DDD - model instead of requirements

  • 40 min

There are many methods to develop requirements (user story, use case and so on), but all of them mainly describe behavioural aspects. But how to work in the sphere of complex business requirements where objects change their behaviour as the context may admit?

Domain-Driven Design (DDD) is an approach that allows to create clear and clean vision of domain area. Ubiquitous language gives ground for communication between customers, analytics, developers, testers and end-users. And we can use models developed in this language instead of traditional requirements, which are used only to build models in this process, and then they lost their actuality. This approach significantly simplifies design process and reduces risks in complex IT-projects enabling business professionals to fully verify Models. And then, while in operation, Models allow to develop and expand software system efficiently for many years following changes of customer’s business processes.
