Commonly Used Methodologies by Development Teams

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.

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.

Event Storming is a collaborative modeling method that visualizes domain events in business processes to help teams quickly understand complex systems, identify key issues, and design solutions. It emphasizes cross-functional participation, using tools like sticky notes on large walls to build event flows, fostering communication and consensus.

User Story Mapping is an Agile visualization tool that arranges user needs horizontally by user activities and vertically by priority, helping teams understand product value holistically and plan iterations effectively.
