Under the objective Adjust approach based on feedback and results, iterative refinement requires tight, closed feedback loops characterized by concrete observation, targeted modification, and empirical evaluation.
Option A details the gold-standard iteration cycle: capturing specific, granular defects immediately following an execution run (e.g., tone misalignment, omitted edge cases, formatting errors), translating those observations into targeted, discrete adjustments in prompt instructions or workflow logic, and validating whether subsequent outputs resolve the issue without regressions. In contrast, deferring feedback collection across multiple unmonitored cycles (Option B) delays error detection. Relying solely on high-level aggregate numerical ratings (Option C) lacks the actionable diagnostic detail needed to locate root causes. Applying sweeping, unfocused prompt overhauls (Option D) obscures cause-and-effect relationships and frequently introduces new failure modes.
