When this estimate can be misleading

  • Results depend on the accuracy and consistent basis of user-entered assumptions.
  • The planner does not forecast demand, delivery performance or contract outcomes.
  • Use the result as educational business decision support, not accounting, tax or legal advice.
  • The proposal option profitability result uses only the entered commercial assumptions.
