This is my first post under ISO 9001:2015 head. English is my second language. We are currently planning to kick off a internal project to transition to revised version i.e. ISO 9001:2015 after Mar'16. Our existing certificate is valid till Mar'17 and due for re certification audit. Seek guidance on queries below: 1. Can we combine re-certification audit on existing version and certification audit on ISO 9001:2015 by Mar'17 ? Quite positive that our systems will be ready for the requirements as in ISO 9001:2015. 2. Do we need to consult for external professional services for the transition project ? Suggest few options categories ? 3. If we want to do it utilizing our internal resources, can you suggest right approach, steps ? I mean with reasonable cost guidance tools, checklist or books on implementation. Can anybody share WBS project steps for ISO 9001:2015.
