Industrial engineers perform a method called "time and motion study" to increase efficiency at manual processes. In the age of digital transformation, they still do it manually by using a simple stop-watch, which costs huge time and money for the industry. Additionally, since this is a sampling method, they generally gather false data.We automized the time and motion study with AI-based video analytics. In this way, engineers can save time and improve manufacturing lines better with true data. It costs much less to the industry and allows them to find new alternatives for improving efficiency.
