This document discusses a software company's journey to adopting test-driven development (TDD) practices. It describes how the company initially launched its online scheduling system without TDD, which led to problems. A phone call made the company realize it needed to change its development approach to focus on quality. The company then transitioned to using TDD and other quality practices like continuous integration, code reviews, and acceptance testing. The document argues that TDD is not about the tests themselves but about quality, and lists benefits like growing the company and enjoying careers. It encourages readers to educate themselves on TDD, appoint a champion, and support their teams in getting started with these practices.
