There are several techniques available to derive to design your bounded context and domain models. I like to start then with event-storming to focus on the specific part of the system, identify what is happening in your domain. It's usually reflecting a user journey on your water map. From there I apply the tintepologies and specs trying to bring in where are the potential stream of changes that are then reflected by the user needs. And also having the team cognitive load in mind, so components on the further left of water map, they tend to require a high-tech team cognitive load because there's no clear path to action.
“We need to consider our system that we built as sociotechnical systems. The system is more than the sum of its parts. It’s a product of their interactions. We need to focus on improving the performance of the whole, instead of separate parts of the system."
Susanne Kaiser is the author of the upcoming book “Adaptive Systems with Domain-Driven Design, Wardley Mapping, and Team Topologies: Architecture for Flow”. In this episode, Susanne explained how she connected the dots between 3 different methodologies–Wardley Mapping, Domain-Driven Design, and Team Topologies–to design and build adaptive systems for a fast flow of change and why it is important for any organization to have adaptive systems. Susanne went in depth to explain about the Wardley Mapping strategic framework, its five sections, and how they support designing and evolving effective business strategies based on situational awareness and movement following a strategy cycle. She then explained how to translate from a Wardley map into Domain-Driven Design, how DDD helps in applying the Wardley Mapping doctrine principles, before then explaining how Team Topologies helps to create effective team boundaries and optimize team’s cognitive load. Towards the end, Susanne shared from her experience how we can apply this process in our organizations, as well as in legacy systems.
