Functional vs Non Functional Requirements Quiz

Functional requirements specify the actions or functions a system must perform to meet user needs and achieve its intended purpose. They define specific behaviors, features, and operations that the system must support, ensuring that it fulfills its role effectively and meets stakeholder expectations.

Non-functional requirements specify how a system performs its functions rather than what functions it performs. The example "System must process 1000 transactions per second" defines a performance benchmark that the system must meet, focusing on efficiency and speed rather than a specific user interaction or feature.

Non-functional requirements focus on how a system performs its functions rather than what functions it performs. They encompass quality attributes such as performance, security, usability, and reliability, ensuring that the system meets certain standards and user expectations, rather than detailing specific user actions or features.

A functional requirement defines specific behaviors or functions of a system. In an e-commerce website, allowing customers to add products to a shopping cart is essential for enabling transactions and enhancing user experience, making it a fundamental functional requirement. Other options relate to performance, security, or usability, which are non-functional requirements.

Functional requirements specify what a system should do, detailing the specific behaviors and functions it must exhibit. In contrast, performance characteristics, such as efficiency and speed, are covered by non-functional requirements. Therefore, the statement incorrectly associates functional requirements with performance, making it false.

Functional requirements outline the specific behaviors and functions a system must exhibit, detailing what the system should do to meet user needs. This includes features, capabilities, and interactions, distinguishing them from non-functional requirements that address performance, security, and user satisfaction metrics.

Non-functional requirements focus on how a system operates rather than what it does. They encompass aspects such as performance, reliability, scalability, and security, which define the system's quality and constraints. These requirements ensure that the system meets user expectations and performs effectively under various conditions.

Non-functional requirements, such as performance, security, and usability, are crucial for the overall quality and user satisfaction of a system. They complement functional requirements by ensuring that the system not only performs its intended tasks but also meets essential criteria for reliability and efficiency, making both types equally important in software development.

Functional requirements outline what a system should do, detailing its specific behaviors and functionalities. They describe the expected interactions, processes, and outputs that the system must deliver, ensuring it meets user needs and performs its intended tasks effectively.

A requirement specifying system availability at 99.9% is non-functional because it pertains to the system's performance and reliability rather than specific behaviors or functionalities. Non-functional requirements define how a system operates, focusing on aspects like performance, security, and scalability, rather than what the system does.

Performance, reliability, and usability are aspects that define how a system performs its functions rather than what functions it performs. These attributes are categorized as non-functional requirements because they specify the quality and constraints of the system, influencing user satisfaction and overall system effectiveness.

A requirement stating that "System must encrypt all passwords" focuses on how the system should perform rather than what it should do. It addresses security and performance attributes, which are characteristics of non-functional requirements. These requirements define criteria for the operation of a system, rather than specific behaviors or functions.
