There are multiple ways to break down a complex task. Each strategy has its strengths depending on the problem structure. Let's explore the three main approaches.

Top-Down Decomposition
Start with the high-level goal and recursively break it into smaller subtasks until atomic
Step 1: Identify Main Goal
"Build mobile app"
Step 2: Break Into Categories
Design → Development → Testing → Deployment
Step 3: Detail Each Category
Design → Wireframes, Mockups, User Testing
✓ Best for: Well-defined goals, clear hierarchies, structured projects

▶Payment Integration
💡 Tip: Each level should have 2-5 subtasks. Too few = under-decomposed, too many = cognitive overload
Decomposition Best Practices
🎯 SMART Subtasks
Specific, Measurable, Achievable, Relevant, Time-bound—each subtask should meet these criteria
⚖️ Balance Granularity
Not too coarse (still overwhelming) or too fine (micromanagement). Aim for 15-30min execution time
🔄 Iterate and Refine
First decomposition is rarely perfect. Adjust as you learn more about the problem
📝 Document Assumptions
Note what you assume about each task—helps when replanning if assumptions prove wrong
