Below is our downtime log for [plant/line] for [month]. Each row has date, machine, minutes lost and a free-text reason written by operators in English or Hindi. Group the reasons into clear categories such as tooling, material, electrical, changeover and operator. Use our categories if given: [categories]. For each category show total minutes, the machines most affected and three example entries. Then list the five most repeated specific causes. Show which rows you could not categorise.
