DAT Mobile · Post-Migration Recovery

Restoring trust by diagnosing the problem beneath the pushback.

After a platform migration changed posting behavior and triggered customer pushback, I helped a cross-functional tiger team isolate a subtle mobile issue: real-world text settings had quietly reduced scanning efficiency.

01 · What the migration broke

A platform move solved an internal technical problem but created a front-end trust problem.

Design was not involved in the original migration. After migration, posting metrics changed significantly and Sales and Customer Support heard substantial customer pushback. A cross-functional tiger team formed to understand why.

Most recovery work of our team focused on web, where workflow and posting problems were larger. However, our mobile team noticed patterns we could quickly adjust, and that's this story.

Posting and Searching shifted Previous behavior had users posting their trucks more. After launch, carrier were posting less and searching more.
Pushback grew from all carriers Sales and Support heard sustained frustration from our users about how we changed their daily workflow due to our previous design choices
Design joined after Our first job was diagnosis, not defense. The platform was not designed by a team with access to users. The platform was designed with engineering capability at the forfront. Our new design team, had more company influence and leadership support to enhance the UX using research, data and UX principles at our side.

02 · How we diagnosed it

The designs looked fine. Customers’ phones told a different story.

We compared what customers were telling us with how they were actually using the product. The pattern became clear when we looked at their real devices, text settings and search behavior.

Customer conversations

Too much scrolling

Carriers told us they were scrolling constantly and felt like fewer loads were available.

Real-device observation

Enlarged system text

Many customers were older and used larger text settings, making each load card much taller than what we saw in our standard design files.

Behavior data

30+ minute search sessions

Our search-session metric showed users spending more than 30 minutes moving through results trying to find a load. While we don't know for certain if this was because of load quality or our designs, we had assumptions it wasn't load quality because carriers were finding the same loads on web with no complaints of "size".

03 · What customers experienced

Now that we knew it was the design, we needed to figure out what were the true issues.

We designed and reviewed as a team with standard display assumptions. But our research showed carriers used enlarged system text, making cards taller, showing fewer loads and requiring far more scrolling than our files suggested. We looked at our design choices and what could change.

Current Font Size Standard 16px text

Previous designs followed HIG suggestions of a base 16pt font, which allowed 3-4 loads visible on the screen.

Designing for the Right User Broker branding was priority

Our brokers paid a lot for our product. Previous business decisions gave more room to broker name and logos. But our design team influenced a business change to user based products and not favoring one user over the other.

Restoring Density Lots of white space

A brand update changed our product standards to have lots of space, but new research found that our users preferred denser designs, getting more loads and inforamtion at once.

04 · Choosing the right scope

There was a lot of workflow changes that needed to happen with web for the migration. So our mobile team had limited avaiablity to ship anything.

The broader migration pulled development from all teams. So small front-end changes were scoped out to adjust the mobile design.

The evidence for mobile pointed to information density, not a broken search model or navigation like web. Redesigning more than a few small changes would have added engineering, QA, and customer relearning without addressing the simple problem.

This was not about making the UI smaller for aesthetics. It was about restoring scanning efficiency in customers’ real accessibility and system-text settings.

05 · What shipped

More loads. Same screen. Same logic.

We reduced type where appropriate, tightened card height and vertical spacing, and increased what customers could scan at once. Preserving the data, search logic, navigation and information architecture. Providing a solution of only Front-End work and QA with design, not development.

Enlarged text · Lower density Old DAT Mobile load board design with lower information density
Real settings made cards taller and pushed results below the fold.
Corrected · Higher density Updated DAT Mobile load board design with higher information density
The focused adjustment restored scanability without changing behavior.

Once the direction was clear, the changes shipped within a quarter with 1 developer.

06 · Measuring recovery

We built a consistent system of customer sentiment.

During the discovery phases of this tiger team, I helped create and manage monthly mobile CSAT surveys in Stonly, an in-app tool that let us prompt customers without engineering work for every survey. I also helped break down and interpret the feedback.

~58–62% → 76% mobile CSAT initially after migration grew to our target goals of over 70% after redesign
4.5 Stars App Store rating after redesign

Search sessions also shortened meaningfully after the density change, giving us another signal that customers were reaching a load interaction more quickly. It was a directional proxy, not proof that a load was booked.
