  • Question 4

    The cockpit of an airplane is a more complex example of a collection of instruments that reports information critical to
    successful air travel. The driver of a car or the pilot of an airplane monitors multiple indicators of performance
    simultaneously to arrive at the intended destination successfully. At any given point in the journey, the driver or pilot

    the indicators. This example depicts that dashboard tools that report on the ongoing performance of the critical
    processes that lead to:
  • Question 5
