Picture a big circle. This circle is a group of people who all work together on something. In this group, there is one person who is the leader, and they are called the "node".
The node is in charge of making important decisions, and they tell the other people what to do. But, the other people are also important because they have their own jobs to do.
In a nodal organizational structure, the group is organized around the node. Everyone in the group has a specific role that they are responsible for, and they work together to get things done.
Think of it like a school playground. The node is the teacher, and they tell the other kids where to go and what to do. The other kids have their own jobs too: one kid might be in charge of organizing games, another might be in charge of making sure everyone is following the rules.
So, in a nodal organizational structure, everyone has a specific job and works together to achieve a goal. The node is the leader who guides everyone else, and everyone else has an important role to play in making things happen.
