Usability study
Three usability studies were carried out during the prototyping of this product.
After creating the paper and low-fidelity digital wireframes, it was time to carry out research to determine if users could complete the user flow of the major features and changes I had implemented while trying to see if there were other functionalities that the users would request to be included or that should be removed from the design, to ensure that the design was user-centered. The first was carried out after I designed the low-fidelity prototype, the second was carried out in the process of producing the high-fidelity designs, and the third was carried out after the high-fidelity prototypes had been designed. My main goals were:
determine if the app design was modern and appealing as well as easily navigable
determine if the key features requested by users from the user research carried out at the start of this project were offered by the prototype
Identify any parts of the app where users were getting stuck when trying to complete the main user flow.
assess how user friendly the design of the product was
prioritize feedback in order to iterate further on the design
The participants were people who were customers of FirstBank and made use of their current mobile app as well as people who also made use of other financial apps. As usual, I made certain to include people with various accessibility issues, because designing with accessibility in mind makes a product good for everyone!
The test was conducted remotely on Google Forms, the Reddit community, and in person. Participants were given a link and presented with several tasks to complete in the prototype.
Usability Study Findings
Users were generally satisfied with the prototype's layout and item arrangement. Some suggested experimenting with a collapsed settings menu, although they acknowledged that the expanded version made it easier to find needed functionalities. The addition of the vaults feature was particularly appreciated for enhancing savings habits without requiring a separate fixed deposit account. During the third usability test, many users mistook the prototype for a real app, describing it as 'incredibly realistic.'
Round 1 Findings: 24 anonymous participants
94% success rate on navigating the prototype and initiating and completing a transaction
92% users found the expanded settings menu easier to locate features
20% of the participants expressed confusion on the placement of the logout button for their account
Round 2 Findings: 20 anonymous participants
99% success rate on navigating the prototype and initiating and completing a transaction
98% users found the expanded settings menu easier to locate features
15% of the participants expressed concern on the accessibility state of the transaction entries
Round 3 Findings: 33 anonymous participants
100% success rate on navigating the prototype and initiating and completing a transaction
100% users found the expanded settings menu easier to locate features
45% of the participants observed some inconsistencies in some selection fields
Insights
Based on the results from these usability studies, I was able to map out key insights that would be my guidelines for iterating on the prototype which includes:
Move the logout button to the edit profile section for a more intuitive experience
Create a better onboarding experience and include subtle guides to prompt users while navigating the prototype
Make selection options relevant across the prototype for a more unified look and better user flow
Ensure better accessibility design guidelines while iterating on the porotype to enable better user experience
