Evan Wiley, Director of Program Management at Pivotal Cloud Foundry (PCF), a major enterprise Platform-as-a-Service (PaaS) provider, describes how more than fifty teams are seen at PCF: We really try to maintain as much contract based, API-based separation of concerns between teams [emphasis added] as we can. We try not to share code bases between teams. All the git repos for a particular team’s feature are wholly owned by that team and if another team is going to make an addition or change to that code base, they’ll either do it with a pull request or through cross-team pairing,
