# Think — Problem Solving & Analysis (English)

> Structured thinking processes for complex problems

---

## Problem-Solving Approaches

### 1. Divide & Conquer

```
Problem -> Sub-problems -> Solve individually -> Combine
```

### 2. Root Cause Analysis

```
Symptom -> Why? -> Why? -> Why? -> Root cause -> Solution
```

### 3. Constraint Relaxation

```
Unsolvable problem -> Relax constraints -> Solve -> Re-apply constraints
```

### 4. Analogy Search

```
New problem -> Similar known problem -> Adapt solution
```

---

## Analysis Methods

| Method | Application |
|--------|-------------|
| **SWOT** | Strengths/Weaknesses/Opportunities/Threats |
| **Pro/Con** | Decision making |
| **Pareto** | 80/20 prioritization |
| **Fishbone** | Root cause analysis |

---

## Decision Heuristics

### Under Uncertainty

```
1. What is the worst-case scenario?
2. Is it reversible?
3. What is the cost of inaction?
```

### Under Complexity

```
1. What is the simplest first step?
2. What would an expert do?
3. What would the 80% solution be?
```
