Everywhere at Once: Chef Geoff Tracy’s Data-Driven Empire. Geoff Tracy and his brother use a set of 800 stan­dards to mea­sure the per­for­mance of their restau­rants. A cou­ple examples:

Did Elizabeth bring your Pinot Gris within three min­utes of the time you ordered it? Were your appe­tiz­ers deliv­ered within seven min­utes, entrées within ten, desserts within seven? Were these plates described at the table before they were set in front of you? Were nap­kins refolded when you went to the restroom? Was non-bottled water referred to as “ice water” (cor­rect) or “water” (incorrect)?
