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.

Mapping out your business’s domain landscape has many benefits: knowledge sharing, generating product ideas, providing the foundation for software architecture, aligning on requirements, but a common challenge is… “where do we start?” The following steps are my baseline format for a series of discovery workshops.

One of the challenges I see regularly is inertia following domain discovery workshops. In companies with many teams and many millions of lines of code, including a lot of legacy, there are endless things that can be improved in the product, software, and organization. Why Thing Get Stuck After Discovery?

Organisations maximising the advantages provided by microservices tend to be organisations which view microservices not just as a technical tool, but a sociotechnical tool.The way software systems are shaped determines the communication paths and the coupling between development teams. As a consequence, we also have subservient teams?

In every workshop, I always ask everyone “Imagine there is no text here. What do you read from the image below, and what might you propose to do next in the workshop? You can do this with almost any visual workshop technique. What is this arrangement of colours and shapes telling you?”.

They need a more loosely coupled architecture and empowered teams. The Warehousing Modernization Enabling Team (an AMET) has been established to guide modernization in the Warehousing domain, which consists of 100+ software engineers and a monolithic codebase. You can also experiment with various workshop formats.

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.

In software, reacting to unforeseen circumstances in real-time is not possible. The gap between defining business requirements and translating them into software needs to be minimised in order to prevent this category of problems. In the software system, we need to decide the business transaction boundaries aka DDD Aggregates.

We will be running a remote-optimised domain-driven design workshop on 15–16th June where we will use some of the techniques discussed in this post and many others, like the bounded context canvas. We can use these to capture outcomes from the workshop aka follow-up actions. In my in-person workshops, I’ve faced this hard limitation.

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.

The value is in talking through the template, discussing each part, and identifying unknowns, conflicts, or other interesting factors that may benefit from additional discussions or potentially workshops.
