What is a functional specification?
function specification describes the basic functions of the software application. In general, it develops as part of the software development requirements. It serves as a blue print for programmers to develop source code and test cases for application.
In general, many different players are involved in the requirements analysis for the development of each software application. These players include entrepreneurs who expect to use software, data analysts, programmers and other technical staff. Entrepreneurs explain to other team members exactly what they expect from the software from a business point of view.
Business requirements are merged with the data to be captured and are used to develop the way the team would like each screen to work. To document functioning specifications, the analysis of all these requirements must be completed. Once the functional specification is roughly the documentary was the team to tune it. The team checks these documents and fills in any space in the analysis requirementat. Upon completion of the requirements, the team approves the functional specification. The approved specification document is used as a plan for software development.
Source code and test cases are developed using a functional specification. Team members use a functional specification to develop test cases needed to confirm that the software works as indicated. The number of test cases used to debug software varies based on the complexity of the developed software. As programmers develop software, another part of the team is developing test cases. The software approval process begins as soon as the programmers inform the team that it is ready for testing.
functional specification does not specify such things as a software language to use programmers. Specifications found in a functional specification are limited to actual program functions. A specification document explains what the tent isE, when a program user clicks on a specific button on the screen, but not how the programmer runs a specific function.
Depending on the complexity of the software to be developed, some teams use multiple document levels functional specifications. The management team could participate in a high -level specification, while a group of higher analysts can define in more detail the specific functions and a common team of business analysts and programmers can define each screen. Each of the output documents from these levels can be considered a functional specification.
