The subsystem requirements are typically broken down into requirements for several features or services. The specification of the requirements needs to be unambiguous to ensure that all parties involved in the development of the system understand fully what is to be developed and tested. There are two categories of requirements: namely, functional requirements and non-functional requirements. The functional requirements are addressed via the algorithms, and nonfunctional requirements may include hardware or timing requirements.
