involved in is meaningless. if 10 people at a table all offer their inputs, it doesn't matter if mine is the rational one, or even if I hedged against their irrationality with an inflated estimate, the 9 other estimates will dominate. That's the whole problem here, a lack of autonomy and a lack of expectations for responsibility. Make the developer responsible for the estimate, and hold them accountable for the results. Letting the organization make the estimate and then blaming an LLM for the failure is a recipe for company collapse.
