During the wireframing phase, I conducted two rounds of rapid user testing through online surveys. After analyzing the feedback, I determined the design focus and implemented significant changes.

Feedback indicated that the orientation was extremely helpful for users, prompting me to refine the user flow for the orientation. I added specific content and presented it to educators for validation.

The survey results indicated that parents are looking for a tool to assist with insulin dose calculations, validating the need for an insulin calculator.  Key inputs include total carbs and current blood sugar, which are required for every calculation, while the carb ratio varies between day and night. Target blood sugar and correction factors typically remain constant. Based on these insights, I collaborated with educators to design the user flow and determine the format and layout for each input of the insulin calculator.

By scanning the QR code, parents can interact with the prototype. I gave them specific tasks, recorded their actions, and asked follow-up questions to gather feedback on the design.

The 4 tasks are:
(1) Can you describe the schedule for the second day of orientation? Is it similar to what was covered in the initial education session?
(2) Can you locate the email address for your nurse, Jane, in case of an emergency?
(3) Please navigate through Chapter One, 'Diabetes Basics,'  How would you find all content related to the word 'insulin'? Do you find this function easy to use? In what situations would you use it, and what specific terms would you search for?
(4) Calculate the insulin dose needed for eating 60 grams of carbohydrates with a blood sugar level of 150. After receiving the result, what would your next steps be? Do you find the calculator easy or difficult to use?

To ensure consistency with our client's existing products, I created a new visual style based on the design system references from our client.

For Task 5, three out of five users were unable to calculate the correct result, citing the calculator’s complexity due to an excess of elements. To address this, I implemented three major improvements.

The quiz features both single and multi-choice questions. Users were confused by the multi-choice format due to unclear indications and were also unaware of their progress throughout the quiz. To resolve these issues, I implemented three key improvements.
