Functional requirements define the specific behaviors and functions a system must perform to meet the user's needs, focusing on what the system should do rather than how it should do it. They serve as a foundation for system design, development, and testing, ensuring that the final product fulfills its intended purpose and user expectations.

Functional requirements

Specific behaviors refer to identifiable actions or patterns of actions that individuals or groups exhibit, which can be observed, measured, and analyzed. Understanding these behaviors is crucial for predicting future actions, modifying undesirable behaviors, and reinforcing positive ones.

Development refers to the process of growth, progress, or evolution in various contexts, such as personal, economic, or social domains. It involves the improvement of conditions, skills, or systems, often measured through indicators like quality of life, education, and economic prosperity.

development

Testing is a critical process in various fields, aimed at evaluating the functionality, performance, and reliability of a product, system, or hypothesis. It involves systematically executing a set of operations under controlled conditions to identify defects and ensure quality assurance before deployment or acceptance.
