The budget hotel example illustrates the application of Taguchi methods, which are named after Genichi Taguchi, who advocated “robust design” of products to ensure their proper functioning under adverse conditions.The idea is that for a customer, proof of a product’s quality is in its performance when abused.For example, a telephone is designed to be far more durable than necessary because more than once it will be pulled off a desk and dropped on the floor. In our budget hotel example, the building is constructed of concrete blocks and furnished with durable furniture.

Taguchi also applied the concept of robustness to the manufacturing process.For example, the recipe of caramel candy was reformulated to make plasticity, or chewiness, less sensitive to the cooking temperature. Similarly, our budget hotel uses an online computer to notify the cleaning staff automatically when a room has been vacated. Keeping the maid posted on which rooms are available for cleaning allows this task to be spread throughout the day, thus avoiding a rush in the late afternoon that could result in quality degradation.

Taguchi believed that product quality was achieved by consistenty meeting design specifications. He measured the cost of poor quality by the square of the deviation from the target. Once again, note the attention to standard operating procedures (SOPs) used by the budget hotel to promote uniform treatment of guests and consistent preparation of the rooms.
