As developers, we understand that our purpose is to deliver value to the business, ; what often eludes us is how to understand the business and where we can be of most value. Domain Driven Design (DDD) and Enterprise Architecture are two different attempts at getting to this understanding.

Enterprise Architecture has the possibility to guide the development of our big enterprise software portfolio in the right direction. Connecting the existing IT portfolio to the business functions and using this as a map to guide future development.

Enterprise Architecture (at least the way we employ it) is an exercise in understanding how the business functions are organized (business capabilities), what information the business is working with, and what IT applications are used to support this.

Domain Driven Design employs Strategic Design as a way to analyze the business domain and organize it into different context to provide some guidance on how to organize the software under development.

We have in the last few years seen a kind of resurgence in the use of Domain Driven Design in relations with to how you should design your microservice architectures. There has have been, and still isare, a lot of discussions around the link between the strategic design promoted by DDD, in particular the Bounded Contexts, and Microservices.

The central idea in this talk is to show how the Business Capability model from Enterprise architecture is closely related to the Bounded contexts Contexts of DDD and thus to Microservices.
