Alan Mark Davis, Nurie Nurmuliani, Sooyong Park, Didar Zowghi · 2008
Numerous studies have shown that a software projectpsilas cost, schedule and defect density escalate as the rate of requirements change increases.

This paper explains why a project incurs just as much, if not more, risk when requirements changes are suppressed.
