    Why This Matters

    Understanding the business and technical context helps you make informed decisions rather than blindly following patterns.

    Trade-offs to Consider

    Every architectural decision involves trade-offs. Consider your specific requirements, team expertise, and scale when evaluating options.

    When NOT to Use This

    Knowing when a solution doesn't apply is as valuable as knowing when it does. Consider alternatives for your specific situation.

    Decision Framework

    Use this framework to evaluate whether this approach is right for your use case based on your specific constraints and requirements.
