Human error generates great expense in the restaurant industry. A recent report from FoodDocs indicates that on average, human error costs the service industry around $30 per order. One widespread mistake is incorrect order taking, which can trigger anything from a negative review to a severe allergy. It’s also preventable if you reinforce some manual and tech-driven checks. Advise staff to confirm verbal orders when they are placed (and also when they are served). If you’re using a tech-based system to take orders, make sure the final screen lists the items clearly, along with any substitutions.
