Working on his project with Denso was a valuable experience, which brought me to amazing people and explored a different area of work as a medical logistic topic. The context of medical cold chain logistics was subtle but vital. The flow involved various stakeholders from a decision-maker level to an assistant in the treatment ward. How do we select participants who will help us understand this subject in a holistic view? We found a load of insights after the session. There were plenty of opportunities for innovative solutions in healthcare service. Our participant and I hope to see the concept becoming a real solution in the near future.
