I temped at a small MSC for a summer, and yes there is a lot of data analyzed and reported to the clients. In addition to the shop reports, there are frequent corporate recurring data reports with trends, statistics etc. that are provided regularly in big presentation binders. It seems some MSC use a standard report form, while many corps engage in specific, timely and detailed regional shopper reports. It was a small company, but it was interesting seeing that side of the industry.
