What should a Driver Engineer do before implementing a new pump chart?

A Driver Engineer should understand the specifics of the previous pump chart before implementing a new one because this knowledge is essential for effectively comparing the old and new charts. The previous chart provides critical information about the pump's performance, including flow rates, pressure settings, and required configurations under various conditions. By fully comprehending the previous chart, a Driver Engineer ensures that they can accurately assess any changes and make informed decisions based on how the new chart may differ in performance or operations. This understanding helps in anticipating any operational implications or adjustments that may be needed when transitioning to the new chart.
