ISO 19011 is an international standard that sets forth guidelines for management systems auditing. The current version is ISO 19011:2018. It is developed by the International Organization for Standardization.
Originally it was published in 1990 as ISO 10011-1 and in 2002 took the current ISO 19011 numbering.
The standard offers four resources to organizations to "save time, effort and money":
|1990||ISO 10011-1 (1st Edition)|
|2002||ISO 19011 (2nd Edition)|
|2011||ISO 19011 (3rd Edition)|
|2018||ISO 19011 (4th Edition)|
