In addition, inferential statistics can help the quality control engineer make deductions from the data that can be applied to refining business processes so that they better meet quality goals. Statistical approaches to quality control, however, are not without problems and continuing development of new tools is needed. An example of an approach to statistical quality control is Six Sigma which attempts to keep processes within specification 99.9999997 percent of the time.
