Review Questions

• How does usability impact user experience in product design?
  • Usability has a direct impact on user experience by determining how easily users can navigate and interact with a product. When a design prioritizes usability, it allows users to accomplish their tasks without confusion or frustration. This leads to higher levels of satisfaction and engagement, as users are more likely to feel confident in their ability to use the product effectively.
• Discuss the relationship between usability and accessibility in design.
  • Usability and accessibility are closely linked concepts in design. While usability focuses on how effectively and efficiently all users can interact with a product, accessibility ensures that those with disabilities can access and use it just as easily. A product that is both usable and accessible is one that caters to a diverse range of users, enhancing the overall experience for everyone by accommodating different needs and abilities.
• Evaluate the importance of conducting usability testing in the development process of a new system.
  • Conducting usability testing is crucial during the development of a new system as it provides valuable insights into how real users interact with the design. This process helps identify pain points and areas where users struggle, which can lead to targeted improvements before final release. By prioritizing usability testing, developers can create more intuitive systems that meet user needs effectively, ultimately enhancing user satisfaction and reducing support costs after deployment.
