Creativity has become the guiding principle of economy and society: employees, managers, companies, and entire industries must be creative to compete in the international market. Creativity is not an abstract concept; it is a social practice, an entrepreneurial process, and a personal trait all in one. People are creative every day; they think imaginatively, solve problems, and create new things. This work presents the economic and organizational aspects of creativity and innovation in an understandable way. Similar to an onion model, creativity is analyzed step by step, starting from the individual, through places of emergence and social integration, to processes. The reader thus gains an overview of theories, methods, and the practical application of creativity.
