Function point

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.

(FP) is an element of software development which helps to approximate the cost of development early in the process. It may measures functionality from user’s point of view. Counting Function Point (FP):

What is a function point in project management?

  • A function point is a unit of measurement used to express the amount of business functionality an information system provides to a user. The cost (in dollars or hours) of a single unit is calculated from past projects. Function points are the units of measure used by the IFPUG Functional Size Measurement Method.

What are function points in estimation techniques?

  • Estimation Techniques-Function Points. A Function Point (FP) is a unit of measurement to express the amount of business functionality, an information system (as a product) provides to a user. FPs measure software size.

What is Function Point Analysis (FPA)?

  • Allan J. Albrecht initially developed function Point Analysis in 1979 at IBM and it has been further modified by the International Function Point Users Group (IFPUG). FPA is used to make estimate of the software project, including its testing in terms of functionality or function size of the software product.

Function points are one of the most widely used measures of software size. The basis of function points is that the “functionality ” of the system that is; what the system performs, is the measure of the system size.
