P3 allowed for the assignment of labor, material, and equipment resources to activities.
During the 1990s, P3 achieved a market share dominance in the construction and engineering industries that approached monopoly status. Government agencies (such as the US Army Corps of Engineers) and major contractors mandated the use of P3 for all tender submissions. This ubiquity created a standardized language of project management (Activity IDs, WBS codes, and float analysis) that persists today. primavera p3 software
