Summary

In this chapter, we examined some common reasons why software projects fail. We saw how inaccurate or misinterpreted requirements, architecture (or the lack thereof), and excessive technical debt can get in the way of meeting business goals and success.

We looked at the basic building blocks of DDD, such as domains, subdomains, ubiquitous language, domain models, bounded contexts, and context maps. We also examined why the principles and techniques of DDD are still very much relevant in the modern age of microservices and serverless. You should now be able to appreciate the basic terms of DDD and understand why it is important in today’s context.

In the next chapter, we will take a closer look at the real-world mechanics of DDD. We will delve deeper into the strategic and tactical design elements of DDD and look at how using these can help form the basis for better communication and create more robust designs.
