Usability Testing

Usability testing was conducted for the Poshmark app. In the beginning stages, card sorting was used. With the results of the card sorting, the lo-fi prototype was developed and then tested. Watch the videos below to see the usability testing for the lo-fi prototype. At the bottom, you can find links to download the script used, consent forms presented to participants, and the final user testing analysis.

User Testing Analysis

Project name: Poshmark app

Tasks assigned were read and displayed to the user as follows:
1. Shop under $20 category
2. Sell clothing
3. View items in your closet

User Time to Complete Each Task:

User Task #1 Task #2 Task #3
Ryan 10 seconds 2 minutes 27 seconds 19 seconds
Hayley 15 seconds 2 minutes 16 seconds
Hope 5 seconds 2 minutes 33 seconds 35 seconds


General Analysis:
All three users were able to complete the entire test in under 9 minutes – which included my instructions, the actual testing, and a demographic survey at the end. The users were able to complete the usability portion of the test-taking an average of three minutes and five seconds. The first task was completed in 15 seconds or less. The second task took users about two to two and a half minutes to complete. This task, in particular, had more steps involved and multiple pages for the users to navigate through so the fact that each user took around the same time means that the task was clear and the process to completion was appropriate and understandable. The users did not encounter many difficulties during testing. There was some confusion with one user regarding the placement of the camera button and the home button. One user was also confused about how to perform the last task, “view items in your closet”. I think that this issue stemmed more from how simple the task was as opposed to the wording of it. The user looked puzzled and I clarified that the item they were trying to view was their own. I purposely put this task after the “sell clothing” task so that the user would be familiar with the images of their imaginary item prior to being asked to view it for sale.

Moving forward, I will place an item on the table prior to asking the user to complete the “sell clothing” task. I think that having the task and an item presented simultaneously will make it more obvious that the user needs to interact with both in order to complete the task. I will also update my lo-fi prototype to have the camera screen be cut out as opposed to having a blank screen with an X. I think the placeholder we use for images, of an X in a box, is confusing for people who don’t understand what it is meant to represent and it causes them to spend more time on the task.
