“I am a new person in charge of Environment and Quality tasked with implementing the ISO 9001:2015 and ISO 14001:2015, which the company is already certified against. My confusion is the meaning of quality in a hydropower setting.
Look into clause 4.2 of ISO 9001:2015. Determine the relevant interested parties, the stakeholders, and determine their requirements and expectations. Quality in most organizations is about satisfying requirements and expectations of interested parties, quality is about having hydropower availability when expected, quality is about minimizing costs. Model the functioning of your organization as a set of processes that want to deliver satisfied interested parties, availability, and efficiency.
“2. How do I easily integrate both management systems since they are both being manned by one person?”
You can compare both standards and realize that there is a lot in common. When I implement integrated management systems, I describe the organization as a set of processes that deliver the purpose, the mission of the organization. Then, after an initial environmental assessment, I determine what processes or activities must be improved or standardized in order to eliminate or minimize significant environmental impacts. That translates into making changes in some of the processes. Concerning top management, the policy, objectives, context, interested parties and part of the risks are common.
