Why is it important to have standards like the ISO or ANSI and which is in your opinion the better standard?

either of them has a predefined conditions to get it. But it is not the only factor to indicate that a company has effective quality management. I think ISO is more important.

Thank you for the invitation 

I'll wait to find out the answer of specialists

Standard Institute American National Standards (ANSI) 

International Organization for Standardization (ISO) 

It does not have is the best of the countries apply the standard American countries and apply the criterion of the International Organization

Mr. Georgei Assi answered the question what ISO and ANSI stand for 

ISO is the International Standard Organization - it sets a standard followed by a large part part of the world and utilizes the metric system in machines, gives us a standard of screws .. motors ... only exceptions are in the piping and aircraft industry; businesses are given a standard under ISO9001 how to run a facility ... 

ANSI is the American National Standard ... mainly used in the US ... Canada has changed to ISO in many areas.

ANSI uses mainly inch as units ... is the opposite when drawing views in drawings.... has many different motors .. screws ...

Still used in pipes (Oil and Gas Industry) and for the thickness of material in the aircraft industry.

In my opion the ISO is the better system .. less confusing and better organized.  

The standards prescribes minimum quality limits to be maintained in the product.

Hi Elke,

Thank you for your invite.

Apologies but I do not know what ISO and ANSI means.

I'm hoping for other colleagues to answer so I can learn more on this subject.
