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. All estimates have precision and accuracy. Deciding how much precision and accuracy is needed for a credible estimate is critical to the success of that decision.

If we look at the discipline of software engineering, we see that the microeconomics branch of economics deals more with the types of decisions we need to make as software engineers or managers. Software engineering economics." IEEE Transactions of Software Engineering, 1 (1984): 4-21.

This can be the confidence in the estimate for any variable. But is can be ANY variance for the program, including confidence in the estimates of future performance - cost, schedule, or technical performance. This usually results in a project's actual costs far outrunning the optimistic estimates and creating a large overrun.

Some feel that the cone does not provide any value for the work they do and does not match the reducing uncertainty in their estimates. First, the Cone of Uncertainty is a Principle used to define the needed reduction in the variances of estimates on Programs. Remember Risk Management is How Adults Manage Projects - Tim Lister.

40 - Estimation is a Problematic Practice of Companies Doing Dangerous Things. A #Noestimates advocate makes the claim that having a ±10% accuracy for estimates of cost and duration is a dangerous thing. Define the probabilistic ranges of the work in a single point estimate manner. 6, No 5, October 2014. [3]

In all engineering worlds, from software engineering to bending metal for money, there is really nothing new under the sun. Rarely are software engineers working on science experiments. maybe a read of the resources of Estimating Agile Software Development may help. Almost impossible?

So here are some books, handbooks, and guides that sit on my shelf that are used pretty much all the time on the Software Intensive System of Systems we work on. But when some statement is made about risk, estimating, performance modeling, or the like - always ask for references. I'm not expecting anyone to read all these books.
