Reduce Cost

I still remember my “Managerial Accounting” lecture about how to reduce the cost of product.

He said “you must reduce every fixed cost to lowest as possible and let all be the variable cost, except in the time that you are already sure everything is fine: but believe me, if you careful enough that time never come.”

He also said that “you can reduce any cost but for the loyalty, don’t try to reduce that; it too hard to bring back loyalty when it down.”

So now I see what he meant.
