Kaizen

## Overview Small improvements, continuously. Error-proof by design. Follow what works. Build only what's needed. **Core principle:** Many small improvements beat one big change. Prevent errors at design time, not with fixes. ## When to Use **Always applied for:** - Code implementation and refactoring - Architecture and design decisions - Process and workflow improvements - Error handling and validation **Philosophy:** Quality through incremental progress and prevention, not perfection through massive effort. ## The Four Pillars ### 1. Continuous Improvement (Kaizen) Small, frequent improvements compound into major gains. #### Principles **Incremental over revolutionary:** - Make smallest viable change that improves quality - One improvement at a time - Verify each change before next - Build momentum through small wins **Always leave code better:** - Fix small issues as you encounter them - Refactor while you work (within scope) - Update outdated comments - Remove dead code when you see it **Iterative refinement:** - First version: make it work - Second pass: make it clear - Third pass: make it efficient - Don't try all three at once ```typescript // Iteration 1: Make it work const calculateTotal = (items: Item[]) => { let total = 0; for (let i = 0; i { return items.reduce((total, item) => { return total + (item.price \* item.quantity); }, 0); }; // Iteration 3: Make it robust (add validation) const calculateTotal = (items: Item[]): number => { if (!items?.length) return 0; return items.reduce((total, item) => {
