# Before → After / 변화 전 → 변화 후 구조

- English name: Before → After
- Korean name: 변화 전 → 변화 후 구조
- Selection category: change
- Use when: Use when the strongest story is a clear before-and-after transformation.
- Avoid when: Avoid when the middle process matters more than the contrast.

## Writing Pattern

**Follow the criteria below to structure the sections**

- Since the narrative contrasts before and after, the core is to show clearly “how things changed.”

**Example narrative flow**

- Why change was needed (the background)
- Before state (problems, limits, constraints)
- After state (results, improvements, reactions)
- Key drivers of the change (how it changed)
- Conclusion or next steps

**Each major section should include**

- Section heading
- Core paragraph purpose (1–2 sentences)
- Phrase messages so the before/after contrast is unmistakable, emphasizing positive effects of the change.
- Describe the before state objectively—even if negative—and present the after state persuasively with quantitative or qualitative results.

## Example Writing Outline

1. **Why Change Was Necessary**: Low engagement and content fatigue made the existing online learning system ineffective.
2. **Before**: The system focused on one-way lectures and achieved only a 35% average completion rate.
3. **After**: Following the introduction of real-time interactive content, completion rose to 68% and satisfaction reached 4.5/5.
4. **Key Drivers of Change**: A full UX overhaul, interactive content, and real-time feedback were the main improvements.
5. **Conclusion and Proposal**: Designing for immersion is the key to better learning outcomes, and we should continue upgrading.

## Writing Notes

- Use data or cases measured on comparable bases for before/after.
- Examples include figures, ratios, reactions, and efficiency.
- For the before state, don’t merely list flaws—explain persuasively why change was needed.
- The after state should demonstrate meaningful progress or value uplift—not just minor improvements.
- Close by answering why this change matters now or what comes next.
