Functional and non-functional requirements in Software development Essay

Functional and non-functional requirements in Software development - Essay ExampleThis involves the set of actions that clarify what on the nose a particular scheme has to do. On the other hand, non-functional requirements engross the dodging constraints that define how it will do the functional requirements. It acts as a criterion for elaborating the performance of a particular system (Yang, 2010).The functional and non-functional requirements of any system always flummox a huge effect on the development life cycle. To be precise, all through the development life cycle of a system, functional requirements as the main field of study of concern in each phase (Mishra & Mohanty, 2012).Right from the first phase, requirements analysis, to, maintenance phase, functional requirements act as the basis for each phase. That is, each phase, must ensure that the predefined functional requirements satisfy what the user is expected to swallow from the system. In this sense, functional requ irements always define the amount of cadence to be spent in the system development life cycle (Shelly & Rosenblatt, 2012).A crucial example of functional requirements is, adding a new order of battle into a web-based order entry system. This functionality requires a number of key attributes to be defined and they include, order name, its identification, time it was processed among others as stipulated in the requirements analysis phase. Therefore, as soon as this functional requirement is defined, then, passim the development life cycle the developer must ensure that its features are perfectly satisfied until a utmost output product is delivered (Milanovic, 2011).One of the major non-functional requirements is efficiency. As stipulated earlier, non-functional requirements include the constraints that will elaborate how a system is to meet the pre defined functional requirements. To the development life cycle, efficiency depends on the outputs of the functional requirements. In t his sense, non-functional requirements have very little effect
