Evaluation of Decision Effectiveness Over Time

In this paper, the results of my research are presented that was carried out on a large sample to investigate how people look back at their previous business decisions. After a short literature overview, considering the role of time, the paper deals with the primary research: how people judge their decisions in the short term and in the long run, that is, how confident they are that the right one was chosen applying the available knowledge of facts and conditions connected with or relevant to their situation. Using statistical methods, comparisons were made, for example, based on the respondents’ gender, so it turns out whether gender has an influence on self-confidence or on exactness of judgement. Does the position, that is, the rank matter? Can it be assumed that the farther one gets up the corporate ladder, the more certainty can be observed about their decisions? And what about educational level? Does it influence judgement in a decision? Those who do not regret their decisions after a while, that is, after the original decisions were made, while being in possession of the information available later, can be more successful in business because they made the best decision. Trying to identify such characteristics or factors can be an advantage in the business life.
