Software sizing

Software sizing is like building with Legos. Just like how you need a certain amount of Legos to build a specific structure, software sizing is a way of figuring out how much code, or "blocks," need to be written to create a program.

When someone wants to make a new piece of software, they have to figure out how much work will be needed to create it. They do this by breaking down the entire program into smaller parts, like building blocks. Each block represents a small piece of the program that needs to be written.

Then, they estimate how big each block will be. This is like estimating how many Legos you'll need for each part of your structure. They use different methods to do this, like counting lines of code, or estimating how complex each feature will be.

Once they've estimated the size of each block, they can add them all up to get the total size of the program. This is like adding up how many Legos you'll need for each part of your structure. The total size of the program gives them an idea of how long it will take to create the software, how many people will need to work on it, and how much it will cost.

So, just like how you need a certain amount of Lego blocks to build a specific structure, software sizing helps estimate how much code is needed to build a specific program.
