You may be impressed with different types of ISO 9001 companies, because they are guaranteed with a seal and standard of excellence that not all organizations have. But you will also probably be more impressed at what these companies went through (and continue to go through) in order for them to maintain such a standard of excellence.
This is because many organizations go through a lot of things just so they can be said to have passed the ISO 9001 standards. First off, these ISO 9001 standards companies needed to determine the different customer requirements as well as create systems in order for them to communicate with their customers regarding product information, different types of inquiries, contracts, feedbacks as well as complaints, and orders. When they developed their new products, they needed to show their own detailed plans of the stages of development, along with the appropriate testing of each stage. These ISO 9001 standards companies needed to test as well as document whether their products or outputs were able to meet the design requirements, the regulatory requirements and the needs of the users.
They also need to regularly review their performance by means of internal audits as well as countless meetings in order to determine if the quality system is indeed working and what sorts of improvements can be made for such improvements to happen. All these and more are the things that such companies have to go through in order to be part of the small but widening group of ISO 9001 standards companies.
