Principled, transparent, and well-reasoned architectural decisions
Architectural decisions have lasting impact. They create or constrain future options, influence system qualities, and affect teams' ability to deliver value. Poor decisions compound over time, while good decisions create leverage.
At APPNEURAL, we approach architectural decisions deliberately. We invest time in understanding context, exploring alternatives, evaluating trade-offs, and documenting reasoning. This discipline prevents hasty decisions we'll regret later.
Understanding the problem space, constraints, and requirements
Exploring multiple approaches with their trade-offs
Weighing options against architectural principles and constraints
Recording decisions and reasoning for future reference
Decisions should align with established architectural principles. When principles conflict, make the trade-off explicit and choose based on context.
Support decisions with evidence: benchmarks, prototypes, case studies, or analysis. Reduce guesswork through empirical investigation.
Distinguish reversible from irreversible decisions. Make reversible decisions quickly; invest more time in decisions that are difficult to undo.
Record decisions and reasoning using Architecture Decision Records (ADRs). Future teams need to understand not just what was decided, but why.
We use Architecture Decision Records (ADRs) to document significant decisions:
Architectural decisions benefit from diverse perspectives. We involve:
Those with deep understanding of the problem domain and user needs
Engineers who will implement and maintain the solution
Those responsible for running systems in production
Those affected by the decision's outcomes
