Title:

Monitoring & Improving Quality via Consumer Complaints - A Statistical Engineering Case Study

 

Abstract:

Procter & Gamble (P&G) receives millions of consumer comments each year and requires an efficient data-mining algorithm to identify products with unexpectedly high complaint counts, as these suggest potential quality or safety issues (aka “signals”). This talk will present an overview of P&G’s adopted signal detection method, the Multi-Item Gamma Poisson Shrinker (MGPS), an empirical Bayesian method for disproportionality analysis. It will also discuss the application of text mining on consumer comments to find misclassified adverse events and identify fraudulent complaints.  I will finish the talk by relating certain aspects of this case study to the statistical engineering framework proposed by Roger Hoerl and Ron Snee in their 2017 American Statistician paper, “Statistical Engineering: An Idea Whose Time Has Come?”
