Functional requirements are statements that describe what a function or system is supposed to do. They are used to define the behavior of a system and to ensure that it meets the needs of its users. Template functional requirements examples can be helpful for understanding the different types of functional requirements and how to write them.
There are many different types of functional requirements, but some of the most common include:
Input Requirements
Input requirements define the data that a function or system accepts. They can include the data type, format, and range of acceptable values. For example, a function that calculates the area of a rectangle might have an input requirement for the length and width of the rectangle. Input requirements are important for ensuring that a function or system can process the data that it needs.
Output requirements define the data that a function or system produces. They can include the data type, format, and range of acceptable values. For example, a function that calculates the area of a rectangle might have an output requirement for the area of the rectangle. Output requirements are important for ensuring that a function or system produces the data that its users need.
Processing requirements define the operations that a function or system performs on data. They can include calculations, comparisons, and other types of operations. For example, a function that calculates the area of a rectangle might have a processing requirement to multiply the length of the rectangle by the width of the rectangle. Processing requirements are important for ensuring that a function or system performs the operations that its users need.
Performance requirements define the speed, accuracy, and reliability of a function or system. They can include the response time, error rate, and availability of the function or system. For example, a function that calculates the area of a rectangle might have a performance requirement to calculate the area within a specified amount of time. Performance requirements are important for ensuring that a function or system meets the needs of its users.
Quality Attributes Requirements
Quality attributes requirements define the non-functional requirements of a function or system. They can include security, usability, maintainability, and other quality attributes. For example, a function that calculates the area of a rectangle might have a quality attribute requirement for the security of the data that it processes. Quality attributes requirements are important for ensuring that a function or system meets the needs of its users.
