Isolated work groups, also known as silos, are teams of people who work independently from other teams or departments. They are typically focused on a specific task or project and have limited interaction with other teams. This type of structure can be beneficial in certain situations, such as when a team needs to focus on a specific goal without distraction or interference from other teams. However, it can also lead to a lack of collaboration and communication between teams, which can lead to inefficiencies and missed opportunities.
