As a result, it is emphasized that the vast majority of respondents realize change control, mainly by hand, but most of them do not analyze the impacts of changes schemes. And present data that may be useful for decision making by industry representatives and government, expected to expand the studies to a larger number of companies, thus increasing the scope of this research and, consequently ensuring greater reliability of information.
