We have 2 certifications: ISO 9001:2015 and ISO 20000. One of my auditors said we may use ISO 9001:2015 that covers all processes in ITIL also, can you help us with that? I mean, is it similar, what should we do?
A Service Management System (SMS) based on ISO/IEC 20000-1uses more detailed and industry-specific requirement. Yes, we can argue that same requirements are also included in the ISO 9001:2015 QMS - although with a more generic approach i.e. on higher level. So, if you want to manage your services, SMS is right „tool“ for you.
