User Testing Synthesized Learnings

I would like to thank my 5 participants for this user interviews.
Luckily, the overall concept made sense to the target users, and they liked the idea. The interviewed diabetics think this application is a great innovation and will make diabetics’ life easier and help them better manage their diabetes.

Improve overall flow
Make sure that the overall concept and flow are straightforward, nothing seems confused or disoriented.
Refine the features
Obtain feedbacks from users about key features and simplify the features to make them more efficient.
Make emphasis
Ranking the feature, and based on the result, emphasize the one/two seems most useful and attractive for the users.
I have talked to 5 users, one has type 1 diabetes, one has type 2 diabetes, one is a nurse practitioner and two classmates, and all of them give me very helpful and positive feedback.
I went through some background questions with them first to know them a little bit better, then I asked many diabetes-related questions. For my users, they either have diabetes or know someone who has diabetes, therefore, I have a better understanding of diabetics’ life now.
I introduced my start-up idea with them and went through my case study website to explain the value proposition, problem, solution and storyboard for them. I asked their feedbacks about the concept.
I showed them my prototype feature by feature. After testing each feature, I asked for feedback and experience. After testing all the features, I asked them to rank each feature based on their preference and experience.
In the end, I codesigned my app with them, we discussed how to make improvements to make users have better experience when they are using the app.
What’s diabetics daily life?
I want to know what they would do differently compared to non-diabetic, and how different.
Any frustrations or concerns you had while managing your diabetes?
I want to know what’s the difficulties they experienced when they are managing their diabetes, so I can solve those difficulties in my app.
Are you currently taking care of your nutritional intake with a professional nutritionist?
I wondered if they are currently meeting a nutritionist or not, and their knowledge about the nutritional intake, and how much do they pay attention on nutrition while they are managing their diabetes.
Diabetics are very strict control their blood sugar level, and there are many factors would affect their blood sugar level.
Nutritional intake is the most important factor when managing diabetes.
Exercise amount, sleep quality and stress level also affect blood sugar level a lot.
It’s very beneficial to have a nutritionist help you for nutritional intake, not just take track of carb amount, also finding substitute food for you.
When exploring recipes, the amount of calorie, protein, carbohydrate, fat and fiber are really important for diabetics.
