Source: Dell Carnegie's speech method or learn from various structured thinking methods

Original design intention: 1) Express clear logic quickly: Through a concise and powerful structure, listeners or readers can quickly grasp key information; 2) Improve persuasion: Strengthen the credibility and influence of opinions through reasons and examples; 3) Adapt to various scenarios: it can be used in scenarios such as writing, speech, debate, etc., providing a method that is easy to remember and implement.

P(Point-view): clearly express the core point of view so that the audience or readers can quickly understand the topic. Summarize the core conclusions in one sentence and avoid vague expressions.

R (Reason-Reason): Provide reason or support for your point of view. Data-based expression (such as "efficiency improvement of 30%" is better than "significant improvement"); logical chain is complete (reason-deduction-conclusion).

E(Example-Example): Strengthen the persuasiveness of the point of view through specific examples or data. Select audience-related examples (such as technical cases for technical scenarios); quantify results to enhance credibility.

P(Point-Reiterate Viewpoint): Go back to the point of view, briefly summarize and emphasize the importance. Recommendations of action or call for decision-making.

In the absence of sufficient time, it can be reduced to P (only concludes) or PRP (not giving examples).

Advantages: 1) Clear structure and reduce the cost of understanding; 2) Enhance persuasion (combination of logic and facts); 3) Applicable to rapid decision-making scenarios.

Applicable scenarios: 1) Efficient communication (report, speech, writing); 2) Logical expression (avoid length and highlight key points); 3) Problem analysis and solution design. P.S.1) It is not recommended to use it in an environment where people criticize others by talking about things; 2) It is not recommended to use it in an environment where people put forward the opposite viewpoint.

Business decision-making: Use PREP to convince investors (view-data support-success stories-conclusion)

Education and training: Course design: throw out knowledge points - explain the principles - give examples - summarize key points

Daily communication: Work report: Conclusion first-conclusion is concise - data support - reaffirming the needs

Product design: User demand document: Functional value - User pain points - Competitive product comparison - Solution priority

Cross-departmental collaboration: Resource application: Objectives - Necessity - Past Cooperation Results - Expected Support

Digital technology field: Case: Technical plan report. P: Adopting a microservice architecture can improve system scalability. R: Containerized deployment supports elastic scaling, and module decoupling reduces maintenance costs. E: The failure rate of a certain financial system has dropped by 60% after its transformation. P: Microservices are the key technical path for digital transformation.

大数据分析：案例：数据报告撰写。 P: The user churn rate is strongly correlated with the page loading speed; R: The A/B test shows that the user churn rate with a loading time > 3 seconds increased by 40%; E: After optimizing the loading speed of a certain e-commerce APP, the retention rate increased by 15%; P : Performance optimization should be the core strategy for user growth.

Artificial Intelligence: Case: Report on the effectiveness of AI model. P: The introduction of the Transformer model significantly improves the accuracy of NLP tasks; R: The self-attention mechanism solves the problem of long sequence dependence; E: In text classification tasks, the F1 value increased from 85% to 92%; P: The Transformer architecture is the current NLP The best choice for the field.
