Sampling Supermarket Statistics
Abstract: What started as a straightforward statistical analysis for a large North American wholesale grocer became a true application of statistical engineering. The team at Straight Line Performance Solutions designed and delivered a solution for a corporate audit team that provided new ways of looking at how they measured and tracked customer quality, what standard practices they followed and how they staffed their auditing facilities to maximize their value. The application involved multiple statistical techniques and touched upon all levels inside and outside the organization; from warehouse auditors, to the C suite, to their customers.
