Match between system and real world
Positive - Uses standard vocabulary used in other applications, such as ‘Create’, ‘Cancel’, ‘Tags’.
Negative - ‘Quick Save’ might seem to users that it is where they save products instead of comparisons. Hence, there might be a mismatch between users’ expectations and the system.
Negative - Users find it unintuitive to remove a product listings from the comparison table by swiping down.
Help & Documentation
Negative - Our users were confused about the term “Quick Save”
Consistency and Standards
Negative - The color and positioning of the primary button and secondary buttons are not standardised especially in the Quiz pages.
User Control & Freedom
Negative - Our initial idea implementation was to have the product listings within each comparison table auto-populated by the app with the recommended products. Users find it restrictive that the product listings inside a saved comparison are populated by the app instead of them having an agency to choose what products they want to see in each comparison table that is saved.
Negative - System doesn't allow users to delete comparisons of products even if they save a comparison by mistake.
Error Prevention
Negative - The app in general has little error prevention in the form of pop ups etc.
Flexibility and Efficiency of Use
Negative - the quiz felt very long and user cannot anticipate what is coming next
Negative - System doesn’t allow user to select only the products they want to save. It only allows users to save the entire comparison table.
Aesthetic and Minimalist Design
Positive - Generally consistent and uncluttered design
Visibility of System Status
Positive - The headers and progress bar allows the user to understand what page they are on and how many pages are left. Whenever the user navigates to a new page, the system is able to give appropriate feedback through darkening of bubbles in the progress bar.
Negative - No feedback to user after saving comparisons.
