Okay, I need to create a Wikipedia-style document in markdown format based on the given categories and keywords. The main topic is "Product" under the subcategory of Marketing Strategy within Economics and Business Markets. Let me start by understanding the requirements.

First, the structure: H1 for the title, an overview section, several sections with H2 and H3 headings, and possibly references or related documents. 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 if needed. The document should be at least 800 characters long.

Starting with the title: "Product" as H1. Then an introduction that defines what a product is in marketing context. Next sections could include definitions, types of products, product life cycle, product positioning, and maybe examples or case studies. Each section needs to have subheadings (H2) and possibly further subsections (H3).

I should make sure each part is informative. For example, under "Product Definition," explain the concept, then move to different types like goods, services, digital products. Then discuss the product life cycle stages: introduction, growth, maturity, decline. Product positioning could cover how companies position their products in the market. Maybe include a section on product strategy elements like branding, pricing, distribution.

Need to check for technical terms and explain them if necessary. For instance, when talking about the product life cycle, define each stage briefly. Also, use examples to illustrate points, maybe mention real-world cases like Apple's iPhone or Coca-Cola's brand positioning.

I should avoid being too verbose but ensure enough depth. Each section needs to be concise yet informative. Maybe include a table comparing different types of products or a diagram of the product life cycle, but since it's markdown, I can use text-based tables. Also, check for any relevant references or related documents, like links to other marketing strategies or theories.

Wait, the user mentioned "필요시 참고 자료나 관련 문서 섹션" so maybe add a section at the end with references or further reading. But since it's a wiki-style document, perhaps just list some key sources or related topics.

Make sure the language is clear and straightforward. Avoid jargon unless explained. For example, when discussing product positioning, explain that it's about how a product is perceived in the market relative to competitors.

Check for the length: 800 characters minimum. The initial draft should be longer than that. Let me outline each section with bullet points first:

1. Title (H1)
2. Introduction/Overview
3. Product Definition and Importance
4. H2: What is a Product?
5. H3: Core Components of a Product
6. Types of Products
7. H2: Classification by Nature
8. H3: Goods vs Services
9. H3: Digital Products
10. Product Life Cycle
11. H2: Stages and Strategies
12. H3: Introduction Stage
13. H3: Growth Stage
14. H3: Maturity Stage
15. H3: Decline Stage
16. Product Positioning Strategy
17. H2: Definition and Importance
18. H3: Key Elements (Branding, Target Audience)
19. Case Studies or Examples
20. H2: Real-World Applications
21. Conclusion
22. References/Related Documents

Now, expand each section with content. Ensure that each part is detailed enough. For example, under Product Definition, explain the 4Ps of marketing and how product fits into it. In Types of Products, give examples like physical goods (cars), services (banking), digital products (software).

For the Life Cycle, describe each stage's characteristics and strategies companies use. In Positioning, discuss differentiation and targeting. Use bullet points or lists where appropriate.

Check for technical terms: "Product life cycle" is a standard term, but explain it briefly. Maybe mention that it's a concept used to manage product development and marketing strategies over time.

Avoid markdown code blocks unless necessary. Since the topic is about marketing strategy, maybe not needed here. Use tables if comparing different product types or stages.

Finally, ensure the document flows logically from introduction to detailed sections, then conclusion. Keep paragraphs short for readability. Check that all requirements are met: structure, content quality, formatting, length.
