Heyland–Ossanna circle diagram

Imagine a big piece of paper that has a circle drawn on it. This circle is divided into different sections like slices of pizza. Each section represents a different group of people or things. Now, let's talk about the Heyland-Ossanna Circle diagram, which helps us understand how these different groups relate to each other.

In the middle of the circle, there is a group called the "Core Team." This is like the main group of people who are responsible for creating and managing something, like a project or a business. They are the ones who make the important decisions and guide the overall process.

Now, imagine that there are other groups that are connected to the Core Team through lines or arrows. These groups are called "Extending Team," "Contributors," and "Users."

The Extending Team is like a group of helpers. They support the Core Team by providing additional skills or resources that are needed to make things work smoothly. They might be experts in a specific area that the Core Team may not have much knowledge about.

Contributors are like people who give their ideas, opinions, or help in some way. They might not be part of the main Core Team but contribute to the project or business in different ways. They can offer suggestions, feedback, or even help with small tasks.

Lastly, Users are the people who benefit from the project or business. They are the ones who use the final product or service that the Core Team and others have been working on. For example, if we are talking about a video game, the Users are the people who play the game and have fun with it.

Now, let's go back to the circle. The lines or arrows connecting these groups show us how they interact with each other. They can represent communication, feedback, or even exchange of resources. These connections are important because they help everyone work together towards a common goal.

By using the Heyland-Ossanna Circle diagram, we can see how all these different groups are connected and how they contribute to the overall success of a project or business. It helps us understand that teamwork and collaboration are key to making things work effectively. So, it's like a map that shows us the different players in the game and how they can work together to achieve something great.
