Tell me about a time when you had to engage in user testing and review feedback to improve designs. What changes did you make based on the feedback?

Sample answer to the question

One time in my previous role as an industrial designer, I was tasked with creating a new product concept for a client. After completing the initial design, I conducted user testing to gather feedback and insights. Based on the feedback, I made several changes to improve the design. Firstly, I adjusted the ergonomics of the product by modifying the handle to ensure a more comfortable grip. Secondly, I enhanced the visual appeal by incorporating a sleeker and more modern aesthetic. Finally, I refined the functionality by adding additional features based on the users' suggestions. These changes not only improved the overall user experience, but they also resulted in a more marketable and competitive product.

A more solid answer

During my time as an industrial designer, I had the opportunity to engage in user testing to gather feedback and improve design solutions. One particular project comes to mind where I was tasked with designing a new ergonomic tool for a manufacturing company. After creating initial sketches and 3D models, I conducted user testing sessions with a group of employees who would be using the tool on a daily basis. The feedback I received was invaluable and allowed me to make significant changes to the design. Firstly, users expressed concerns about the handle being too small, leading to discomfort during use. I addressed this by increasing the size of the handle and incorporating a soft grip material for added comfort. Secondly, users mentioned that the tool was too heavy, which could lead to fatigue. To resolve this, I evaluated different materials and optimized the internal structure to reduce weight without compromising strength. Lastly, users suggested the addition of a safety feature to prevent accidental activation. I worked closely with the engineering team to incorporate a fail-safe mechanism that required a deliberate action to activate the tool. These changes not only improved the functionality and user experience but also increased the safety and efficiency of the tool.

An exceptional answer

As an industrial designer, I understand the importance of user testing and feedback in creating successful designs. In one project, I was assigned to redesign a household appliance for a leading consumer electronics company. To gather feedback, I organized a user testing session with a diverse group of participants, including different ages and backgrounds. During the session, I used various methods to capture feedback, such as structured questionnaires, interviews, and observations. The feedback revealed several areas for improvement. Firstly, users expressed confusion about the control panel and struggled to navigate the different settings. To address this, I conducted a thorough analysis of the user interface and redesigned it to be more intuitive and user-friendly. Secondly, participants mentioned that the appliance emitted a loud noise during operation, which was disruptive and unpleasant. I collaborated with the engineering team and conducted further research to identify the source of the noise. Through careful design modifications and material selection, we were able to significantly reduce the noise level. Additionally, participants shared their desire for a more compact and aesthetically pleasing design. I worked closely with the product manager and conducted market research to identify the latest trends and preferences. The final design incorporated sleek lines, premium materials, and a compact form factor, resulting in a visually appealing product. Overall, the user testing and feedback helped me identify key areas for improvement and make design changes that greatly enhanced the functionality, usability, and aesthetics of the appliance.
