TDD Helps You Scale Without Slowing Down

Your specs are sharper, your team’s performing better, and your system is more reliable than ever. Besides that, what else does TDD buy you?

In a word: scale.

How does TDD let you scale? Simple — it lets you hire more people, often at lower cost, while keeping your system and process stable as the team grows.

The most common cost as you scale is due to communication overhead. TDD builds communication into your system, greatly reducing that cost.

TDD gives you the structure to let a junior developer work in the codebase without the risk of them shooting themselves in the foot. It lets them contribute meaningfully without constant oversight from a senior.

That’s how TDD helps you grow your team without slowing you down.
