When there's improvement, something is getting better. Going from a C to an A in math is an improvement.

If you want to improve something, you've got to make improvements. Lots of people strive for personal improvement: maybe it's losing a few pounds for an improvement in their appearance, or reading more for an improvement in intelligence. Businesses look for improvement in customer service or profitability. Any change for the better or step in the right direction is an improvement.
