Analyzing how to distribute tasks between our human operators and any technology/automation by evaluating the basic functions that must be performed tends to happen in what type of analysis? 

Why is a holistic perspective (systems thinking) important to human-centered design? 

We are going to test driver performance with and without cell phone use. However, we also want to evaluate if driving in the day or the night impacts performance while using a cell phone. What type of experimental design is best for this setting? 

Which of the following are ethical considerations we must adhere to when designing and conducting an experiment?

The kitchen brigade is a _______ style chain of command.

A factory assembly line is being designed. The location is a large open warehouse that does not contain any air conditioning or heating functionality due to its old age. Additionally, the high ceilings prevent the effectiveness of using any ceiling fans. However, workers must wear long pants and long sleeves, large gloves, ear protection, and eye protection while working. What is a safety issue that stands out in this scenario?
