Functional vs Non-functional Requirements: List & Examples
Precise functional and non-functional requirements are essential to reduce development costs because, when the requirements are clear, the team can develop the project much faster. The difference between functional and non-functional requirements is as follows:
Functional requirements are easy to define because the business idea drives them. They include all the features of your future project and ways users engage with it.
Experience drives Non-functional requirements. In order, to identify them, you need to analyze the product's performance and make it convenient and useful. Such requirements may appear when the product is being used on a regular basis.
In this way, while functional requirements describe what the system does, non-functional requirements describe how the system works.
