What is the first step an administrator should take to create a new category for an organization?

The first step an administrator should take to create a new category for an organization is to choose a category set and then add a category. This process is essential because category sets serve as the overarching framework within which specific categories can be defined. By first identifying the appropriate category set, the administrator ensures that the new category aligns with the existing organizational structure and helps maintain consistency in data organization. Once a category set is selected, the administrator can then proceed to add a specific category that fits within that framework, thereby facilitating better data management and discovery for users within the ArcGIS Online environment.

The focus on category sets emphasizes the hierarchical nature of categorization in ArcGIS Online, which enhances the usability and effectiveness of the categorization system overall. Other steps mentioned, such as selecting groups or items, pertain to applying existing categories rather than creating new ones, which clarifies why adding the category after choosing a category set is the logical first step in establishing new organizational structures.
