Non functional requirements examples

Non-functional requirements (NFRs) are specifications about how a system should work, rather than specific behaviors. They are typically related to system performance, security, usability, etc., and are important to consider in order to ensure a robust, user-friendly system. Here are some examples:

  1. Performance Requirements: These relate to how fast the system responds to a user’s actions, the system’s reliability, or how it behaves under heavy loads. For example, “The website should be able to handle 10,000 concurrent users without any degradation in response time,” or “The system should have an uptime of 99.99%.”
  2. Security Requirements: These requirements are crucial for maintaining data safety, to prevent unauthorized access and to ensure compliance with regulations. For example, “All user passwords must be encrypted and stored securely” or “All transactions should be conducted over secure SSL connections.”
  3. Usability Requirements: These requirements are related to how easy the system is to use. For instance, “The system should be intuitive and not require training for new users,” or “All screens should be accessible within three clicks from the home page.”
  4. Scalability Requirements: These requirements dictate how the system should grow over time. For example, “The system should be able to accommodate an increase of up to 50% in user load per year for the next three years.”
  5. Availability Requirements: These refer to the time a system is expected to be operational. For example, “The system should be available for use 24/7, excluding scheduled maintenance periods.”
  6. Maintainability Requirements: These refer to the ease of system maintenance, updates, and modifications. For instance, “The software should adhere to modular architecture to facilitate easy updates and bug fixes.”
  7. Disaster Recovery: These requirements specify the plan for a system in the case of a disaster. For example, “In case of system failure, the system should automatically back up data and recover within 1 hour.”
  8. Legal and Compliance Requirements: These requirements ensure that the system is in compliance with relevant laws, regulations, or standards. For instance, “The system must comply with GDPR and other relevant data privacy regulations.”

It’s crucial to clearly define non-functional requirements in the project planning stages, as they can greatly impact the design and architecture of a system.

What are functional and non functional requirements ?

What are functional and non functional requirements in software engineering? Functional requirements are the specific tasks, constraints, and goals that a software must meet in order to be considered complete. Non-functional requirements are any conditions or attributes of the software that do not directly impact its functionality, such as layout design or user experience. Both types of requirements must be considered when developing a software project. Failure to meet either type of requirement can lead to major issues with the…

What are nonfunctional requirements in software development

What are nonfunctional requirements in software development Nonfunctional requirements (NFRs) are a type of requirement that falls outside of the functionality of a software system. They are typically requirements that are not related to user interaction or system functionality, and instead focus on aspects such as documentation, testing, or quality assurance. NFRs can be divided into two categories: reflectivity and nondiscrimination. Reflectivity refers to the need for a software system to maintain some level of consistency across different implementations. NFRs…
