Murphy's laws of projects

• Vital papers will demonstrate their vitality by spontaneously moving from where you left them to where you can't find them.

• Adding manpower to a late project makes it later.

• Gordon's First Law: If a project is not worth doing at all, it's not worth doing well.

• Pournelle's Law of Costs and Schedules: Everything costs more and takes longer.

• The Ninety-Ninety Rule of Project Schedules: The first 90 % of the task takes 90 % of the time, and the last 10 % takes the other 90 %
