b-i function oriented metrics measuring the following parameters:-
•Number of user inputs:
Each user input that provides distinct application oriented data to the software is counted.
•Number of user outputs:
Each user output that provides application oriented information to the user is counted. In this context output refers to reports, screens, error messages, etc.
•Number of user inquiries:
An inquiry is defined as an on-line input that
Results in the generation of some immediate software response in the form of an on-line output. Each distinct inquiry is counted.
•Number of files:
Each logical master file (i.e., a logical grouping of data that may be one part of a large database or a separate file) is counted.
•Number of external interfaces:
All machine readable interfaces (e.g., data files on storage media) that are used to transmit information to another system.
c-iv A function point extension called feature points, is a superset of the function point measure that can be applied to systems and engineering software applications.The feature point measure accommodates applications in which algorithmic complexity is high. Real-time, process control and embedded software applications tend to have high algorithmic complexity and are therefore amenable to the feature point.
d-ii A function point is a "unit of measurement" to express the amount of business functionality an information system (as a product) provides to a user. Function points are used to compute a functional size measurement (FSM) of software. The cost (in dollars or hours) of a single unit is calculated from past projects.[1]
