Primavera P6

Primavera P6 (commonly just P6) is Oracle's enterprise-grade project scheduling and portfolio management tool. It is the de facto standard on UK major infrastructure programmes — Network Rail and HS2 supply chain contracts typically mandate it, as do National Highways programmes, large defence contracts and most multi-party NEC4 programmes above a certain size. It handles multi-project, multi-user working with resource levelling, EVMS reporting, schedule risk analysis integration and integration with Primavera Risk Analysis / Safran Risk for Monte Carlo analysis.

P6's dominance on UK major programmes reflects both its capability and its ecosystem: planners with P6 experience are widely available, third-party tools (Acumen Fuse, Schedule Analyzer, Deltek Acumen Risk) integrate with P6 databases, and contractual reporting templates in rail, highways and defence are designed around P6 data structures. The main alternative — Microsoft Project — does not scale to the multi-project, enterprise-database environment that P6 is built for, and is typically confined to smaller single-contract projects.

For organisations that must work in P6 because of a contractual requirement or client standard, the main risks are shallow expertise (treating P6 as a drawing tool rather than a network planning tool), database hygiene (multiple uncontrolled copies of the same project drifting apart), and user-role management (too many people with edit rights, no discipline around baselining). SOMA delivers Primavera P6 scheduling on live UK infrastructure programmes and runs Primavera P6 training for planners transitioning onto contracts where the tool is required.
