Secrets to Variability Reduction

"Analysis and Control of Variation" is dedicated to revealing weaknesses in existing approaches to understanding, reducing, and controlling variation. Alternative approaches are recommended that are not only based on sound science, but also demonstra- bly work. The objective of the column is to combine sound science with proven practical advice. Reader comments, questions, and suggestions will help us fulfill our objective for this column. Please send your comments and suggestions to column coor- dinator John McConnell at john@wysowl.com.au or journal managing editor Susan Haigney at shaigney@ advanstar.com.
