CoreTech is a web platform by Hitachi that connects and monitors transformer data in real-time, using algorithms to optimize performance and extend lifespan.
As a UX Research intern, I analyzed the existing interface, conducted user research, and identified key areas for improvement in the next release. Below are the key outputs from different UX/UI design stages. Some details are blurred for confidentiality.Â
I began by gaining a deep understanding of CoreTech—its functionalities, user interactions, and real-world applications. To identify usability challenges, I conducted and documented user interviews, focusing on their pain points, workflow, environment, and key needs. This research provided valuable insights into how users navigate the system, their expectations, and opportunities for improving the interface.
Next, I designed an online survey to gather broader insights from users. The survey focused on identifying general pain points, categorizing common errors, understanding user behavior through personality-based questions, and collecting demographic data. Based on the responses, I selected several participants for in-depth follow-up interviews. In these sessions, users were recorded as they attempted specific tasks within the software, allowing for a detailed analysis of usability challenges and workflow inefficiencies.
I then analyzed the collected data and mapped out user interactions by creating detailed task flow diagrams. These diagrams highlighted how users navigated the software to complete various tasks, with pain points timestamped for clarity. Additionally, I developed a comprehensive site map of the entire software, allowing me to pinpoint problematic pages, inefficient functions, and areas requiring design improvements. In later stages, these insights were paramount in shaping the ideation and decision-making phases, ensuring that user needs directly informed design solutions.
