Imagine a fire truck pulling up to a home. It is clean, organized, and the firefighters move with confidence as they seem to each know exactly what their job is and where everything is located to get the job done. I asked my coworker who has been a firefighter for nearly 20 years about the efficient and effective movements of the firefighters as they arrive on scene. He confirmed that it is deliberately designed this way and they are trained accordingly. Even the firetruck seats have numbers which are tied to their duties when arriving on scene.
