The promotion more massive, the student registration is following the condition. We found some new issue as the MVP features as mentioned, we have no registration page yet cause ops team need to enroll one-by-one hundreds of new registration when attending the exhibition. It cause longer time to enroll all enrollments, for example when adding 10 students to 6 courses, we need about 4 mins.
Due the Problem, Try to Solve with Exploring Context and Iterating the Design. I gather information from ops team how they running the flow and try exploring some context and discuss with them. Then, design based on contexts and information I got from ops team.
