THE DESIGN FACTOR IS THE DIFFERENCE BETWEEN THE ULTIMATE FAILURE STRESS AND THE WORKING STRESS. THIS IS NOT CONSIDERED A FACTOR OF SAFETY BUT IS REQUIRED FOR A STRUCTURE TO WORK. THEN THE ENGINEER CAN ADD HIGHER FACTORS OF SAFETY IF HE WANTS TO.

The two senses of the term are completely different in that the first is a measure of the reliability of a particular design, while the second is a requirement imposed by law, standard, contract or custom. Careful engineers refer to the first sense as a factor of safety, or, to be explicit, a realized factor of safety, and the second sense as a design factor, but usage is inconsistent and confusing, so engineers need to be aware of both.

They both mean the same thing.
If your calculated maximum design stress is 15,000 psi and you want to allow for a safety or design factor of 4, then you would choose a material with an allowable stress of 60,000 psi. 4 x 15,000psi = 60,000psi.
