Mandatory clauses

Answer;

All clauses in the standard are mandatory, however there are some clauses that may be inapplicable to your company and such clauses may be excluded form the scope of the QMS.

In the previous version of the standard, the exclusions could be made form the clause 7. In the 2015 version of the standard, the company may exclude any clause that it finds inapplicable to its business, in practice, the clauses that can be excluded are 7.1.5 and any sub-clause form the clause 8.

For every exclusion made form the standard, the company must provide justification in a form of documented information. For more information, see What clauses can be excluded in ISO 9001:2015? https://advisera.com/9001academy/blog/2015/07/07/what-clauses-can-be-excluded-in-iso-90012015/2015/
