If there is any one thing any project must have in order not to be doomed to failure, is a collection of both the functional and non-functional requirements. Any project\u2019s requirements need to be well thought out, balanced and clearly understood.<\/strong><\/p>\n

A functional requirement<\/u> is that it essentially\u00a0specifies something the system should do.<\/strong><\/p>\n

Typically, functional requirements will specify a behavior or function, for example:
\n\u201cDisplay the name, total size, available space and format of a flash drive connected to the USB port.<\/p>\n

\"A
A functional requirement for a milk carton would be \u201cability to contain fluid without leaking\u201d<\/figcaption><\/figure>\n

Non-functional requirement<\/u> essentially specifies\u00a0how the system should behave<\/strong>. It also specify the system\u2019s \u2018quality characteristics\u2019 or \u2018quality attributes\u2019.<\/p>\n

\"A
A non-functional requirement for a hard hat might be \u201cmust not break under pressure of less than 10,000 PSI\u201d<\/figcaption><\/figure>\n

Non-functional requirements cover all the remaining requirements which are not covered by the functional requirements.<\/p>\n

Difference: non-functional requirements describe how the system works, while\u00a0functional requirements describe what the system should do.<\/p>\n
