Why it works

The before-state is concrete: web and backend A/B testing simply did not exist, making this a genuine New Capability story rather than a speed improvement on something they already did. The quotes from two named executives carry specific detail about the mechanism, particularly the Datadog overlay for correlating flag activations with performance degradation. The story is close to a coin-flip with Efficiency, since streamlining is a constant theme, but the lead problem is capability absence, not slowness.

Steal this

Use two named executives at different levels (Head of Product Analytics and VP of Engineering) to cover both the data workflow pain and the developer experience gain, giving the story two distinct credible voices without requiring separate case studies.
