4. WHAT IS USABILITY TEST?
• Usability testing is a way to see how easy to use something
is by testing it with real users.
• Users are asked to complete task, typically while they are
being observed by a researcher.
• To see where they encounter problems and experience
confusion.
• If more people encounter similar problems,
recommendations will be made to overcome these usability
issues.
5. USABILITY TESTING EVALUATES EASE
OF USE
• Usability method is a method used to evaluate how easy a
website is to use.
• The test take place with real users to measures how usable
or intuitive a website is and how easy it is for users to reach
their goals.
6. IMPORTANCE OF USABILITY TEST
• The goal in usability testing is to understand how real users
interact with your website and make changes based on the
results.
• It is important to be sure that your app or website is easy to
navigate and that tasks can be completed with ease,
otherwise people will leave and go to a competitor’s site.
• The primary purpose of a usability test is to gather the data
needed to identify usability issues and improve a website or
app’s design.
• Even the best web design and development teams can
benefit from usability testing as the tests indicate trouble
spots for users and the areas where they are getting stuck or
confused.
7. COMPONENT OF USABILITY TEST
• In usability test, there are two groups: end user and
observers.
• Construct a scenario for users to accomplish a set of tasks.
• The users try to accomplish this set of tasks under
controlled condition.
• Observer watch or measures their overall success and
identify the problem.
8. KEY DIFFERENCE BETWEEN
USABILITY AND TRADITIONAL
TESTING
• The key difference between usability and traditional testing
(bug testing, acceptance testing etc.) is that usability testing
takes place with actual users or customers of the product.
• While traditional testing might be undertaken by a
developer, designer or project manager, usability testing
removes any bias by collecting feedback direct from the
end user.
10. COMPARATIVE USABILITY
• Used to compare the usability of one website with another.
• Comparative test`s are commonly used to compare a
website against peer or competitor sites.
• It can also be used to compare two design to establish
which provides the best user experience.
11. EXPLORATIVE USABILITY TESTING
• Before a new product is released, explorative usability
testing can establish what content and functionality a new
product should include to meet the need of its users.
• Users test a range of different service where they are given
realistic scenarios to complete which helps to highlight any
gaps in the market that can be taken advantage of and
illustrate where to focus design effort.
12. USABILITY EVALUATION
• This is a test of a new or updated service either pre or post-
launch.
• This usability test introduce users to the new design to
ensure it is intuitive to use and provides a positive user
experience.
• The aim of the usability evaluation is to ensure any
potential issues are highlighted and fixed before the product
is launched.
13. SUMMATIVE USABILITY TESTING
• At the end of a development stage.
• To measures or validate the usability of a product.
• How usable is this product.
15. 5 E`S OF USABILITY TEST
• Effective: How completely and accurate the work or
experience is completed or goals reached?
• Efficient: how quickly this work can be completed?
• Engaging: How pleasant and satisfying it is to use?
• Error Tolerant: How well the product prevents errors and
can help the user recover from mistakes.
• Easy To Learn: how well the product supports both the
initial and continued learning.
16. WHY DOES USABILITY MATTERS?
• Usability can save time, money and lives.
• On the web, usability is a precondition for survival.
• Applications, usability can determine market share.
17. STEPS FOR USER TESTING
• Plan user tests.
• Conduct user tests.
• Analyzing findings.
• Present finding.
• Modify and retest designs.
18. WHEN TO TEST?
• Test early and test often.
• Identify problems before they get coded.
• When validating claims regarding your product or against
competitors.
19. THINKING ALOUD METHODOLOGY
• Observe user behavior.
• Listen to user feedback.
• Facilitator stays quiet, observer, take notes.
• Test one user at a time.
• Mainly qualitative.
20. DECIDING WHAT TO TEST
• Understand Requirements
what do user want to accomplish?
What does the company want to accomplish?
• Determine the Goals
what tasks does the web site or application support?
• Decide on the area of focus
Tasks that have the most impact on your site
Typical task
Most critical tasks
21. CONCLUSION
• Usability tests evaluate the overall user experience by
measuring the relative ease with which end users can
accomplish a set of tasks that a typical user of the app or
website would need to accomplish.
• Usability testing is a method of evaluating a website or
app’s readiness for release by testing it with real users who
are part of the target audience. Usability tests evaluate the
overall user experience by measuring the relative ease with
which end users can accomplish a set of tasks that a typical
user of the app or website would need to accomplish.
