The CEO of Alerce Austral recommended the development of a training program for its managers in order to increase their knowledge of business administration. A sample of 15 managers was randomly selected and examined by a group of management experts. These determined the general level of knowledge of each participating manager in relation to the topic of the training. Competence and understanding of the topic were rated as "Excellent", "Good", "Regular" or "Deficient". The training program lasted three months. Each of the managers who completed the training was then re- evaluated and re-qualified by the same team of business management experts. The table contains the scores obtained before and after the training. The + sign indicates that the manager improved in their skills and understanding of the topic, while the - sign indicates a decline in skills and understanding of the people after the training program.
