1. Story and practice background

We conducted in-house testing ahead of the launch of the service. However, the membership registration completion rate was only 10%. When we traced the cause, we found that in addition to email and password, there were a total of 12 required fields in the registration form, including 'zip code search', 'detailed address', 'recommender ID', and 'select preferred hobby'. The bigger problem was that if a user made a typo even by one character while entering the password confirmation, the screen would be refreshed and all previously entered emails and nicknames would be reset. Tired users left the service, saying, “I will break my head while signing up.”

2. Learning objectives

• In the multi-step form structure of membership registration, factors that increase user cognitive fatigue can be found from the user's perspective.
• The login and sign-up steps can be designed separately at a later point in line with the progressive onboarding technique.
• Screen connection flow and state recovery requirements can be described in the improvement report so that previously written content is preserved in the event of an error.
