Personal Responsibilities

  • Tested the device with patients and doctors
  • Communicated with healthcare personnels
  • Researched healthcare policies and certifications
  • Communicated with developers to revise the software according to stakeholders' needs


How might we use our current machine learning technology and IoT expertise to make a device that can provide personalized, accessible and cheap healthcare while increasing the healthcare personnels' time efficiency?



When I joined the company (Arcelik) this device was already developed. However, launching medical devices requires a lot of tests with different parties and certifications. Therefore, I focused on testing the device with patients and healthcare personnels to create a human-centered design rather than just a technology-driven, complex device. For this purpose, I tested usability of the device and device's experience with 59 patients in two different hospitals and I conducted studies with 3 medical doctors in cardiology departments. 



We consistently iterated the user-interface of the device, app and the website regarding the feedback we got from different stakeholders in the usability testing studies. The device and interface became more user-friendly not only for users, also for the medical doctors and nurses. Additionally, we have gotten certifications from Ministry of Health and FDA to implement and market our device in hospitals for prospective patients to get more accessible and cheap proactive treatment. Also we implemented our device with a HaaS (Healthcare as a Service) model that generates profit per report to create a recurring revenue for our company.


Main Takeaways

  1. Creating trust is so important to find patients to test your product. For this purpose, rather than providing a manual or providing videos about how to use the product, it is advantageous to provide in-person information to patiences to create trust and also get better insights through process.
  2. In early stages of testing product, it is better to shadow the nurses first, understand their role, attitude and touch points, then interact with patients with your new device to create better setup for getting insights from patients 
  3. University hospitals have really good opportunities to test your device in early stages of the product development without CE and FDA. Writing academical papers for these kind of tests and studies is a good motivation source for doctors, faculties, university board and also employees of the our companies.  
  4. Designing hardware for health industries requires high-level thinking and problem-preventing mindset. Since when the device get into CE and FDA certifications, there are not so many possibilities to modify the hardware of the device.
  5. Software as a service business model is a good profitable business model for healthcare industry. Prices are high, and service quality,experience and high-technology usage are main drivers for patients to select one hospital on other that most of the hospitals willing to hire the service.
