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)?
