One of my favorite restaurants is in the swankier part of town, surrounded by high-end designer shops and oddly overpriced candy stores. The restaurant serves French cuisine, has a happy hour worth ditching work early for, and the ambience of a California vineyard on a bright, sunny day. If guests aren’t dressing up to come here with their purse-size pooches, they dine in one of the many other “fancy” establishments. For such a prime location, it’s expected that service will be impeccable.

But it’s not. The staff is sometimes rude and you have to wait long periods of time before the waitstaff gets to you to take your order or bring it out to you. 

What this restaurant is missing is the fulfillment of what we know in the software testing industry as non-functional requirements.
