The Three C's - Card, Conversation, Confirmation - is a foundational concept in Extreme Programming (XP) and Agile methodologies. It refers to a simple and effective approach for managing requirements in software development projects. - **Card:** Represents a user story or requirement written on a physical or digital card. It encapsulates the essence of what the user wants and serves as a tangible reminder of the work to be done. - **Conversation:** Involves ongoing discussions between team members, including developers, testers, and stakeholders, to clarify and expand upon the details of the requirement outlined on the card. This ensures a shared understanding and alignment on the desired outcome. - **Confirmation:** Involves defining specific criteria for acceptance of the requirement, typically in the form of test cases or examples. This helps ensure that the implementation meets the user's needs and is working as intended. The Three C's provide a flexible and collaborative framework for capturing, refining, and validating requirements throughout the software development process, promoting transparency, communication, and customer satisfaction.

The Three C's in Extreme Programming (XP)

Extreme Programming (XP) is an Agile software development methodology known for its focus on flexibility, adaptability, and quick response to changing requirements. Within XP, the Three C's - Card, Conversation, and Confirmation, are fundamental concepts that drive the development process.

Card

Card refers to a physical or virtual representation of a user story or a feature to be developed. These cards are typically small and contain just enough information to describe the desired functionality from the perspective of the end-user or customer.

Conversation

Conversation emphasizes the importance of communication within the development team. Instead of relying solely on detailed documentation, XP promotes continuous discussions between developers, stakeholders, and customers to ensure a shared understanding of the requirements and expectations.

Confirmation

Confirmation focuses on the validation and verification of the implemented functionality. By creating tests based on the user stories or features outlined on the cards, XP ensures that the code meets the specified requirements and functions correctly. These tests serve as a confirmation that the development is progressing in the right direction.
