functional requirements vs non functional requirements
Functional requirements describe what the software system should do in terms of specific functionalities or features. They define the behavior and capabilities of the system.
Examples of functional requirements:
1. The system shall allow users to create an account and log in.
2. The system shall provide a search functionality to allow users to search for products.
3. The system shall allow users to add items to a shopping cart and proceed to checkout.
4. The system shall send email notifications to users upon successful completion of an order.
5. The system shall generate monthly sales reports for the management team.
Non-functional requirements describe the qualities or characteristics of the software system, rather than specific functionalities. They define how well the system performs or behaves in certain aspects.
Examples of non-functional requirements:
1. Performance: The system shall respond to user interactions within 3 seconds.
2. Scalability: The system shall be able to handle a minimum of 1,000 concurrent users without performance degradation.
3. Security: The system shall use encryption to secure user data during transmission and storage.
4. Usability: The system shall have a user-friendly interface with intuitive navigation.
5. Reliability: The system shall have an uptime of at least 99.9% to ensure continuous availability.
In summary, functional requirements define what the software system should do, while non-functional requirements define how the system should perform or behave in terms of various qualities. Both types of requirements are important for the successful development and implementation of a software system.
