Even though drive-in restaurants were already popular in America in the 1950’s, they were not as successful as the fast food restaurant owned by the MacDonald brothers. List three reasons for this lack of success.

1- There was no standardization strategy for hamburgers that would maintain the same quality for all orders.

2- There were not enough employees and properly trained to meet the demand of orders.

3- There was no well-defined business model that could expand to become a franchise.

McDonalds's restaurant revolutionized the business world by adopting the standardization of its snacks, which made the business more structured, in a model that, through innovative sandwich assembly devices, made them more standardized, and accelerated the assembly and waiting time for the order .

The division of the processes of assembling snacks and milkshakes into simple and repetitive tasks led to the creation of a production line for the fast-food restaurant in a totally innovative way, which made it possible to meet demand, more quickly and reduce costs. and waste, which made it possible to sell its business model to other locations and then create a profitable franchise that is a successful model to this day.
