Nothing ever gets built on schedule or within budget. All's well that ends. A meeting is an event at which the minutes are kept and the hours are lost. The first myth of management is that it exists. A failure will not appear until a unit has passed final inspection.
New systems generate new problems.
To err is human, but to really foul things up requires a computer. We don't know one millionth of one percent about anything. Any given program, when running, is obsolete. Any sufficiently advanced technology is indistinguishable from magic. A computer makes as many mistakes in two seconds as 20 men working 20 years make.
