More resources to acquaint you with ISO and the certification process.
The International Organization for Standardization (ISO) is the world's largest developer and publisher of international standards. Industry best practices from around the world are whittled down and compiled into internationally recognized standards.
Pursuing certification to a standard can change your competitive position and even your perspective on how to manage a business.
The ISO 9001 standard specifies requirements for a Quality Management System where an organization needs to demonstrate its ability to provide product that consistently meets customer, regulatory and statutory requirements. It lists provisions for controlling and documenting the organizational processes that can affect quality.
This isn't a product specific standard; ISO 9001 is deliberately generic and process oriented, and can be applied across industries and sectors. It describes a management system, not a quality control system, although controlling quality is the natural result of good management. If your goal is tighter control over manufacturing with more predictable output and company-wide quality assurance, ISO 9001 is a leap in the right direction.
