Functional vs Non-Functional Requirements: what is the difference [Ultimate Guide with Examples]

Once you have an idea for a future product, the next step in its implementation is to create a list of product requirements. Mandatory requirements include business requirements, user requirements, functional and non-functional requirements, and implementation requirements.

Functional and non-functional requirements are paramount. The first ones determine how the system should function, what additional software should be integrated, what access levels are set, they determine rules for storing and processing data, and much more.

On the other hand, non-functional requirements view the system from the user's point of view; they describe the attributes of the system (color, quantity, quality).

Each of these two types of requirements is vital to the product you are to develop. The more precisely the requirements are described at the very beginning of your development path, the more chances you have to create a quality product the first time while saving your budget and gaining time from competitors.
