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."
