There are different types of internal communities. The first is the practice community where the members belong to the same core business, share their knowledge, and help each other. The community of action brings together people with a common objective or project to improve a product, process, or their company in general. The interest community unites employees wanting to share and exchange their passion and interests with other employees, without any link to work. Finally, the community of place brings together people who work in the same place, city, or country.
