ADRs #

What are ADRs? #

Architecture Decision Records (ADRs) are documents that capture important architectural decisions made during the course of a project. They are used to document the reasoning behind a particular decision, the alternatives considered, and the consequences of the decision. This structured documentation helps in maintaining a history of decisions, understanding the rationale behind them, and communicating them effectively to the team.

  2. Historical Context: They help in understanding the historical context of decisions.
  3. Consistency: ADRs ensure that decisions are consistently communicated across the team.
  4. Onboarding: They assist new team members in understanding the architectural choices made in the project.
  5. Decision Rationale: ADRs capture the rationale behind decisions, helping in future decision-making processes.
