Context: Group Lessons and Private lessons are an opportunity for English students to apply what they have learned during self-study with other students and with a certified EF English teacher.
In order to take an online English Group Lesson, students had to go through four main steps:

1. Pre-class "Tech Check": verifying that they have proper audio setup and Adobe Flash.
2. Backend check with Adobe that a virtual Adobe Connect room is available (according to our license).
3. Queue for a teacher: waiting for a teacher to mark themselves as available to teach a session.

The problem: when students were lined-up to enter the classroom (queued for a teacher), not all of them was able to enter the classroom right away. With a wait time of up to 10 minutes, 15% of all the students churned during this wait!
Why is this a problem? Not only are Group Lessons very beneficial to student's English education, but EF also makes a fair share of their money from having students complete Group (and Private) Lessons.

The hypothesis: students might churn less if we were more honest with them about what they were waiting for.

The execution: what needed to happen is a cross-team effort in order to:

• Better understand the steps we take in the background in order for student and teacher to meet.
• Decide how we can safely expose these steps to the students.
• Build an experience that effectively communicates these steps.
• A/B test the idea to see if it works.

After going over a few interactions in Sketch, I built a prototype in Framer in order to give the developers an idea of what I had in mind, : (a tool I use regularly to communicate ideas for interactions and show them to stakeholders, or test them with potential users). In the spirit of speed, not all states we built into the prototype.

By showing a progress indicator like this, we were able to increase transparency with our students. The four backend steps required for students to make it into the classroom were now clear to them; they knew why they were waiting:

• Entering the student queue (and determining their position)
• Generating the link for the Adobe Connect virtual classroom
• Waiting for the teacher to make themselves available to the class.
• Entering the classroom

We A/B tested this idea by measuring student cohorts' "seat given" KPI before and after the change.

The news was amazing:
