What-if simulations for project forecasting

Test different project scenarios to see how new work, scope changes, and staffing shifts affect timelines, workloads, and budgets across your portfolio. Model scenarios in seconds so you can say yes, not yet, or not now with clear evidence.
Scenario modeling

Run what-if scenarios before you commit.

  • Model scenarios across projects, programs, portfolios, and initiatives in one place.
  • Test if you can add a new customer or project and still meet existing delivery dates.
  • Evaluate how scope changes and shifting priorities affect work already in progress.
  • Compare scenario outcomes to support intake, planning, and annual roadmap decisions.
  • Use consistent what-if modeling instead of rebuilding schedules in spreadsheets.
AI scenario modeling across projects and portfolios
Forecasting and resource impact simulations
Predict impacts

See how every change affects delivery, budgets, and capacity.

  • Simulate PTO, reassignments, or loss of key resources to see real capacity impacts.
  • Test adding new projects or customers and visualize which milestones move.
  • Recalculate budgets and workloads instantly for each proposed scenario.
  • Identify which initiatives or timelines carry the highest delivery risk.
  • Present visual scenario summaries that clarify trade-offs for executives and PMOs.
  • Document the options considered and decisions made for future reference.
DIFFERENTIATORS

What sets Project Insight's what-if simulations apart?

Capacity views can show you where people are overloaded. Project Insight goes further by letting you test what to do about it before you change the live plan. Model a new project, a shift in priorities, a delayed start date, PTO, or a reassignment using current project, resource, and budget data. Then see how that choice changes schedules, workloads, capacity, and costs across the portfolio.

Smartsheet and Jira also offer saved what-if scenarios. Project Insight stands out by bringing portfolio-wide capacity and budget impact together with AI-informed resource and schedule suggestions, so leaders can compare practical options and apply the one they approve without rebuilding the plan.

Model real planning decisions Yes: Test new work, scope and priority changes, schedule shifts, PTO, and reassignments Yes: Adjust project timelines, resources, and allocations Related capability: Adjust tasks, estimates, assignments, and capacity in planning views Related capability: Adjust effort, timelines, resources, and allocations in planning views Related capability: Adjust project allocations and team capacity in planning views Related capability: Schedule and reassign work through workload and resource views Yes: Test alternate versions of a plan, including schedule and team-capacity changes
See the impact across projects and resources Yes: See the effect by person, role, department, project, program, and portfolio Yes: Timeline and capacity views show project and cross-project allocation impact Related capability: Workload views show capacity across selected work Yes: Capacity Manager brings together allocations across projects and portfolios Yes: Workload and Capacity Planning show team demand across projects Yes: Workload Charts and Resources view show effort across teams and projects Related capability: Plans can span multiple teams and work sources; capacity is team-based
See budget impact inside the simulation Yes: Simulated changes can be reviewed in Budget Portfolio reports, including labor and non-labor data when configured Not documented in scenario workflow: Scenario Planning documentation focuses on timelines and capacity Not documented in scenario workflow: Cost fields and reporting are separate from workload planning Not documented in scenario workflow: Cost management is separate from capacity planning Not documented in scenario workflow: Cost data can appear in capacity views with the Timesheets and Budgets add-on Not documented in scenario workflow: Budgeting and workload planning are available as separate capabilities Not documented: Jira Plans documentation does not include project-budget simulation
Get AI-informed options inside the simulation Yes: AI can suggest resource moves and schedule options using availability, roles, and current workload Not documented: AI recommendations are not described in Scenario Planning documentation Not documented: No comparable AI-assisted simulation workflow is described Not documented: No comparable AI-assisted simulation workflow is described Not documented: No comparable AI-assisted simulation workflow is described Not documented: No comparable AI-assisted simulation workflow is described Not documented: Scenarios are documented as a planning tool, not an AI-assisted workflow
Compare the original plan with proposed changes Yes: Show prior totals, simulated totals, and the change in resource-allocation reports Yes: Compare scenarios in timeline and capacity views Related capability: Compare workload and capacity views after changing planning data Related capability: Review allocation and capacity data across connected projects Related capability: Review planned allocations and team capacity Related capability: Review effort and capacity in workload and resource views Yes: Switch between scenarios and review proposed changes before saving
Apply the approved option to live work Yes: Apply the selected dates and assignments to the original project plan Yes: Apply the selected scenario to the plan of record Different workflow: Planning changes are made directly to the underlying work Different workflow: Planning changes are made directly in resource and capacity tools Different workflow: Allocation changes are made directly in planning views Different workflow: Schedule and assignment changes update the planned work Yes: Save selected scenario changes back to Jira work items
