Which term fits best for repeatedly improving by testing and tweaking?

• A. Clarify
• B. Encourage
• C. Fail-Forward
• D. Iterate

Answer: (D)

Repeated improvement through testing and tweaking is an iterative process. Iterate means to go through a cycle again and again, with the goal of refining the result each time. In practice, you try something, observe how it performs, make adjustments, and try again, steadily building a better outcome with each pass.

Clarify focuses on making something clear or understandable, not on a cycle of testing and refining. Encourage is about giving support or motivation. Fail-Forward emphasizes learning from mistakes as you move ahead, which is related to improvement but doesn’t specifically capture the ongoing cycle of testing and tweaking that “iterate” conveys.
