Integrated Analysis

Open Tool

Use For

  • Cost-loaded schedules
  • Time-dependent cost analysis
  • Cash flow projections
  • Cost-schedule correlation
  • What-if scenarios
  • Full project risk picture

Inputs

  • Schedule (tasks, durations, predecessors)
  • Cost items linked to tasks
  • Cost type (Fixed/Variable)
  • Schedule risks
  • Cost risks

Outputs

  • Schedule P-values (dates)
  • Cost P-values ($)
  • Cost-schedule scatter plot
  • Monthly burn-down (P50/P90)
  • Cumulative cost curve
  • Dual sensitivity analysis
  • Excel report (7 sheets)
Variable Costs: Costs marked "Variable" scale proportionally when linked task duration changes. Fixed costs remain constant.
