Large organizations adopting Scala need to make their teams productive quickly. And they need to do this repeatedly.
Underscore helped them succeed with a combination of training and team support. Our Embedded Team Mentoring service works by first training the team in the core skills they need. Then, we spend a few days a week with the team as they implement a business feature. We review progress, code commits, and give break-out sessions on topics that need further exploration.
This is how companies like YOOX NET-A-PORTER GROUP can take a team and fast track them to delivering good quality working code.
