The term complexity stands for state of events or things, which have multiple interconnected links and highly complicated structures. In software programming, as the design of software is realized, the number of elements and their interconnections gradually emerge to be huge, which becomes too difficult to understand at once.

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.
The function point count at the end of requirements and/or designs can be compared to function points actually delivered. If the project has grown, there has been scope creep. The amount of growth is an indication of how well requirements were gathered by and/or communicated to the project team. If the amount of growth of projects declines over time it is a natural assumption that

The Function Point Analysis technique is used to assess the functionality delivered by software and a ‘function point’ is the unit of measurement. Identification of Functional Components The technique of functional modelling (functional analysis/ functional decomposition) is used to model the relationship between the transactions and the application as a whole.
The differences in function point size leads to very different kinds of development practices and to very different productivity rates at the low end compared to the high end. For example for some large systems finding and fixing bugs and creating paper documents cost more than the code itself.
7/01/2016 · Overview “Function Point Analysis” is probably as close to a pure engineering paradigm as one could get.
