Forty blocking questions sit across this business case. Almost none can be answered at a desk — they need seven conversations. This page is one brief per counterparty: who to call, what to ask in what order, what a good answer sounds like, what a bad one means, and what each call releases. Print it and take it to the phone.
One rule for all of them: ask what it costs and what it takes. Price is usually the easy half — capacity, lead time and whether they will deal with a first-time customer at all are what actually decide the plan.
Compiled August 2026 from the open questions on every page of this business case. The questions are framed to get usable answers rather than polite ones; adapt the tone, not the content. Nothing here is legal, tax or financial advice — several of these calls exist precisely because this business case cannot answer the question and a qualified party must.
