Environmental scanning is when people look around at everything happening in their environment (which means the world around them) to find out what's going on. It's like looking at the world through binoculars to see what's happening far away from where you are.
People use environmental scanning to see what changes might be coming in the future, what opportunities there might be to do something new, and what things they need to be careful about.
So, imagine you're playing outside and you see a big cloud in the sky. You might scan the environment (look around) to see if there are any other clouds or if it's getting really dark. That way, you can decide if you should go inside before it starts to rain.
When grown-ups do environmental scanning, they might look at things like the news, the economy, and what other businesses or organizations are doing. They try to figure out what might happen in the future and how they can be prepared for it.
Just like when you scan your environment before you play outside, scanning the environment can help grown-ups make smart decisions so they can be successful in what they do.
