What is a work exercise I can do with my managers to test this theory and raise awareness of it?

To test the theory and raise awareness of human-centered design, you could conduct a workshop with your managers. Here's a simple exercise:

1. Divide the managers into small groups and give each group a common object (like a stapler, a coffee maker, or a mobile app).

2. Ask them to list the flaws in the design of the object from a user's perspective.

3. Then, have them brainstorm ways to improve the design to make it more user-friendly.

4. Finally, each group presents their findings and proposed solutions.

This exercise will help your managers understand the importance of considering the user's perspective in design and how it can lead to more effective and efficient products or services.
