Function Points measure systems from a functional perspective and are independent of technology. Hence, regardless of technology, language, development method, or hardware/software used, the number of function points for a system will remain constant. The variable in Function Point Analysis is the amount of effort required to deliver a given set of function points. Ratnabhumi offers function point analysis services so that the customer is benefited in the following areas:

	Function point analysis can be used to determine which environment/language/tool is more productive.
	Function point analysis can provide a mechanism to track and monitor scope creep.
	Function point counts at the end of each phase/stage of a project can be compared to the function points actually delivered.
	If the number of function points has increased then there has been a scope creep.
	The number of function points that has increased or decreased defines the project growth.
	If the project has grown then it is a sure indication that the requirements haven’t been gathered well and there has been some scope creep.
	If the project growth has declined then the communication between the end-user and the development team has improved.

Process of Counting Function Points:

	Identification of the subsystem boundaries
	Identification of the data functions (internal logical files and external interface files)
	Identification of transactional functions (external inputs, external outputs and external inquiries)
	Calculation of the Unadjusted Function Point (UAF) Count
	Determination of the Value Adjustment Factor (VAF) using General System Characteristics (GSC)
	Calculation of the final Function Point Count
