A man stopped at a countryside coffee shop and ordered a cup of coffee. A young waitress who was having a bad day grudgingly delivered it and asked: ‘Anything else?’ The customer smiled and said: ‘I’d like some sugar, cream, a spoon, a napkin and a saucer for the cup.’
‘Why didn’t you tell me earlier?’ snapped the waitress.
‘Look at it this way,’ said the customer. ‘You served a cup of coffee, made five mistakes. And here you are debating with me.’
If you are the owner of the coffee shop, how would you handle the situation? Scold the waitress and apologize to the customer or do nothing? After all, the man was obviously from out of town and is not expected to be a repeat customer.
To give you another perspective, operational mistakes can create opportunities for improvement. A case in point is Japan’s ‘restaurant of mistaken orders,’ a famous business initiative with a unique social mission. Its frontline waitresses are elderly individuals with dementia or cognitive impairment.
Customers know beforehand that the person taking their order might forget what they requested. They could bring the wrong food or sit down to chat with them as if they’re long-lost relatives. And that’s exactly the point.
Understanding the situation, customers would simply smile at the mistakes and accept whatever food that was brought to them. It doesn’t make any difference as every item on the menu is carefully prepared by professional chefs so that regardless of the error, customers would get a fantastic, high-quality meal.
Overall, the environment is intentionally warm, entertaining and lighthearted. Mistakes are not treated as service failures. Instead, they are embraced as light moments of social connection buoyed by warm acceptance and laughter.
Restaurant poka-yoke
If the coffee shop can’t create similar opportunities for their mistakes, then what would be the owner’s options? I told the owner to be attentive to trivial issues. A customer complaint is a gift. Discover how to improve the situation with the most common mistakes. Rank them according to its financial impact.
He gave me a list of top three processes with the highest number of errors committed by employees and their customers. The first one contributed to around $3,000 losses per year. It may not be a big amount for some people, but for a struggling shop owner, it means a lot.
I told the owner to consider poka-yoke, a Japanese approach toward error-proofing.
He was reluctant. For him, poka-yoke seemed an unusual solution. I explained that it is not an exclusive tool for manufacturers. We encounter it as an everyday solution like the following examples when using a computer:
‘Do you want to save your document?’ or ‘Are you sure you want to log-off?’ The same principle has it in microwave ovens. You can’t operate them while its door is open.
Examples
American psychologist Abraham Maslow (1908-1970) suggested that sinfulness in human behavior is not primary instincts, but reactions to frustrated basic human needs. Errors happen due to many factors like employee fatigue, loss of concentration, personal problems, poor work system and lack of understanding, among others.
To avoid mistakes, restaurants and coffee shops can explore the following techniques:
1. Use colored plates for allergen orders, vegetarian orders and standard orders.
2. Eliminate manual weighing by using fixed-volume portion scoops.
3. Group items by process and cooking time.
4. Implement color labels for inventory.
For other examples, refer to the above illustration.
So, how can you argue against poka-yoke? You can’t. Poka-yoke is low-cost, practical and easy to do. Unfortunately, some managers or their organizations continue to ignore it, mainly because they don’t understand it well enough.
The coffee shop story highlights how easily small service gaps can develop into serious operational failures. While traditional, heavy-handed inspections only delay service without solving the root cause, poka-yoke offers a low-cost, common-sense alternative.
In conclusion, stop treating customer complaints like inconvenient fires to extinguish. Treat them as signals of weaknesses in operational design. Poka-yoke is an uncompromising tool to prevent predictable human error from wrecking your bottom line.
Companies that embrace proactive mistake-proofing don’t just protect their employee morale and market share; they systematically render their competition obsolete.
