Usability & UX
● Section 1 is well structured
● Too personal, maybe say ‘it takes 10mins to…’
○ “On average this took me 10 mins… may depend on the user however…”
● Specific task
○ Re order efficient section - put filters first to talk about what presentation i was
specifically looking for (instead of “desired template” talk about the specifics -
otherwise facts are quite vague)
● Filters - effectiveness
○ Talk about this as effective point
○ Nav bar stays in the same place always
● I like the details you have provided with the use of the figure of the pictures
● Improve quality of screenshots (maybe use milanote)
SUPPORTING CREATIVITY
The range of templates and styles are inspiring for many people, thus
supporting their creativity. However, these are limited due to the paid
features which not everyone can afford.
-bit contradictory.
● Focus on one point or the other

, Usability and UX
Usability
The extent to which a product can be used by specified users to achieve specified
goals with effectiveness, efficiency & satisfaction in a specified context of user.
Cont.
A quality attribute that assesses how easy user interfaces are to use. Also refers to
methods for improving ease-of-use during the design process.
Don’t ask questions
Users shouldn't have to ask how something works, how to do what they want to do.
Good websites should be self explanatory & provide all necessary information.
Importance of usability
● You lose users if usability is not there
● Frustrated users can always head elsewhere
Goals of usability
● Functionally correct
● Efficient to use
● Easy to learn
● Easy to remember
● Error tolerant
● Subjectively pleasing
Functionally correct
● Does what it says on the box
● Does what we expect
● Performs functions the user requires
● May need to meet number of design goals
Efficient to use
● How many hoops?
● Able to perform task?
● Time / actions required to perform tasks
○ This is measurable
● Too many clicks?
Easy to learn
● Effort required to learn task
● How fast for first time users?
● How fast for repeated users?
● Less steps → easier to learn
● How many hoops?
