: Essential qualities the product must have, such as: Usability : How easy it is to learn and use. Performance : Speed, capacity, and reliability. Security : Protection against unauthorized access. Look & Feel : The desired aesthetic and spirit.

: Focus on external events that trigger a response from the business (e.g., "Patient books appointment").

: A specific measurement that tells you if a delivered solution "fits" the requirement (e.g., "The system shall respond within 2 seconds for 95% of queries").
