Question

Which of the following is NOT an example of robust process design?

• A fire alarm that goes off when a fire is detected in a building 
• A saw that will not start if the blade is not inserted properly in its housing 
• A building that can withstand a major earthquake 
• A colorful liquid laundry packet that resembles a piece of candy

Answer 1

Answer: A colorful liquid laundry packet that resembles a piece of candy

Explanation:

A robust process design is defined as the one that can tolerate the variations in input without increasing variation to the output. A colorful liquid laundry packet that resembles a piece of candy is not an example of robust process design as this design does not help to withstand the variations in input to the washing process. From the given options, a saw that will not start if the blade is not inserted properly in its housing is an example of robust process design using fool proofing by eliminating the opportunity for mistake. A building that can withstand major earth quake is a robust process design using overengineering and a fire alarm that goes off when a fire is detected in the building is an example of robust process design using early warning.
