What is the purpose of tier groups in a domain network?

Tier groups in a domain network serve to create hierarchical tier definitions that represent different utilities. This hierarchical structure is essential for organizing the various components of a utility network in a logical manner. By categorizing utilities into tiers, it becomes easier to manage and analyze the network's infrastructure, allowing for clear differentiation between various levels of service or priority within the utility framework.

For example, in a water utility network, tier groups can help delineate primary and secondary distribution systems, facilitating better planning and decision-making processes. This structure can enhance clarity and efficiency in network management and operational planning, ensuring each level complies with specific operational standards and requirements.

Options related to physical layouts, user permissions, or maintenance schedules do not align with the primary functionality of tier groups. While these aspects are important in a utility network, they are addressed through other management tools and frameworks within the network's design and operational strategy. Thus, the focus on hierarchical tier definitions highlights the foundational role that tier groups play in organizing the utility network.
