Glenday Sieve (GS) - definition(s)

Glenday Sieve (GS) - An analysis technique that allows practitioners to prioritize and target improvement efforts on a few high-volume procedures, processes, units or activities (PPUAs). As seen in the table below, GS maintains that in most cases about 6 percent of PPUAs account for about 50 percent of volume. Additionally, GS classifies and color-codes all PPUAs into four different volume groups. For example, if a manufacturer makes 200 different parts, GS maintains that approximately 12 parts account for 50 percent of sales; these 12 parts would be in the green group and would ideally be the focus of any initial improvement activities, as they would yield the greatest benefit.

   Cumulative Percent of Volume     Cumulative Percent of PPUAs      Color Code
   50 percent                       6 percent                        Green
   95 percent                       50 percent                       Yellow
   99 percent                       70 percent                       Blue
