what is functional  and technical requirements means information technology
Information Technology (IT) Requirements Definition. Wanting new software is not the same as needing new software. Before undertaking a new software evaluation process, a well documented list of requirements can help clarify exactly which product best meets your needs and why. In order to determine needs, establish 10 -15 primary requirements per application area as a reasonable starting point.
However, what exactly is the difference between âfunctionalâ and ânon functionalâ requirements? Itâs not that complex, and once you understand the difference, the definition will be clear. The official definition of âa functional requirementâ is that it essentially specifies something the system should do.
Ideally, the technical requirements should give an insight as to what is being required basically from the client. More of the technical stuff just makes the requirement a constraint over the system. Most of the technical requirements can be converted to functional requirements by very good questioning.
