Life-Saving Equipment

Roles: UX Designer, Quality Assurance

To comply with my non-disclosure agreement, I have omitted confidential information.

Problem

Salespeople needed a tool to sell a life-saving piece of equipment to emergency room staff. It wasn’t feasible to drag the piece of equipment around to demonstrate due to the size and cost. Creating an app that demonstrated the device on an iPad solved many problems.

  • The demonstrations were error-proof, making it easy for the Salesperson to focus on the key talking points.
  • The application didn’t need internet.
  • There were helpful notes baked into the application.
  • The application had all of the information the Salesperson needed.

It was an incredible opportunity to work on this project, as the device was a life-saving tool. The core function of the device was to lower, raise, and essentially control the patient’s temperature to within 0.5 degrees. This is helpful in situations where patients may have suffered from a stroke, heart attack, or even a fall into a frozen lake. The patient’s temperature could be raised slowly, or lowered to slow down trauma to the body.

Paint Points

My first task was to interview the stakeholders to determine the best delivery of the demonstration, as well as the key selling points.

  • Demo devices were too expensive to create, as well as cumbersome and heavy.
  • There was a tight deadline because the semi-annual sales meeting was quickly approaching.
  • The machine was in the midst of major improvements that included the interface, I didn’t have a manual to follow.

Research

Interviews, Contextual Audit,

  • Videos demonstrating the product
  • Access to other Stryker applications
  • Brochure for the device
  • Presentation on the device including talking points for Salespeople

Solution

The major outcome of the interviews was that every salesperson has a company-provided iPad. A local application could demonstrate the machine without the need for continuous wifi or the Internet. It was also ideal because the salespeople already carried the iPad wherever they went. This also gave us more time to work on the application as a way to deliver the app that was already installed on the salespeople’s devices.

Workshop

To prepare for the project, I spent hours watching a video recorded with a smartphone by one of the stakeholders. The video demonstrated how the machine works. The functionality of the machine was simulated, as we didn’t have a patient to run the machine on. Using screenshots from this video, I started to piece together flows, which I glued on several large foam boards and brought to a workshop with stakeholders. In the workshop, we refined and prioritized these flows. An engineering or user manual would have been helpful, but neither had been created yet. There was actually talk of using the Interaction Design Documentation to create a user manual.

Device Audit

The intricate screens of the app required extreme attention to detail. Each screen of the machine was documented and the options, buttons, and functions were detailed. Since there was no manual, I had to rely on a prototype of the device. I met with my subject matter expert three different times to nail down the functionality of the machine.

Wireframes and Prototype

I developed a total of five flows, one of which was an alarm scenario. Each flow was wired and prototyped. The client was insistent on portrait orientation. Key talking points were provided for the salesperson on almost every screen. The talking points were excellent guidance on selling the machine.

Quality Assurance

I assisted with Quality Assurance since the machine‚Äôs functions are so intricate. I was the only one who could double-check the intricacies of the screens, as no manual had ever been written by the engineers. I ran the demo machine over and over, hoping that it was close enough to the engineer’s intentions. In the end, the engineers of the product were so impressed with my interaction design document they said they were going to use it as the manual.

Outcome

The best way to measure a project is when the company asks for another project. This was the first two years worth of successful projects with this client.
