The discipline of project management adheres to the dominant model of the project life cycle, or the phased stage-gate approach, of executing projects. This implies a clear definition of mission and system at the outset (to reduce uncertainty), and subsequent execution in phases with decision gates. This approach contrasts with the ways the seminal projects were conducted that are credited with establishing the foundation of the discipline in the 1950s. These projects started with missions that were beyond the currently possible, thus any solutions had to emerge over time. .
