with a relatively easy and efficient shopping experience, but there are areas where it could be improved. By using measurable criteria and Nielsen’s heuristics for usability design, we were able to identify specific areas for improvement, such as more proactive error prevention measures, clearer error messages and guidance, and more visible help options. Implementing these changes could enhance the usability of the website and improve user satisfaction.
