• The root cause for poor quality control is lack
  of solid empirical data on the cost effectiveness
  of a good quality control program. More than 50
  years of empirical studies have proven that
  projects with effective quality control cost less
  and have shorter schedules than similar projects
  with poor quality control. However, a distressing
  number of PMs are not aware of the economics of
  quality control
