So it begins

Casual namedropping

It took me quite some time to put together this case study due to its natural complexity. For this story to work, I broke it down into two distinctive parts:

  1. Iterating on an existing feature
  2. Leading its integration into different ecosystems

With that being said, let’s start by first naming the key actors of our story:

Bertha App Logo

Bertha

Bertha is a spin-off app from Mercedes-Benz that allows people who don't own a Mercedes to browse for cheap fuel prices and also, to pay for fuel straight from the app.

Mercedes Me App Logo

Mercedes Me

Mercedes me is a companion app that enables Mercedes-Benz owners to interact with their vehicles and purchase additional services.

First things first

What are we trying to accomplish?

Back when I was leading the design efforts for the Bertha app, I was approached with the task of exploring how an integration between Bertha + Mercedes me apps could look like.

It's worth mentioning this happened during peak pandemic times and social distancing was leading all conversations.

After a few product discovery sessions, we decided to break that down into two phases:


α

Perfect the digital payment flow

As Bertha Pay (the digital payment SKU) was already live for some time, we had a juicy repertory of insights on improvements we could do and opportunities to explore.

β

Integrate the feature into the Mercedes-Benz ecosystem

The goal was to enable Mercedes-Benz owners with a contactless and convenient way of paying for fuel without going into a gas station.

Perfect the digital payment flow

What are the pain points & opportunities?

TL;DR; Talked to a whole lot of people to better understand what were the main topics we had to address

We went through the entire pre-payment journey to understand where people got stuck, which tasks we could simplify, how to strengthen the value proposition, and also how to optimize the revenue streams.

We approached the problem framing from several angles, including:

Exploration icon

Discovery sessions with stakeholders

To align on expectations, define key metrics, and better understand the dependencies

Research icon

User Research

Qualitative ≈ 15 users
Quantitative ≈ 1k users

Find icon

Field sessions at gas stations

To observe in real life how consumers and station staff interacted with our solutions

Process icon

Lightning talks with Customer Service

To surface the most frequently reported complaints

Code icon

Deep dive into the payments API

To understand which kind of data we could pull from the payment gateway API

{α}
Perfect the digital payment flow

Focusing on the right things

Based on what we learned from our users & stakeholders, we drafted the following hypotheses:

We Think That

People feel uncomfortable paying with their phones at a gas station when they get the bad eye from other customers that are unaware they can pay digitally



Which is Why

We need to reduce the time Bertha Pay users spend at the gas station

We Think That

People get anxious about something going wrong with their payment once they leave the gas station, as it can often lead to a police report



Which is Why

We have to be more explicit as to when it’s safe to leave the gas station

Still here?

I know, it's a long one! The first bit was about refining the feature and now I will show you some of the methodologies I applied to keep everyone aligned.

I bet you have questions and I might have the answers! Why don't you ?

Integrate the feature into the Mercedes-Benz ecosystem

Designing at Scale

Now that we managed to perfect the feature (wow), we felt confident enough to  expand it to millions of happy Mercedes-Benz owners.

In case you already forgot, this was a two-step project. A reminder of what the β side was about:

β

Integrate the feature into the Mercedes-Benz ecosystem

The goal was to enable Mercedes-Benz owners with a contactless and convenient way of paying for fuel without going into a gas station.

During the discovery & exploration phase of the project, we already looked into what was available in the Mercedes-Benz ecosystem and spotted existing touchpoints we could tap into.

Mercedes-Benz already had a live service for electric cars to find and recharge the vehicles. And that happens to be exactly what we needed.

The journeys were essentially the same and that would make the integration  of our digital fuelling feature more resource-efficient.

Q&A

Reflect Upon

Guest avatar asking question

What was the most challenging part of the project?

Madsen Vale avatar

Working on a project that involves several divisions can be daunting so it’s important to always get the right people in the right meetings

Guest avatar asking question

What was your biggest a-ha moment?

Madsen Vale avatar

When working with third-party services it’s always helpful to check their API to see  which data points we can get

Guest avatar asking question

What were the biggest limitations you found?

Madsen Vale avatar

There’s only so much one can accomplish with a digital application. We’ve considered awareness marketing campaigns at gas stations to other customers would know that some people are paying with their phones

Guest avatar asking question

How did you go about user testing?

Madsen Vale avatar

For consumer services that interact with physical spaces doing it behind a screen is not enough. Field observation is key

Guest avatar asking question

What annoyed you the most?

Madsen Vale avatar

Take into consideration the cross-app integration, like banking notifications for example.

Guest avatar asking question

What would you have done differently?

Madsen Vale avatar

Some things can’t be solved with a digital interface. One idea we had during development was to introduce car stickers that indicate people who didn't go into the gas station to pay using digital payments, this way we could avoid other people calling the police on them. Yes, it happened.

Guest avatar asking question

Why the images here looks so...faint?

Madsen Vale avatar

As it's the first time I introduce dark mode on my portfolio, I added a "glare counter" mechanism to not burn people's retinas with overly bright images. If you wanna know the trick, I can tell you one someday.

Madsen Vale avatar

Ok Harold, we ran out of time. If you have more questions, find me here

...and don't hide the pain!
