mass production custom production automated production assembly line production
I gave my students this multiple choice question: Ann makes hats for people. She has each person select the fabric and a hat style before she makes the hat to fit the person's head size. Which type of manufacturing system is Ann most likely using to make hats?

Only one answer is correct among these 4 choices:
- mass production
- custom production
- automated production
- assembly line production

Could you tell me which one is correct?

custom production
