What is a company? What are its objectives? Why start it? how to start it? The best way to understand in the shortest possible time how a business, any business, works is to start one. The seminar lasts 4 days for a total of 20 hours; the first 15 hours will be carried out remotely, the last 5 in the presence, necessary for the presentation of the projects developed by the individual groups set up for this purpose. With the "learning by doing" methodology, the general conditions of the context will be addressed first in order to identify the area/sector of greatest attractiveness for the creation of one's own start-up, the value offered and the conditions and methods for the realization of this value. The approach used is that of the Business Model Canvas with exercises and case studies both for the development of the business idea and for its economic sustainability. Due to its specificity, the seminar is interactive and aims to transform each working group into a start-up to be brought into competition on the last day of the seminar. The speakers come from the business world.
