The Complete Evaluation Framework

Now you have the complete 4-Step System Design Evaluation Framework :

✅ Step 1: Component Breakdown

• [ ] System is broken into meaningful components
• [ ] Each component has a clear purpose
• [ ] Not just one giant black box

✅ Step 2: Clear Responsibilities

• [ ] Each component has specific responsibilities
• [ ] Responsibilities don't overlap
• [ ] No confusion about "who does what"

✅ Step 3: Technical Details

• [ ] Database & caching strategy defined
• [ ] Scaling & fault tolerance planned
• [ ] Asynchronous processing identified
• [ ] Communication protocols chosen

✅ Step 4: Individual Resilience

• [ ] Each component can scale independently
• [ ] Fault tolerance mechanisms in place
• [ ] No single points of failure
• [ ] High availability maintained

Key Insight: "Use this framework for every system you design - it transforms random architecture into thoughtful engineering."
