Answer:
Though the current system is efficient, is it perfect
Step-by-step explanation:
An idea grower is someone that is open to analyzing different ideas, possibilities, or options on how to improve the current production system. I'm not sure if anything can be considered to be perfect, since we all have flaws, and the things that we make all have flaws. The difference is that things or systems are those that have the least amount of flaws and work almost efficiently most of the time.
In this case, the production system might be very efficient, but it can always be improved. It is charlie's duty to try to find ways to continuously improve it.
