User Testing
During this phase, the focus was primarily on the blood availability feature of the platform. The goal was to gather external feedback early in the development process. Five participants were asked to navigate the prototype without guidance to assess
-
The intuitiveness of the navigation.
-
Identification of any missing features or information that would have been useful.
-
Their overall feelings and experiences during the process.
Areas for Improvement:​
-
Users cannot filter by blood group to check availability
-
The amount of blood is unclear because there are no units provided with the color codes
-
Limited information because there is no option to select a blood group.
User Testing
"Current Blood Availability"
"Missing Blood Type"
Based on testing feedback, I added an option to select the blood type, which makes it easier to find the nearest location with the specific blood group available.
"Color Representation"
"Blood Quantity"
I thought users would understand the amount of blood left by looking at the space in the bottle. However, changing the color based on the quantity made it much easier for them to understand.
"Blood Quantity"
"Units Mentioned"
Adding a "Learn" button helps users understand how many units are available for a specific color.
