What is UX and What is Usability?

UX or USABILITY, WHICH ONE IS GREATER?

UX vs. USABILITY

TESTING PRIORITIES Maslow's hierarchy of needs is a theory in psychology proposed by Abraham Maslow in his 1943 paper "A Theory of Human Motivation"

TEST DIMENSIONS...

USABILITY TESTING REPRESENTS THE GREY ZONE!! Software nature is almost the same; whether it does not work, or it works somehow...

USABILITY EQUATION...

HOW TO MEASURE USABILITY?

EMOTIONS ARE IMPORTANT...

WHEN TO DO USABILITY TESTING? ‘Testing with one user early is better than testing 50 near the end’ Steve Krug

EARLY or LATE IN THE SDLC?

WHO WILL DO THE USABILITY TESTING? Testers? Users?

TESTERS or USERS?

10 USABILITY HEURISTICS - Nielsen Norman

USABILITY TESTING TECHNIQUES User Research Usability Testing Contextual Inquiry Card Sorting Diary Study Eye Tracking Focus Group Remote Testing Individual Interview Tree Testing Service Safari User Testing Shadowing Survey Persona Experience Map Expert Analysis Analytics Review Conversion Optimization Cognitive Walkthrough A/B Testing Competitor Analysis Multivariate Testing Content Audit Split Testing Heuristic Evaluation

WHERE TO DO USABILITY TESTING? In the Lab In the Wild

USER OBSERVATION IS SOMETIMES HARD...

WHAT KIND OF EQUIPMENT IS NECESSARY IN USABILITY TESTING? Eyetracking Electroencephalography (EEG)

HOW MANY USERS ARE NEEDED FOR USABILITY TESTING?

USABILITY TESTING DOES NOT SHOW STATISTICS... If 8 out of 10 participants in a usability test successfully completed a task, Can you say that 80% of users in the larger population will be able to complete ● it? No, you can’t. ●

EXCUSES ARE NOT VALID...

Users Are Important!

USERS ALWAYS HAVE A POINT...

USERS ARE MOST OF THE TIME SELECTIVE... 60% easy to use 80% of the Users & use 40% easy to learn 20% of the features No such an app for everyone rule Pareto Rule

USERS ARE GENERALLY OPEN TO CHANGE... User don’t hate change, they hate you! User hate change, that doesn’t make their life better.

USERS SHARE...

USERS ARE EMOTIONAL...

USERS NEED CARING... Easy to Use doesn’t mean good User Experience!

Mobile has Challenges!

USERS ARE MOBILE... “Carry” Principle Mobile Phone is always carried “Privacy” Principle Mobile Phone is not given to anyone “On” Principle Mobile Phone is always turned on “1 meter” Principle Mobile Phone is always 1m away

USERS CRITICIZE...

USERS TRIGGER INNOVATIVE SOLUTIONS... APP Store Review & Star Service | 100% Real Users!!!

USERS DELETE... • 50% of users are deleting a Mobile App, for a Single BUG ! • 50% of apps are downloaded and used just once !

USERS FACE WITH STRANGE BUGS... Heisenbug is a classification of an unusual software bug that disappears or alters its behavior when an attempt to isolate it is made .

USERS DO HAVE FAT FINGERS...

There are many Usability Testing Tools!

THERE ARE MANY TOOLS FOR USABILITY TESTING...

DO NOT AUTOMATE USABILITY TESTING... Usability testing requires human feedback...

FINAL WORDS... Do not just focus on functional testing, ● Do usability testing throughout the lifecycle, ● Get to know your users, ● Their characteristics, their needs, their pain points... ○ Prioritize your users, ● Try to do expert evaluation as well as user observation, ● use ww usability heuristics and follow the trends, ○ Try to use tools and new technology but remember; ● Most of the usability testing happens out in the wild. ○ Share your knowledge for the betterment of Testing. ●
