Why it works

The case study earns its Efficiency tag through a concrete, memorable metric: 75% less code to ship a notification. The before-state is vivid, a one-word copy change requiring an engineer, a code review, and days of delay, which makes the payoff feel real and relatable to any ops-heavy company. The secondary Breakthrough tag reflects the 10x headcount growth framing, but the piece leads with time and effort savings rather than growth numbers, so Efficiency wins the tie-break.

Steal this

The specific, small-stakes before-state example (changing one word in a header taking days) makes an abstract efficiency argument concrete and emotionally resonant for any reader who has lived that frustration.
