Under the objective Apply task decomposition techniques to structure complex requests, multi-domain deliverables requiring distinct data inputs demand modular, step-by-step composition.

Option A exemplifies best-practice task decomposition: first, establishing the overarching narrative and reporting goals; second, gathering and isolating domain-specific source material; third, executing dedicated, highly focused prompts to draft each detailed section (finance, operations, customer outcomes); and finally, feeding the finalized section drafts into Claude to synthesize a comprehensive, cohesive executive summary. In contrast, drafting the executive summary before the underlying sections exist (Option B) forces the model to invent conclusions. Dumping all disparate documents into a single monolithic prompt (Option D) risks attention dilution and superficial analysis. Merely concatenating isolated outputs without an overarching executive synthesis (Option C) produces a disjointed final deliverable.
