Who can apply?
Manufacturing, service and public organisations of different sizes can use ISO 9001. A small business is not excluded by its legal form or workforce; the scope must describe its actual activities and sites.
What must be ready?
Define processes, responsibilities, customer requirements and quality objectives. Keep operational evidence, supplier controls, risk records, internal-audit results and management reviews that reflect real practice.
How is assessment planned?
Sites, shifts, personnel and readiness affect time and cost. Assessors examine implementation and findings; the certification decision is separate. Check the provider’s relevant scope and clarify surveillance and changes in writing.
