How to analyse the economic/financial health of a company? Legal entities have a life and need daily care to keep up in such a competitive market. No balance sheet? No DRE? Do not know the importance and the obligation of these statements? Imagine a diagnosis without the "tests" to identify where the problem is. Do you think it is feasible for a "doctor" to define treatment without first investigating where the problem comes from? The economic/financial analysis plays the role of "exams" so that decision making is more assertive. Keywords: Economic/Financial Analysis. Financial indicators. Restaurants.
