It's easy on small teams on small products. Eventually, as capitalism demands eternal growth, they grow to the point that the complexities and hack jobs that were used to deliver previous estimates impact them. Then no one wants to turn up with a realistic estimate. Eventually all the estimates become lies because of the incalculable complexity of the estimation process that results from the complexity of the product and your options are usually to try and lie and deliver late, but not later than other teams in the org.

Every org I've worked for ends up like this.

There is a lot or intellectual dishonesty out there. It used to bother me. It doesn't now. I just don't partake in it.
