In mathematics, and more specifically in naive set theory, the domain of definition (or simply the domain) of a function is the set of input or argument values for which the function is defined. That is, the function provides an output or value for each member of the domain.iven a function f: X â Y, the set X is the domain of f; the set Y is the codomain of f. In the expression f (x), x is the argument and f (x) is the value. One can think of an argument as an input to the function, and the value as the output.
The PMI provides services including the development of standards, research, education, publication, networking-opportunities in local chapters, hosting conferences and training seminars, and providing accreditation in project management.
One of the key tasks of the PMO is to manage the project management system of an organization and supplies all project teams with PM policies and guidelines. Part of a PMOâs job is also to offer training to project team members (see 6.) or implementing an enterprise-wide project management software. This enables the PMO to ensure that every department and project team in the organization uses the same methods and tools.
