At a Glance

Challenge

How could DEPT® roll out GitHub Copilot at speed and scale and stay competitive in an AI-driven market? 

Solution

Migrate to GitHub Enterprise and implement Xebia's GitHub Copilot Adoption Framework.  

Results

One developer platform, GitHub Copilot, and teams trained to use it effectively in daily workflows. 

The Challenge: "The industry is asking for AI" 

Following multiple acquisitions, DEPT®’s development teams were spread across different tools for managing, collaborating on, and deploying code. To bring everything together, the agency partnered with Xebia and migrated to GitHub. Wesley Niels, Director Cloud EMEA at DEPT ®, adds: “With everyone on one platform, we get better knowledge sharing, clearer reporting, and one unified strategy instead of scattered requests.” 

Moving to GitHub also set the stage for the adoption of GitHub Copilot. “In our industry, the pressure to embrace AI is on. Agencies are already losing deals simply because they haven’t adopted it,” says Niels. He continues, “We are familiar with AI, and chose GitHub Copilot to add extra firepower to our AI-driven workflows, making it our primary coding assistant.” 

With hundreds of developers worldwide, DEPT ® turned to Xebia to roll out GitHub Copilot at scale, measure and maximize its impact from day one, and embed it into existing workflows without disruption. 

The Solution: "One platform, powered by AI"  

After consolidating multiple platforms onto GitHub Enterprise Cloud, Xebia turned to laying the groundwork for GitHub Copilot — beginning with onboarding DEPT® to its Managed Developer Platform to simplify license distribution and management. Jesse Houwing, Microsoft & GitHub Trainer at Xebia: "Since GitHub Copilot is now the agency’s default coding assistant tool, every GitHub user automatically receives a license. Activation happens through single sign-on, licenses are automatically revoked when employees leave, and costs are allocated by department and country."  

Xebia and DEPT® then kicked off Xebia's GitHub Copilot Adoption Framework, which includes: 

  • Training a core group of GitHub Copilot Champions: Go-to-advocates that support peers locally and ensure scalable, rapid enablement.  
  • Webinars:  The GitHub Copilot Champions are now developing and delivering webinars to bring specific knowledge and skills to the rest of the teams. 
  • Ongoing learning support: Xebia provides exclusive content, including video tutorials and feature updates, which are regularly shared via DEPT®'s Slack channels. 
  • GitHub Copilot Hackathon: A proven, collaborative format that allows participants to experiment with real-world applications. 

Beyond teaching people how to work with the technology, Xebia also serves as a strategic partner for DEPT®. Max Verhorst, EMEA Sales Leader Microsoft/GitHub at Xebia, adds: “This is where it gets exciting, and our expertise really comes into its own. Because what happens when you start working with AI? Will you work faster? How much faster? What new things will you be able to do that weren’t possible before? And how might AI change your operating model? These are the type of questions we explore together with our clients." 

The Outcome: "The technology and skills to win with AI"   

  • One Platform: DEPT® migrated from Bitbucket, Azure DevOps, and GitLab to a single, secure and well-configured GitHub environment. 
  • GitHub Governance: Xebia implemented full GitHub Copilot governance, including user management, license control, and cost tracking. 
  • Global Enablement: Developers are fully trained and confident using GitHub Copilot across teams worldwide. 
  • Maximize AI Value: Xebia provides ongoing support and insights on AI impact and GitHub Copilot ROI across the organization. 

“Xebia has been an incredible partner throughout our migration and consolidation to GitHub Enterprise. Their expertise and hands-on support ensured a smooth transition for all our teams worldwide. On top of that, their guidance in enabling GitHub Copilot across DEPT® has helped us accelerate development and unlock new levels of efficiency and creativity in our engineering practices. Without Xebia, we wouldn’t have been able to finalize the migration as quickly and seamlessly as we did.”
