Function Point

Function Point is like counting how many parts you need to build a toy. Just like how we need different parts like wheels, body, arms, and legs to make a toy, Function Point measures how many different parts or components there are in a software program.

So, when someone wants to build a software program, they need to know how complex it will be and how many parts are needed to build it. Function Point helps to measure the complexity of the software program by identifying its different components.

For example, imagine you want to build a program like WhatsApp. The Function Point of such a program will include things like the number of buttons needed, the number of screens required, the number of input fields for messages, etc. All of these components add up to the total Function Point for the program.

This method of measuring Function Point helps software developers to plan and estimate the time, effort, and cost required to build the program. It also helps to track progress and provide accurate feedback on the project's completion.

In summary, Function Point is like counting the different parts or components required to build a software program, just like counting the parts needed to make a toy. It helps software developers to measure the complexity of the program and estimate the time, effort, and cost required to build it.
