In this specific system orders come in in bulk between 08:00 and 18:00, but the other 14 hours in a day and during the weekends the machine is mostly idling. We could tune this system for power efficiency, so as not to waste to much energy during the 118 hours a week it is doing almost nothing, or we could tune it for peak performance during the 50 hours a week the system is heavily utilized.

A professional takes a course or works toward a certification because they want to build their skills and advance their career, or they bring in consultants to optimize the technologies and processes they use.
Improvement increases the chances of success.
