Robots welding in a production line find iso certificateWe see our charter or vision is to promote standards in industry.  Over and over we see the effect when companies adopt the use of standards within the operation of their organization.  Although the process to take a standards approach may seem daunting, the effect, if implemented correctly, is a boost to the bottom line: reduced cost, improved productivity, and a staff trained to work toward common goals.

Standards do not impose a methodology to operate a business; instead it focuses on accountability, reproducibility, risk management while introducing ways to document the operation.

Our vision is to help with these goals.


Our mission is to provide valuable information services to industry that promote the adoption and improvement of their management systems.
