The Promise and Challenges of Loose Coupling

APIs should be built around the idea of loose coupling – that providers and consumers of services possess more independence and autonomy to evolve. The obvious advantage of this approach is that it requires less time-consuming coordination, and thus allows providers and consumers to evolve independently.

However, independent growth presents an increased risk of breaking changes. Will existing API consumers have to adapt to every development? Or can they continue using the API in an unaltered state?
