At Intercom, they employ a concept called "engineering tours" to spread engineering knowledge and culture across different teams. This involves temporary transfers of engineers to other teams to work on specific projects, allowing them to gain impact while still onboarding. The goal is to break down silos and facilitate cross-team relationships, promoting constant learning and growth. Engineering tours are not just about code reviews but also about building relationships and forging friendships across the organization. This approach has been successful in knowledge and culture sharing, even as Intercom grows with multiple offices. By adopting this model, other engineering organizations can benefit from enhanced employee engagement, cultural health, and ongoing challenge.
