Hi there! Do you know what a factory is? It's a big building where people make things like toys, clothes, and cars. Now imagine that instead of making toys, clothes, or cars, the factory only makes things for other companies. That's what a Contract Manufacturing Organization (CMO) does!
Let's say that a company wants to make a medicine to help people feel better when they're sick. The company might not have the equipment or the people to make the medicine themselves, so they ask a Contract Manufacturing Organization to do it for them. The CMO has all the equipment, the workers, and the expertise to make the medicine. They can make it for the original company and even put the company's name on the packaging.
The original company saves a lot of time and money by not having to build a factory and hire workers just to make the medicine. Instead, they pay the CMO to do it for them- kind of like they're "renting" the factory and expertise. It's a win-win situation for both companies.
In the end, the CMO gets paid for their work, while the original company gets the medicine they need to help people. So, that's what a Contract Manufacturing Organization is! It's like a factory that makes things for other companies.
