We can learn a few things from these examples. For example, an industry is a domain where domain concepts are grouped based on commercial endeavour like the ride sharing industry. I encounter this problem quite frequently when the word domain is used in the context of business and software architecture. Meso Domain ?—?an

Typically, there’s a period where modernization is discussed as the pains of legacy systems and/or ways of working are noticed and become ever more prominent, blocking the business strategy. In our example, we named the “Warehousing Modernization Enabling Team”, articulating their scope and enabling focus.

The microservices era has been good for software architecture. A domain service builds on the basic definition of a microservice: it’s a loosely-coupled, independently deployable element of software architecture which is owned by a single team. I remember when the idea of multiple databases was punishable by death.

If you would like to learn or practice how to break up a large business into domains and use them as the foundation for your software architecture and team organization, I have created a strategic domain-driven design kata that you may find useful. Domain message flow modelling is used for this step.

I’ve been disappointed for a long time with the way in which companies organise software development teams. I remember as a young, naive software developer, I assumed there would be structured processes and patterns similar to those used for designing a software architecture. A clear warning sign.

Domain-Driven Design is an approach to designing systems, usually software, that emphasises creating a common language between domain experts and system builders. Here’s an example I use in talks and workshops: How to group these concepts into domains? The elements in Simon Wardley’s Strategy cycle are much more usable in my opinion.

It seems unrealistic wanting the best of both world (speed and reliability) but the field of software engineering established during the past decade that speed and reliability can both be achieved. Moving from a single to multiple products can be one of those situations where architecture starts to get in the way.

There are thousands of ways we can shape the software systems we build and organise our teams around them. The products themselves are software systems which grow harder and harder to reason about as they scale and age. Lack of accountability leads to unmaintainable software that grows harder and harder to change.
