According to the WHO, approximately 75 million people inject insulin every day (by 2023), and the number is growing. Insulin pens play a crucial role. They are daily companions and an integral part of patients’ lives.
Reason enough to put the user experience at the forefront of product development, alongside excellent usability. This is exactly what we did in this case study.
Initial situation & project
Although insulin pens are everyday companions, they are often designed with usability in mind only. However, patients increasingly want a device that helps them live with their disease without feeling sick. User experience plays a crucial role in this, and this was the focus of this project.
Our core task was to redesign an insulin pen from the ground up. The end result should be a device that people want to use and show off.
Our approach
01
Kick-off & user needs assessment
The project began with a kick-off meeting to set the framework and schedule. This made it clear to everyone involved who had to do what and by when.
Then work could begin on the content. Initially, the focus was on the users. We looked at how insulin pens are currently used. We also found out what influences the user experience and what the challenges are with current devices.
02
First design studies for the housing
The knowledge gained in the first phase formed the basis for the next phase: the first design studies. Our goal in this phase was to generate ideas and turn them into sketches.
In this way, something was created from the start that could be shown and discussed with stakeholders and users. This allowed us to gather feedback early on and incorporate it into the designs.
03
Product design & user testing
The most promising design studies were modeled in 3D for further product design. This gave us the opportunity to print the resulting models on a 3D printer and test and refine their handling.
In line with our data-driven UX design approach, an iterative change between (user) testing and feedback integration was chosen.
In this way, we were able to ensure that the usability and user experience of the housing were high – and thus contribute to our most important project goal.
04
User Interface Design
Of course, excellent usability and user experience also have to do with operation. A parallel step to the iterative completion of the product design was therefore the user interface design of the digital part of the insulin pen.
We started with simple wireframes that made the basic workflows visible and testable. The final user interface was then designed iteratively, incorporating the feedback received.
05
The result
The result is an insulin pen that excels in design, usability and user experience.
We are delighted to have been part of this project and even more delighted with the result.
