Users Define Quality. Overview:  What is usability testing?  How is it different from functional testing?  Why is it important?  Where do I start?

Users Define Quality. Usability Testing is:  a means for measuring how well people can use some human-made object (such as a web page, a computer interface, a document, or a device) for its intended purpose

Users Define Quality. Usability Testing:  involves carefully creating a scenario, or realistic situation, where the person performs a list of tasks using the product being tested while observers watch and take notes. Functionality Testing:  involves testing and evaluating that the entire application performs according to the system specification or requirements documentation.

Users Define Quality. Why is usability important?  Competitive marketplace  Instant product service replacement often available  Difficult to recover lost reputation  High visibility, particularly in web-based applications  Negative media or review publications

Users Define Quality. How do we evaluate usability?  Usable Design -Can I find what I am looking for?  Usable Functionality -Does it do what I expect it to?

Users Define Quality. Usable Design:  Lay out  GUI  User flow  Ease of finding things

Users Define Quality. Usable Functionality:  Error handling  Performs intended service  Expected use

Users Define Quality.  Both usable design and usable functionality issues are cheaper to fix in the design phase  Reduces risk of customer visibility  Test should be revised and repeated after changes are made

Users Define Quality. Process vs. Cost:

Users Define Quality. Usability Labs:  Audio recording  Video recording  Application navigation recording  Eye-movement tracking  Two-way mirrors

Users Define Quality. PLAN:  Understand & identify your end users  What do you want to know? Identify goals  Develop your script  Develop pre and post test questionnaires

Users Define Quality. Test Scripts should be: - Short. - Specific. - Realistic. - Simple.

Users Define Quality. EXECUTE:  Pre-test questionnaire  One-on-one time -Keep them talking! -Ask “Why?”  What to measure -Accuracy -Time on Task -Recall -Emotional Response  Post-test questionnaire

Users Define Quality. EVALUATE:  Compile tester demographics, test results, and feedback  Present your findings and recommendations -Based on risk/visibility  Do multiple iterations of test after changes are made
