CHAPTER 7 Choose specific team interaction modes to enhance software delivery. Choose between three team interaction modes—collaboration, X-as-a-Service, and facilitating—to help teams provide and evolve services to other teams. Collaboration can be a powerful driver for innovation but can also reduce flow. X-as-a-Service can help other teams deliver quickly but only if the boundary is suitable. Facilitating helps to avoid cross-team challenges and detects problems.
