System development life cycle

When someone wants to make something big and complicated, like a new computer program or a building, they need to plan everything out before they start working on it. This is called the System Development Life Cycle.

First, they need to figure out what they want the thing to do, and who will use it. They will ask lots of questions and draw pictures to help them understand what they need to do.

Next, they will start making plans for how to make it. They will write down what the thing should do, and how it will look and work. They will also make a list of all the things they will need to build it.

Then, they will start building the thing. They will work really hard to make sure that it looks and works just like they planned.

After they finish building it, they will test it to make sure it works well. They will also ask other people to try it out and tell them if they find any problems.

Finally, they will make any changes that need to be made, and then they will release the thing to the world to be used by lots of people.

That's the System Development Life Cycle! It's a way to make sure that big things get built right, and they work the way they should.
