Our team took charge of the concept design phase, working closely with the company to develop innovative and highly scalable solutions. We conducted extensive customer research, shaping the new concept and creating a fresh design language. The implementation phase involved the use of our "Validation Sprint" process, during which we designed and prototyped the app in collaboration with the company's experts. Real users were involved in two months of rigorous testing. As a result, we contributed to the creation of the Smart Alarm System (SAS), an all-new hardware lineup that featured exciting updates and improvements. This solution marked the company's expansion into the Smart Home territory, providing users with enhanced safety, security, and convenience. Through a careful balance of personal and matter-of-fact interactions, we successfully handled the challenge of presenting life-and-death matters on a platform often associated with breezy entertainment and simplistic interactions. The collaboration extended beyond product design and user research to include mobile engineering for Android and iOS, as well as UX copywriting. This comprehensive collaboration ensured a successful outcome.
