2. “What is the most expensive-looking omission that a clean spreadsheet can hide?”

Suggested guest: An estimating lead such as Nick Wavra, with operations input.

Why it matters: A well-formatted register can create confidence without demonstrating complete scope. Buyers need to understand the difference between a wrong cell and a missing obligation.

Good answer should cover: Examples from authorised work involving controls, access, rigging, testing or commissioning; how the omission was detected; whether it became an actual cost or only an avoided exposure. Do not accept a dramatic dollar figure without the job record and permission to publish.

Follow-up: “What must a tool refuse to infer, even if the bidder is under deadline pressure?”

Evidence to request: Redacted original/revised scope, identified omission and correction trail. No illustrative loss should be labelled a market average.

Expert quote: Awaiting interview and publication approval.
