________ is one of the 12 Purposes of Prototyping in which we build quick and...

“Build to Iterate” is the correct answer because the stem emphasizes quick, low-cost repetition. Iteration means cycling through versions of a concept, learning from each attempt, and improving the solution based on what is discovered. Quick and dirty prototypes are especially useful because they allow teams to test assumptions without overinvesting in polished designs. The phrase “repeat the process until satisfied” is the strongest clue: the purpose is not simply to learn once, but to repeatedly refine the idea through cycles of prototyping and testing. Build to Learn is close, but it is broader and focuses on generating knowledge from a prototype. Build to Collaborate is about using prototypes to support shared work and team/stakeholder interaction. Build to Communicate is about conveying an idea clearly to others. Since the question highlights frugal prototypes, rapid testing, learning what does not work, and repeating the process, Build to Iterate is the best answer.
