In order to translate a message from SITH into a language more easily understood, C-3PO must risk losing his memory. C-3PO is able to back up his memory with R2-D2; however, this is very unreliable. C-3PO must conduct a Cost-Benefit Analysis, or determine the costs and benefits of any particular action to determine if the benefit received is greater than the cost of doing any particular action. Will the benefit of translating the SITH be worth the cost of potentially losing his memory? This is also a Trade-Off, since C-3PO must exchange his memory (at least temporarily) for the knowledge of what the SITH says. Learn more about Trade-Offs in this clip!
