Give two examples of functional and non-functional requirements. Explain your reasons?

Solution

When you are dealing with development of a application or system you need to take care about both Functional and Non Functional requrements.

Functional Requirement mainly deals with what system need to be done. where as Non functional requirement deals with how system performs.

Functional Requirement includes Authorization,Authenticationa and different kind of functionalities (creation, updation, deletion of details). It mainly deals with functionality of system.

We need to check functional requirements like

Login Functionality :

Input : userid, password

Description: checks userid,password. after successful validation allows user to see home page.

Output : Displays Homescreen with success message.

Non Functional Requirement includes Performance, Efficiancy, Accuracy,Reliability, Security,Usability, Scalability, Maintainance.
For a good system measuring non functional requirements is more important.

So functional and non functional requirement is more important to make a well developed system.
