What happens if you shift focus from "accurate estimation" to "reliably shipping by a date"? . If your project has no uncertainty, there is no need to estimate. The naturally occurring work effort in the development of a software feature - even if we've built the feature before - is an irreducible uncertainty.

It is popular to claim we've never done this before, so how can we possibly estimate the cost and schedule. If it truly hasn't been done before, then the software project is likely to be an inventing new physics project. In that world, we still made estimates of the cost to design, build, and operate the experiment.

Because of the limitations of resources, projects need to operate withing a world of limited resources, the uncertainties - both reducible and irreducible - that create risk, and the emerging attributes of all project work. This is the foundation for estimates. These estimates are critical to both developers and customers.
