In the wash industry, we often spend a lot of time, effort, and resources (money) on equipment and equipment training. While some do show some attention to training an people, the general amount of effort taken to "understand" each individual pales in comparison to the former (equipment).

I've found that the greatest gains in most businesses, especially car washes, are found by education and action revolving around how to treat, teach, and hire on an individual level first, then using these tools to allow for a more cohesive team, and doing it with intention.

The above is a tool to use of a much more detailed document regarding Myers Briggs. Stay tuned for more teaching on this and reach out if you have personal interest about applying this to your wash. Thank you for time and have a wonderful day.
