Integrated checklist for ISO 9001:2015 and ISO 14001:2015

First, I can only help you develop a checklist based on the standards, you should not forget that auditing compliance against internal procedures and effectiveness against management systems objectives is very important.

Start by determining which ISO clauses are related with the quality department. For example:

• 9001 – 8.6, 8.7, 9.1, 9.2, 10.2, 10.3
• 14001 – 6.1.2, 8.1, 8.2, 9.1, 9.2, 10.2, 10.3
• Some organizations may include also clauses 6.2 and 9.3.

Now, think about what you want to know regarding those clauses. For example:

• Are quality control activities being performed according to plan?
• Is nonconforming product segregated, treated and recorded? Are corrective actions developed?
• Is process monitoring, analysis and evaluation performed according to plan?
• Is the audit program executed? Are audit results available?
• What environmental aspects are related with the quality department?
• Are environmental operational controls in place at the quality department?
• And what about preparedness and emergency situations in the quality department? Are prevention measures in place? Are response measures in place?
• Any simulation done? Any emergency happened? What was learned?
