- How does usability testing differ from user acceptance testing (UAT), and what are their respective goals?1. You have been asked to work as a usability consultant for a company where the development team has created a new version of an existing product. Three important requirements were that the new user interface should be efficient, intuitive and attractive. a. How would you interpret these requirements in the light of your knowledge of Human Computer Interaction? b. The development team claim that their new user interface is more efficient than the old one. Explain in detail how you could measure whether this claim is justified. c. The developers also claim that their new version is already more intuitive than the old one. Explain in detail how you could measure whether this claim is justified.Any weaknesses or disadvantages of usability testing?
- Show how usability improves and enriches the user experience.Usability testing can be expensive and time consuming process. What if I just skip this process all together while creating a user manual? What will the consequences? Why you must need to consider usability evaluation and/or testing through all stages of generating documents or websites?How can we improve the design process by setting measurable goals for usability?
- Explain the concept of user-centered design (UCD) and its phases, including user research, prototyping, and usability testing. Provide real-world examples of UCD in action.What do you think might be the biggest harriers to completion of the user acceptance testing in a timely manner?While conducting tests for usability and user experience, researchers looked at how the test's objectives were specified.
- What are the usability objectives and measures? Describe them briefly with examples.The first step in the usability process is to study the intended users and use of the product. At a minimum, developers should visit a customer site so that they have a feel for how the product will be used. Individual user characteristics and variability in tasks are the two factors with the largest impact on usability, so they need to be studied carefully. When considering users, one should keep in mind that they often include installers, maintainers, system administrators, and other support staff in addition to the people who sit at the keyboard. The concept of "user" should be defined to include everybody whose work is affected by the product in some way, including the users of the system's end product or output even if they never see a single screen. Explain four (4) benefits when know the user.How were the usability and user experience objectives of the assessment divided?
