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.
In other words, Project control is essentially equivalent to the project management process stripped of its facilitating sub-processes for safety, quality, organizational, behavioral, and communications management. Importance of Project Controls : The successful performance of a project depends on appropriate planning. The PMBOK Guide defines the use of 21 processes that relate to planning out of the 39 processes for project management, (Globerson & Zwikeal 2002). The execution of a project is based on a robust project plan and can only be achieved through an effective schedule control methodology. The development of a suitable Project Control system is an important part of the project management effort (Shtub, Bard & Globerson 2005).
