Starbucks calls it “transactions per hour” but from our perspective, it’s waiting in line. Researchers say that it takes only 3 minutes in a queue for us to become impatient.
Hoping to show their shorter line time and higher sales, Starbucks used this slide at a 2013 investors meeting:
When I asked my barista Josh about Starbucks’s productivity, he suggested I look at LEAN. Originating with Toyota, the LEAN approach involves repeatable routines that minimize wasted movement.
When LEAN was first implemented at Starbucks, executives visited stores with stopwatches. They saw employees who were bending to scoop beans and blocking espresso machines when frothing milk. Observing 25 seconds per drive-in customer and 6 seconds for a drink to get its drizzle, they thought they could do better.
This recent video shows some of the results:
With I Love Lucy, the repeatable routine did not quite work.
In a monopolistically competitive market with many small coffee establishments that can enter and exit with relative ease, Starbucks needs more than popular products. The bottom line is also about labor productivity.
