Include implementation early only when feasibility is central to the client's decision.

A standard implementation bucket can become filler if the case is primarily about diagnosing a problem or choosing among options.

For a market-entry case with major regulatory constraints, feasibility may belong in the initial structure. For a simple profitability diagnosis, it may not.

Ask what could change the decision now, and save downstream execution detail for later if it is not decision-critical.

If someone offers a referral immediately, I would still give them enough context to know what they are endorsing.

This is where live mocks helped more than solo prep for me because you get used to the awkward moment itself.
