Design methodology: which method explicitly uses the results of a design analysis as the basis for making the next round of redesign decisions?

Introduction / Context:
Modern product and software development embrace learning cycles. Rather than attempting a perfect design in one pass, teams analyze results (tests, simulations, user feedback), then redesign to address gaps. This loop continues until requirements and performance criteria are met. The approach is known as iterative design.

Given Data / Assumptions:

• Design analysis yields measurable outcomes (metrics, defects, usability findings).
• Subsequent decisions should be evidence-based.
• The method in question emphasizes cycles of analyze → redesign → validate.

Concept / Approach:
Iterative design leverages successive refinement. Each iteration sets hypotheses, runs evaluations (analytical models, prototypes, tests), and uses findings to guide the next design changes. This reduces risk by exposing problems early, aligns designs with user needs, and supports incremental investment.

Step-by-Step Solution:
Identify which method is defined by feedback-driven cycles.Recognize that “direct” and “design selection” do not inherently require iterative loops.Select “The iterative design method.”

Verification / Alternative check:
Frameworks like agile and spiral models formalize iterative learning: each sprint or cycle ends with review/retrospective and feeds the next iteration. This matches the described behavior.

Why Other Options Are Wrong:
“Direct method” implies a single-pass or straightforward application. “Design selection method” focuses on choosing among alternatives, not necessarily iterating on analysis feedback. “All” cannot be correct if some items do not guarantee iteration.

Common Pitfalls:
Skipping validation between iterations; making large scope changes without measuring impact undermines the iterative discipline.

Final Answer:
The iterative design method
