This book presents, for the consideration of readers and finance professors, a summary of the most important aspects that constitute the framework of project evaluation from the perspective of real options. The tradition of evaluation techniques that has prevailed since the first half of the twentieth century consists essentially of adapting methods of financial engineering. These methods are based on calculating the present value of the relevant cash flows, previously accepted as true or ?expected?. These techniques often ignore the multiple ways in which project managers can exploit the favorable junctures they present due to the many uncertainties that typically accompany real projects. The added value of this managerial flexibility is that of the real options contained in the project. Through concise explanations and selected examples, this text seeks above all to exercise its readers in the development of intuitions and the tools of the subject of real options.
