Okay, I need to create a Wikipedia-style document about the 7P model in service marketing under the categories of Economics, Market and Business, and Service Marketing. Let me start by understanding what the user is asking for.

First, the structure: H1 title, overview section, several sections with H2 and H3 headings, and references or related documents if needed. The content needs to be accurate, objective, detailed enough, easy to read, and use professional terms with explanations. Also, markdown formatting with proper hierarchy, lists, tables, emphasis, and code blocks where necessary. The document should be at least 800 characters long.

Starting with the title: "7P" as per the user's request. Then an overview section explaining what 7P is, its origin, and significance in service marketing. Next, I need to break down each of the 7Ps into H2 sections. Each P should have a sub-section (H3) for definition, importance, examples, and challenges.

Wait, the user mentioned "소분류: 서비스 마케팅" so it's specifically about service marketing. The original 4P model is extended to 7P in services. I need to explain why that extension happened. Maybe start with an overview of the 7P model, then each P.

For each P (Product, Price, Place, Promotion, People, Process, Physical Evidence), I should define them, their importance, examples, and challenges. Also, maybe a section on how they differ from the original 4Ps.

I need to make sure that technical terms are explained. For example, "Physical Evidence" might not be as intuitive for some readers. Including real-world examples would help. Maybe use bullet points or tables where appropriate.

Check if there's any specific information about the 7P model that's crucial. The original 4Ps were extended by Booms and Bitner in 1981, so I should mention that. Also, note that 7P is more applicable to service industries because of their unique characteristics like intangibility, perishability, etc.

I need to ensure the document flows logically: introduction, each P with sub-sections, maybe a comparison between 4P and 7P, and then conclusion or references. Wait, the user mentioned "참고 자료나 관련 문서" so I should include some references at the end.

Let me outline:

1. H1: 7P
2. Overview/Introduction (what is 7P, origin, purpose)
3. Sections for each P:
4. Product
5. Price
6. Place
7. Promotion
8. People
9. Process
10. Physical Evidence
11. Maybe a section on the differences between 4P and 7P
12. Conclusion or summary
13. References

Each P section should have H2, then H3 for definition, importance, examples, challenges.

Wait, but the user said "상세 내용을 담은 여러 섹션 (H2, H3 활용)" so maybe each P is an H2, and within that, H3s like Definition, Importance, Examples, Challenges. But I need to check if that's necessary or if it's better to have a single section per P with subpoints.

Also, the user wants at least 800 characters. The example response they provided earlier was around 1500 words, so I need to make sure mine is sufficiently detailed.

I should start drafting each part step by step, ensuring that all points are covered and the structure is correct. Use markdown syntax for headings, lists, etc. Avoid any markdown in the thinking process but ensure it's applied correctly in the final answer.
