domain-modeling

Domain modeling defines project-specific terms to establish a ubiquitous language for your software design. It improves clarity by challenging terminology upfront and documenting decisions, which reduces confusion and maintains consistent language across your project over time.

To document architectural decisions, record them using Architectural Decision Records. This process captures the reasons and consequences behind each choice for future reference, ensuring that the context of your software design decisions is preserved and maintainable as the project evolves.

The best way to manage project terminology is by creating a central CONTEXT.md file at your project root. This glossary serves as a single source of truth for ubiquitous language, ensuring all team members reference consistent definitions and maintain clarity.

You need to start defining a domain model when beginning a new software project. Defining terms and recording architectural decisions upfront prevents confusion later, ensuring that a consistent ubiquitous language and clear context are maintained from the initial stages of development.

Writing architectural decision records does not slow down development; it enhances it by documenting reasons and consequences for future reference. Recording these decisions alongside your domain model upfront actually reduces future confusion and saves time when onboarding or scaling.
