The goal of this exercise is to create a new standard category.
In practice, this will not be done very often because standard categories tend to be relatively stable. Also, if you are creating a method plug-in that extends an existing method, you should try to use the standard categories before creating new ones.
Standard categories provide a means to categorize core method content in line with best practices for creating structured methods. To encourage good method structure, there are standard categories for grouping tasks into disciplines, work products into domains, roles into role sets, and tool-mentors into tools. Unlike custom categories, standard categories, by definition, are linked to a specific type of method content.
Examples include role sets with roles, disciplines with tasks, and domains with work products.
