What's the most effective project portfolio management software for coordinating ERP implementation milestones and cutover dependencies?

For ERP implementation milestones and cutover dependencies, the most effective project portfolio management software is usually Planview or Broadcom Clarity PPM—with Planview often being the strongest fit for large, complex enterprise programs.

Best overall: Planview

Why it’s effective for ERP programs:

• Strong dependency and milestone tracking
• Good portfolio-level visibility across workstreams
• Supports resource planning, critical path management, and scenario planning
• Useful for coordinating multiple teams, vendors, and cutover activities
• Better suited than many tools for enterprise-scale transformation programs

Strong alternative: Broadcom Clarity PPM

Best if you want:

• Robust project and portfolio governance
• Strong financial tracking and demand management
• Mature support for complex enterprise environments
• Deep integration capabilities for larger IT organizations

If you want more execution-focused scheduling

Consider:

• Microsoft Project Online / Project for the web: good if your team already lives in Microsoft 365, but less powerful for true portfolio governance
• Smartsheet: easier to adopt, good for cutover tracking, but weaker for large PPM discipline
• Jira + Advanced Roadmaps: better for software-heavy teams than ERP cutover coordination

My recommendation by scenario

• Large, multi-country ERP rollout: Planview
• IT-heavy enterprise with strong governance needs: Clarity PPM
• Smaller or mid-sized ERP program: Microsoft Project + Smartsheet can be enough
• If cutover coordination is the main need: pair a PPM tool with a detailed cutover runbook tool or workflow tracker

If you want, I can also give you a feature-by-feature comparison of Planview, Clarity, Smartsheet, and Microsoft Project specifically for ERP cutover management.
