Let begining with the manufacturing style of Subway, the sandwich store offers more choice to customers. Order placement involves customers picking and choosing the ingredients they want. Salespersons standing behind the counter – and not kitchen staff behind the scenes – themselves assemble the sandwich in front of customers. For example, a customer Tom who orders a Veggie Delite Sub can ask for double portions of all ingredients such as tomato, cucumber, onion, green peppers, olive, pickle and jalapenos. Whereas another customer Jane could order the same Veggie Delite Sub but opt for single portions of tomato, cucumber and green peppers and skip all other items.
This makes Subway a good example of Assemble to Order style of manufacturing.
