As mentioned earlier, the audit is not a single operation. It is a tool to improve quality and quality can
always be improved. So the idea of the audit cycle is that is is an ongoing process, which means that audits
are performed from time to time. But audits should should be connected to each other. Improvement
starts when the results are compared. Also, the auditors become more skilled and maybe find potential
improvements they did not see earlier. The goals can also change after a while, maybe because of new
technical achievements or simply because of an environmentally change. If goals are changed the whole
audit process has a new basis and needs to be repeated.
