5. What is Usability Testing?
Usability testing refers to evaluating a product or service by testing it with
representative users.
6. Benefit Usability Testing
Usability testing lets the design and development teams identify an early problem,
and lets us know what part should be improved
7. During usability test, you will:
• Learn if participants are able to complete specified tasks successfully and
• Identify how long it takes to complete specified tasks
• Find out how satisfied participants are with your Web site or other product
• Identify changes required to improve user performance and satisfaction
• And analyze the performance to see if it meets your usability objectives
8. You Don’t Need a Formal Labs
You can conduct in every place, an effective usability test does not require a
formal lab or any private room. your participant must feel at home and
comfortable.
9. Trying this step, for setting up your own labs.
• Productive cafe or Coworking space
• Preparing voice recorder
• Camera for global activity and main activity
• Screen recorder if the product is digital(apps/website)
• Remotely, with the user in a different location (either moderated or
unmoderated)
11. Moderated Usability Testing
Moderated usability testing is a usability testing technique that involves the active
participation of a trained facilitator or moderator, and is usually performed in a lab
or corporate setting.
14. Quantitative vs Qualitative
Quantitative This type of research is focused on numbers and measurement while
Qualitative research, an approach that’s all about the ‘why’
15. Heuristic Evaluation
method for finding the usability problems in a user interface design so that they
can be attended to as part of an iterative design process.
16. Tree Testing
In a tree test, participants attempt to complete tasks using only the category
structure of your site.
18. PURE
(Pragmatic Usability Rate by Expert)
PURE is a usability-evaluation method in which usability experts assign one or more
quantitative ratings to a design based on a set of criteria and then combine all these
ratings into a final score and easy-to-understand visual representation
23. Isn’t best tips and trick
• Build a persona and segmented your participant
• Describe your product with a meaning short words and make your participant
understand
• Understanding your participant
• Don’t try solving everything at once
• Engage the whole team in the process
• Deep dive into user behavior
• Don’t forget to set the goal
25. PURE Rubric
The step can be accomplished easily by the target user, due to low cognitive
load or because it’s a known pattern, such as the acceptance of a terms-of-service
agreement.
The step requires a notable degree of cognitive load (or physical effort)
by the target user, but can generally be accomplished with some effort.
The step is difficult for the target user, due to significant cognitive load or
confusion; some target users would likely fail or abandon the task at this point.
26. PURE
(Pragmatic Usability Rating by Expert)
PURE is like a Tomatometer for
usability. It provides a score obtained
by aggregating ratings (on a
predefined rating scale)
from a panel of experts familiar
with UX principles and heuristics.
PURE Scores: Measures of Friction
PURE scores for two tasks
27. PURE Scoring By
Task
The PURE score for a product is
the sum of the scores for each
fundamental task that can be
accomplished with that product.
28. How To Conduct PURE
Step 1: Target User Types
Step 2: Fundamental Tasks
Step 3: Happy Paths
Step 4: Step Boundaries
Step 5: Review by Three Expert Raters
Step 6: Interrater Reliability Calculations (IRR)
Step 7: The Decided PURE Score
Step 8: Summing It Up into Green, Yellow, and Red
Step 9 (optional): It’s Not All Quantitative
Step 10 (optional): Comparing PURE Scores
29. Happy Path
The “Happy Path” of each Fundamental Task is defined as the most desired path
to accomplish the task, as specified by the Design Lead.
30. Comparing PURE
Scores
Scores from three PURE evaluations
on the same product indicate
significant UX improvements in
the new versions of the product.
38. Heuristic Evaluation
Jakob Nielsen's 10 general principles
for interaction design. They are called
"heuristics" because they are broad
rules of thumb and not specific
usability guidelines.
#1: Visibility of system status
#2: Match between system and the real world
#3: User control and freedom
#4: Consistency and standards
#5: Error prevention
#6: Recognition rather than recall
#7: Flexibility and efficiency of use
#8: Aesthetic and minimalist design
#9: Help users recognize, diagnose, and
recover from errors
#10: Help and documentation
