How One Platform Team Got 80% Voluntary Adoption by Making the Right Path Easiest

A platform engineering team initially failed to drive adoption of their internal developer platform after six months of top-down development, with almost no teams using it. They rebuilt their approach around a 'paved road' model, letting developers declare infrastructure needs in a single YAML file that auto-provisions repos, databases, monitoring, and Kubernetes namespaces. Rather than mandating the platform, they piloted it with willing teams, iterated on feedback, and let word-of-mouth drive uptake across the organisation. The results were significant: deployment time dropped from two weeks to four hours, change failure rates fell from 18% to 4%, and developer satisfaction scores swung from -10 to +52 NPS. Within six months, 80% of teams had migrated voluntarily, with the remainder accommodated through legitimate exceptions.
