Answer 1

Solution for Question 2:

Functional Requirements for any system defines what a system should do (ie. the functionality/features of the particular system), while on the other hand Non-Functional Requirements defines how well a system does(performs) what its intended to do.

For an in-store supermarket self-service checkout system, the functional and non-functional requirements are as follows:

Functional Requirements:

• Self-service checkout system should be friendly and provide the user with a complete guided path for checkout. (ie. it should be easy to navigate through).
• It should accurately scan the product/items, and display the correct prices on the monitor/screen.

Non-Functional Requirements:

• Minimizing checkout time or Minimizing the amount of user clicks/interaction with the self-service checkout system.
• User Interface of the system should be engaging, attractive and responsive.
