A project manager needs a detailed six-month plan for an office relocation. Her first attempt, a single prompt asking for 'a complete relocation plan,' produced a long but generic document. What is the most effective way to proceed?

Answer: D — Give Claude the real constraints, then build the plan in stages: phases first, then one phase at a time, then a critique.

Staged planning with real constraints (budget, dates, team, dependencies) lets her correct direction early and produces a plan specific to her situation, and a critique step finds weak spots (d). 'More detail' (a) or a bigger model (b) doesn't supply the missing constraints. Accepting a generic plan (c) gives up most of Claude's value.
