- 4. Deciding Which Methodology To Use Depends on Several Factors Including: - What Information you are trying to obtain - How far along in the life cycle of the project - Budget (Time as well as Monetary)
- 5. What Is Usability Testing? Usability testing usually involves systematic observation under controlled conditions to determine how well people can use a product.

- 9. What Is Usability Testing in IxD? In interaction design, usability tests are used to measure the interactive user experience associated with a user interface, such a website, software application, or mobile application. “A person’s perceptions and responses(emotional, mental, physical, etc.) that result from the use or anticipated use of a product, system or service...” Factors that influence user experience: 1. System 2. User 3. Context of use

Usability Test Analysis When conducting a usability test, it is optimal to recruit the primary or secondary users of the product. Testing users who are not the primary or secondary users will still yield problems with the product. Testing someone is better than testing no one.

Usability Test Analysis In the early 90s, Jakob Nielson popularized the concept of using numerous small usability tests, typically with only five test subjects each. # Issues found 5 10
- 13. Conducting A Usability Test 1. Recruiting Participants 2. Creating Task List 3. Conducting a Usability Test 4. Usability Test Analysis Typically, participants will perform a set of 5 to 10 tasks. Tasks should represent the most common user goals and have clearly defined criteria for success.
- 14. Conducting A Usability Test 1. Recruiting Participants 2. Creating Task List 3. Conducting a Usability Test 4. Usability Test Analysis When conducting user testing, the researcher reads a participant one task at a time, and allows the participant to complete the task without any guidance. To prevent bias, the researcher follows the same “script” when explaining the task to each participant. The researcher may also ask the participant to talk aloud as he works on a task to better understand the participant’s mental model for the task

Usability Test Analysis When all participants have completed the usability test, the designer will compile the data to determine the severity of each issue that was encountered and provide prioritized recommendations/solutions.
