I'm not going back over the years of being lead to believe we are close to the finish line only to be told "more work" had to be done and estimated costs to finish drastically went up. It's happened so many times over the years it's laughable that you are even trying to defend it.
You must not work on the corporate/financial/management side of business. I've yet work at a company where budgets are treated as loosely as you're trying to convince me they should be treated. Why bother publicly putting out estimates if there's no reliability or credibility in them? That goes against so many financial and auditing principles it's ridiculous. People use those figures to make financial decisions. If they're useless then why disclose them?
