Primavera P6 and MS Project remain the two most widely used project planning tools, but they don't serve exactly the same needs. The choice shouldn't come down to habit, but to the actual complexity of the project being managed.
Primavera P6: built for complex programmes
P6 excels on multi-package projects with a high number of interdependent tasks — typically EPC projects, large infrastructure sites, or industrial programmes. Its detailed resource and cost management, plus what-if scenario simulation, make it the reference tool for dedicated planning teams and demanding contractual requirements (milestones, delay penalties, delay analysis).
MS Project: agility and integration
MS Project remains relevant for mid-sized projects, particularly when the organisation is already heavily invested in the Microsoft ecosystem. Its shorter learning curve and integration with Teams and Project Online make it an efficient choice for project teams without a full-time dedicated planner.
Planisware: the portfolio view
For organisations running several projects at once and needing to arbitrate between them — resource allocation, prioritisation, a consolidated view for leadership — Planisware adds a portfolio management layer that neither P6 nor MS Project natively cover.
The criterion that should decide it
The right tool depends less on team preference than on three factors: the project's contractual complexity (reporting requirements, penalties, potential claims), the size of the planning team, and the level of integration needed with your other systems. An experienced senior planner will guide you quickly — and, if needed, migrate an existing schedule from one tool to another without losing critical data.
