The main part of the article deals with the analysis of variables affecting the outcome of changes taking place in companies. The empirical survey was carried out using the questionnaire method. The questionnaire was distributed to employees from different types of companies where the changes took place. The survey sample consists of 287 respondents. To test the statistical hypotheses, we used the Spearman’s correlation coefficient. The test hypotheses were processed through the program Gretl. Based on the tested relationship between the variables, a significant relationship between the variables was found - the time needed to prepare and implement the change and the success of the change. Other variables also showed an impact on the final outcome of the change. It has been shown that the process of planning changes, checking upon changes, and the time needed to implement changes have an important role and a major effect on the ultimate success or failure of change in a company.
