Mechatronics - Functional and Non-functional requirements

What are functional requirements?

• Requirements that define the quality attributes of a software system

• Requirements that specify what the software system should do

• Requirements that are not mandatory

• Requirements that are captured as a quality attribute

Who typically specifies non-functional requirements?

• End users

• Technical people such as architects and developers

• Project managers

• Marketing teams

Which of the following is an example of a functional requirement?

• Emails should be sent with a latency of no greater than 12 hours

• The site should load in 3 seconds when the number of simultaneous users is >10000

• Authentication of the user whenever he/she logs into the system

• The processing of each request should be done within 10 seconds

What type of testing is associated with verifying the functionality of the software?

• Performance testing

• Stress testing

• Functional testing

• Usability testing

Which of the following is NOT a non-functional requirement?

• Portability

• Security

• System shutdown in case of a cyber attack

• Scalability

How are functional requirements usually captured?

• As a quality attribute

• In use cases

• Through performance metrics

• In system architecture

What is the main difference between functional and non-functional requirements?

• Functional requirements are specified by technical people, while non-functional requirements are specified by users

• Functional requirements are mandatory, while non-functional requirements are not

• Functional requirements are captured as quality attributes, while non-functional requirements are captured in use cases

• Functional requirements define the quality attributes of a system, while non-functional requirements define what the system should do
