Dear all, My company is a semiconductor company has a few locations in US and Asia (Site A, B, C). Only one site (say site A) in US is ISO9001_2015 certified. This site (site A) has all ISO9001 processes: Development, Sales/Marketing, production, testing/inspection, shipping/receiving, QA, outsourcing, planning, etc. Some staff located in site B and C also support work on the product & process of Site A. However site B & C are not ISO9001 Certified and not in the scope of the certification. Although they follow the same quality system and subjected to yearly internal audit. How should we refer to these two sites? As external service provider? and how should we control it according to ISO9001_2015? Thank you for your attention!
