McDonaldization is a term used by sociologist George Ritzer in his book The McDonaldization of Society (1993). He explains it occurs when a culture possesses the characteristics of a fast-food restaurant. McDonaldization is a reconceptualization of rationalization, or moving from traditional to rational modes of thought, and scientific management. Where Max Weber used the model of the bureaucracy to represent the direction of this changing society, Ritzer sees the fast-food restaurant as having become a more representative contemporary paradigm (Ritzer, 2004:553). In contemporary society, the concept of McDonaldization is gaining attention in different aspects such as culture. McDonaldization thesis in cultural version is a comparatively recent idea of the world wide homogenization of cultures. The process of McDonaldization can be summarized as the way in which "the principles of the fast-food restaurant are coming to dominate more and more sectors of American society as well as of the rest of the world."
Ritzer highlighted four primary components of McDonaldization:
- Efficiency – the optimal method for accomplishing a task. In this context, Ritzer has a very specific meaning of "efficiency". In the example of McDonald's customers, it is the fastest way to get from being hungry to being full. Efficiency in McDonaldization means that every aspect of the organization is geared toward the minimization of time.
- Calculability – objective should be quantifiable (e.g., sales) rather than subjective (e.g., taste). McDonaldization developed the notion that quantity equals quality, and that a large amount of product delivered to the customer in a short amount of time is the same as a high quality product. This allows people to quantify how much they're getting versus how much they’re paying. Organizations want consumers to believe that they are getting a large amount of product for not a lot of money. Workers in these organizations are judged by how fast they are instead of the quality of work they do.
- Predictability – standardized and uniform services. "Predictability" means that no matter where a person goes, they will receive the same service and receive the same product every time when interacting with the McDonaldized organization. This also applies to the workers in those organizations. Their tasks are highly repetitive, highly routine, and predictable.
- Control – standardized and uniform employees, replacement of human by non-human technologies
With these four principles of the fast food industry, a strategy which is rational within a narrow scope can lead to outcomes that are harmful or irrational. As these processes spread to other parts of society, modern society’s new social and cultural characteristics are created. For example, as McDonald’s enters a country and consumer patterns are unified, cultural hybridization occurs.
Irrationality of Rationality 
Ritzer also outlines Irrationality of Rationality as a fifth aspect of McDonaldization. "Most specifically, irrationality means that rational systems are unreasonable systems. By that I mean that they deny the basic humanity, the human reason, of the people who work within or are served by them." (Ritzer 1994:154)
Ritzer introduces this during Chapter Two (The Past, Present, and Future of McDonaldization: From the Iron Cage to the Fast-Food Factory and Beyond) of his book "The McDonaldization of Society" in the sub-section Irrationality and the "Iron Cage." He states that "Despite the advantages it offers, bureaucracy suffers from the irrationality of rationality. Like a fast-food restaurant, a bureaucracy can be a dehumanizing place in which to work and by which to be served." In short; "settings in which people cannot always behave as human beings"
He further states that beyond dehumanization further irrationalities emerge; including the inefficient masses of red tape, over quantification leading to low quality work, unpredictability as employees grow unclear about what they are supposed to do, or the loss of control due to other inadequacies.
Many corporations have been making an effort to deny the rationalization of McDonaldization. Efforts are related to focusing on quality instead of quantity, enjoying the unpredictability of service and product and employing more skilled workers without any outside control. Protests have also been rising in nation-states in order to slow down the process of Mcdonaldization and to protect their localization and traditional value. 
In the book "The McDonaldization of Society" by George Ritzer, he discusses and provides his perspective of the modern world in the view of fast-food restaurant. Another interesting political theorist who provides a negative view on the atmosphere that Mcdonaldization has created is Hannah Arendt. She is a political theorist who highlights the corruption of human world from rationalistic feature (as discussed in Ritzer's book)in her reporting of the Eichmann trial for The New Yorker Eichmann in Jerusalem: A Report on the Banality of Evil. She indirectly argues the need for humane insight in order for de-McDonaldization to slowly take its place. Pippa Norris and Ronald Inglehart question the extent to which McDonaldization has really been occurring in their book Cosmopolitan Communications: Cultural Diversity in a Globalized World, finding national cultures resilient in the face of globalization.
Also some local case studies show how the rational model of McDonald's adjust to local cultural preferences and the result is a diminution of the original McDonald's product. In fact, the more the company adjusts to local conditions the more appeal of the specifically American product may be lost. At the end of the day, McDonald's is a contributing factor to glocalization.
Examples of Mcdonaldization 
Junk-journalism, defined here as inoffensive and trivial news served up in palatable portions, is an example of Mcdonaldization. Another example could be McUniversities, which features modularized curricula, delivering degrees in a fast-track pick-and-mix fashion to satisfy all tastes. The diminished quality of these products can only be disguised by extensive advertising which constantly repackages them to look new. 
Response of McDonald's 
The response from McDonald's, expressed by its representatives in the United Kingdom, is that Ritzer, like other commentators, uses the company's size and brand recognition to promote ideas that do not necessarily relate to the company's business practices.
