Hello !
I have carefully read the definitions for both types of contracts in the PMBOK Guide, in the PrepCast, and even in a prep book, but the difference still baffles me.
I understand that both concepts are very similar, you pay your vendor as you go based on the time the vendor spent and the resources the vendor used.
Could you please help me clarify what is the differentiator? It's not always straightforward to choose between the 2 in exam questions !
Thanks a lot
Romain
