Use Ubiquitous Language To Create The Right Product

The Ubiquitous Language (UL) is a strategic pattern 🧩 coming with Domain-Driven Design (DDD). It aims to align people’s β€” all stakeholders β€” understanding regarding the business domain(s) implied. πŸ‘¨β€πŸ’ΌπŸ‘©β€πŸ’Ό

For instance, the business analyst could use the term “User” πŸ§‘, the marketing person “Customer”, and the developer “Client” β€” all talking about the same thing!

And you know β€” ultimatelyβ€” the final product is based on the developer’s understanding. πŸ’»

Having a Ubiquitous Language will help to tackle any misunderstanding. Discovering or defining your Ubiquitous Language could be challenging and requires domain experts πŸ•΅οΈ around to make the “rich domain model” clear to everyone.

Once identified, it should be used by everybody, from everywhere β€” marketing documents πŸ“„, code (classes, events, etc.), user interface and any communication.

Furthermore, be clear, sometimes the same term can be used in two different contexts (domain/bounded) but with different meanings. From the code perspective, it should be distinct “entities” living in their context. ❗️

Workshops like EventStorming 🌩️, could help identify your Ubiquitous Language and more with other DDD strategic patterns β€” it will soon be a post on my blog. πŸ“

Don’t forget clear communication πŸ—¨οΈ is often the key to any collaborative project.

Does the domain drive your developments?
