what is the iron triangle in project management
Project management triangle The Project Management Triangle (called also the Triple Constraint, Iron Triangle and "Project Triangle") is a model of the constraints of project management. While its origins are unclear, it has been used since at least the 1950s.[1] It contends that:
Iron Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is by mass the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars, where it is the last element to be produced with release of energy before the violent collapse of a supernova, which scatters the iron into space.
