We began by developing user stories to capture all potential scenarios in the account opening process and identify key requirements. Product owners helped consolidate the initial needs. Business analysts then further clarified the business requirements through interviews and analyses. Design workshops were held to directly engage stakeholders. In these workshops, we obtained insights into their perspectives by sketching out ideas and prototypes. Wireframing and UI design for tablet and web system was conducted in Figma. We followed an agile methodology, facilitating close collaboration with stakeholders at each sprint through tools such as Jira, Trello, and Slack. This collaborative approach allowed for regular feedback to be incorporated continuously. It also helped ensure the solution evolved optimally to meet business and user needs.
