Efficiency is the optimal method to ensure the transition from one state to another. The smaller operations in the process the better systems are McDonaldizied. As an example - instead of the traditional courtship people increasingly prefer online dating, because it is faster and easier. Predictability is a guarantee that all products and services are the same at any time and in any place. Coming to any part of the globe, people expect the same product in a local McDonalds as in the McDonald's close to home. Calculability means an emphasis on quantitative aspects of products sold (serving size, cost) and services (the time required to produce something). Here an emphasis lies on quantitative indicators. The example is a pizza delivery speed, as it affects the quality of the food. The downside is fatal accidents involving young Pizza Man.
Finally, the control over the people using nonhuman technologies is shown by the example of control over customers in McDonalds, customers are given the prompts, e.g., they see garbage cans, especially at the output. At first glance, these principles are so self-evident that it is not impossible to notice them: striving for maximum efficiency, one obviously has to count his/her efforts, trying to act in a predictable manner and implemented in this regard, the necessary control. A closer look allows seeing a more complex picture here. For example, the principle of calculability - it obviously requires really accurate calculation from those who take it on board, which in turn means that: 1) it must be calculated, which also allows the other three principle expressed quantitatively (relative to time and place, and etc.); 2) anything that is not amenable to precise calculation (and it may be very important things), should be discarded, thus remaining outside the planning; 3) because the payment took place, then it should be a guide to action for strict compliance; 4) that, in turn, implies hierarchical organization of action, when the initiative belongs to those who are 'above', and the other should play the role of an obedient executor (Ritzer, 2014).
