Week 8: Pink Bagels and Big Decisions

Hello, and welcome to our weekly updates! Every week, one of us will share all of the miscellaneous stuff that we've been up to, so that you can keep up with the day-to-day of Team Conduit!

In this edition: choosing an idea and pink bagel testing.

Choosing an Idea

We had tested our three main ideas individually, and had found that all three were viable options, but we had a lot of questions about the interfaces of each idea that hadn't been resolved. But it would be an infeasible amount of work to resolve those issues fully for each prototype, so we decided that it was time to tentatively select one idea. We could then create multiple prototypes for one idea, to make the scope of our tests more managable.

Our three ideas were:

  1. Allowing an EV owner to request a charging station that is in use by another EV owner.
  2. Creating a notification system so that an EV owner can get custom notifications when their car is charged to a desired level.
  3. Helping EV owners find businesses with charging stations nearby. E.g. "find me a dinner place with a charging station nearby."

After much discussion, we chose the first idea for the following reasons:

  • We had seen a need for a tool such as this one during our needfinding exercise.
  • We found that EV owners had a solution for this problem, but that it was a poor one.
  • We were excited about the idea and thought that it was both feasible and would create interesting technical challenges.

We are incredibly excited about this choice of idea, and we have begun thinking about the technical challenges it will bring as well as the marketing and design challenges.

Pink Bagel Testing

Pink bagel testing is a form of A/B testing where only one tiny element of the design is changed, such as the color of an icon. This week, as part of our pink bagel testing, we are running an ad campaign on Facebook, where the "pink bagel" is the text of the ad. In other words, we have two different newsfeed ad creatives using the same image but different text. Our goal is to understand how users respond to questions versus requests in ads.

We decided that we could also get more utility out of these campaigns by creating three different landing pages, and then running each of the two ads for each of the three landing pages. Each landing page contained a prototype, which then led to a survey.

Our goal for the landing page was to determine which method of communication between users is best. We had brainstormed three main methods of notification: ping only, preset messages + custom messages, and custom messages only.

  1. Ping only allows the person who is requesting a charging station to send a push notification to the EV's owner, without any customization. This is the most lightweight of the communication interfaces.
  2. Preset messages + custom messages allows the person who is requesting a charging station to choose out of several pre-written messages (messages designed by us and messages that were sent previously), but also gives them the option to create a new custom message.
  3. Custom messages is like a traditional messaging service in that the requester can simply type out a message to the person using the charging station.

We decided that having data to compare these three different communication methods would be useful, so we decided to create three prototypes from the charging station requester's perspective using these three different methods of communication. These would then be the landing pages for the ads, and users would be able to fill out a typeform survey evaluating the prototypes in terms of ease of use and usefulness.

These tests are ongoing, so results are to come.
