Case Study: ASOS boosts development speed and code review efficiency with GitHub Copilot

ASOS ships faster with GitHub, reaching 90% Copilot adoption and 9-day prototyping

ASOS, a London-based fashion e-commerce retailer, faced a challenge in sustaining its rapid development pace. With 700 engineers working across over 3,000 repositories in Azure DevOps, engineers were often slowed down by working in unfamiliar codebases and languages. To empower its developers to ship features faster for its 17 million customers, ASOS partnered with vendor GitHub to unify its codebase and implement AI-powered development tools.

The solution involved migrating all repositories to GitHub's platform and rolling out GitHub Copilot to the engineering team. This provided developers with an AI-powered environment to navigate code and accelerate work. The results were significant, achieving 90% adoption of Copilot. Productivity gains were substantial, including building a tool in 9 days that was estimated to take 2 months. GitHub Copilot Code Review also helped bring pull request first approval times down from a peak of 56 hours.
