2) An organization's budget estimating process routinely misses the actual cost of a project by
25%. For the most recent project, the budget variance was a ridiculous 23%, but this must be
considered common cause variance.

3) In order to estimate completion of a Gaussian distributed activity with a 90% or higher degree
of confidence, the time may be overestimated by as much as 200%.

likely to begin project work right away.
