4 4 / Why Human Factors? Set switch B47 to on Switch B47 No! You set switch B47 to on Taken from

5 5 / What is Human Factors? The study of how humans behave physically and psychologically in relation to particular environments, products, or services. User-Centered Design

6 6 / What does it bring? Benefits Customer satisfaction De-risk internal projects Cost reduction Tuned to the end-user Innovation

7 7 / What it is not Human Factors 1. Is just common sense 2. Can t be measured 3. Is just for making things look nice 4. Costs too much 5. Is unrelated to system engineering 6. Is a magic trick

8 8 / What it is not Human Factors 1. Is just common sense 2. Can t be measured 3. Is just for making things look nice 4. Costs too much 5. Is unrelated to system engineering 6. Is a magic trick
