Which design approach explicitly uses analysis feedback to iteratively refine and effect the design until requirements are satisfied?

Introduction / Context:
Design rarely proceeds perfectly from first attempt to final solution. Iterative methods deliberately alternate between analysis, synthesis, and evaluation, using feedback from tests, prototypes, or simulations to converge on a design that meets constraints and performance targets.

Given Data / Assumptions:

• Requirements may be evolving or partially uncertain.
• Prototypes and analyses produce measurable feedback.
• The process repeats until acceptance criteria are met.

Concept / Approach:
Iterative design embodies the loop: analyze → design → evaluate → refine. Each cycle improves fidelity and correctness. This is distinct from “direct” (one-pass) or “selection” (choose among existing alternatives without substantive redesign) approaches. Iteration leverages analysis explicitly to effect design changes.

Step-by-Step Solution:
1) Identify the approach that fundamentally depends on repeated analysis for improvement. 2) Recognize that “iterative design” names this loop explicitly. 3) Exclude “direct” as single-pass and “selection” as choice among options without iterative refinement. 4) Select the iterative design method.

Verification / Alternative check:
Engineering lifecycles (spiral, agile) and UX processes rely on iteration to reduce risk and incorporate feedback, confirming the concept.

Why Other Options Are Wrong:
Option B: Direct methods minimize or omit iterative feedback loops.
Option C: Selection focuses on choosing among candidates rather than shaping a design through repeated analysis.
Option D: Cannot be correct because B and C are not iterative by nature.

Common Pitfalls:
Stopping iteration too early and locking in suboptimal choices; ensure each loop tests against clear, quantified acceptance criteria.

Final Answer:
The iterative design method
