Video analysis is an extremely powerful tool. Coaches in a wide variety of sports and working environments use video as a tool for motivating and achieving improvement.
Taking video of operators during operation and analyzing it with the operator can help them to see and understand any opportunities that may be available to improve upon.
Operators get to do analysis of their own video with help of instructors to identify areas for improvement.
This helps operators to learn to do self assessment and see a visual of their opportunities.
