Learning by Doing is a methodology that emphasizes acquiring knowledge and skills through practice, experience, and reflection. It posits that genuine learning occurs during the process of action, not merely through theoretical instruction. This approach is particularly suitable for scenarios requiring the transformation of abstract concepts into concrete capabilities, such as skill training, product development, and team collaboration.

API-First Design is a software development methodology that prioritizes designing and defining API interfaces before building applications. By treating APIs as the core product, it fosters team collaboration, enhances development efficiency, and ensures system consistency and scalability. It is suitable for scenarios requiring rapid iteration, parallel development across multiple teams, or building microservices architectures.

A/B Testing is an empirical method that randomly assigns users to different versions (e.g., Version A and Version B) to compare their performance, enabling data-driven decision-making. It is widely used in product optimization, marketing strategies, and user experience improvements, helping teams reduce subjective speculation and validate hypotheses with quantifiable evidence.

The Hook Model is a product framework for designing habit-forming mechanisms, consisting of four cyclical stages: Trigger, Action, Reward, and Investment. It helps products build sustained user engagement by creating behavioral loops, particularly effective for digital products requiring frequent interaction, such as social media, games, and utility apps, enabling teams to systematically design user behavior paths to improve retention and activity.

Event Modeling is a structured approach for designing and building complex software systems by identifying and documenting key events and their relationships within a business domain. It helps teams understand business processes, define system boundaries, and guide technical implementation, emphasizing a business-centric, event-driven perspective to describe system behavior. It is suitable for distributed systems, microservice architectures, or domain-driven design projects requiring clear alignment between business logic and data flow.
