How do you write product functions in an srs?

Answer 1

Product functionsThis subsection of the SRS should provide a summary of the major functions

that the software will perform. For example, an SRS for an accounting program

may use this part to address customer account maintenance, customer statement,

and invoice preparation without mentioning the vast amount of detail that each

of those functions requires.

Sometimes the function summary that is necessary for this part can be taken

directly from the section of the higher level specification (if one exists)

that allocates particular functions to the software product. Note that for the

sake of clarity

a)The functions should be organized in a way that makes the list of functions

understandable to the customer or to anyone else reading the document for the

first time.

b)Textual or graphical methods can be used to show the different functions

and their relationships. Such a diagram is not intended to show a design of

a product, but simply shows the logical relationships among variables.
