PBX

Empty backlog
thanks to PBX test builds
Minutes only
to build variants on the live site
Rapid prototyes
for "complex functionality" variants
At a glance...
- Fossil Group unblocked a years-long backlog by clearing “easy” and “medium” testing ideas stalled by developer bottlenecks.
- Using PBX, Fossil Group builds variants on their live site in minutes, improving ease of access to testing with real users.
- This leads to scalable innovation that maintains statistical significance on all experimentation.
Fossil Group is a global powerhouse in the world of e-commerce. The U.S.-based company designs and manufactures watches, leather goods, jewelry, and accessories both through its own brands and licensed watches for brands like Michael Kors, Armani Exchange, and BMW.
Their impressive reach shows in their testing: they run over 100 tests every year to expedite learnings in an agile environment. And yet, even in this environment, experimentation velocity is still frequently bottlenecked by development capacity.
High-value ideas would sit in the backlog for months at a time, because they required hours of developer time that simply weren't available.
The solution: Prompt-based Experimentation
Fossil Group had been a Kameleoon customer since 2023, so they had access to Prompt-based Experimentation (PBX) as soon as it became available. They integrated PBX into their agile sprint process to bypass their bottleneck by empowering analysts to build front-end variants directly onto their live site using natural language prompts.

Fossil used PBX to clear long-standing items from their backlog that were not previously prioritized:

A culture of “show and tell”
Adopting PBX means Fossil’s experimentation culture evolves to embrace a leaner, faster approach to ideating, building, and launching variants.
Increased Velocity
Fossil Group’s backlog of experiments shifts to “easy” ideas that analysts can launch quickly with PBX without needing to wait for a dev sprint.
Enhanced Rigor
Fossil maintains a 95% statistical significance threshold, ensuring that increased speed never compromises data integrity.
Collaborative Governance
PBX allows UX and brand teams to provide feedback on existing variants without needing to add them into their workflow, increasing collaboration without increasing workloads.

Prompt-Based Experimentation
“We had a simple idea in our filters: show a color swatch next to the text. It’s an easy UI improvement literally just adding color to the label. Everyone agreed it made sense, but it sat in our backlog for over a year and never got prioritized. With a simple prompt, we created it instantly.”

“PBX has done a tremendous job to alleviate dev work and to bring ideas that used to take many, many hours before down to easy.”
