Businesses can rely on ISO standards to maintain consistent quality in what they do. If you’ve ever asked, “What are the 3 quality levels of ISO?”, you’re likely referring to ISO 9001, ISO 9002, and ISO 9003—once distinct quality assurance models. The blog details the different steps, the way they evolved, and which one is still useful for companies now.
The ISO, or International Organization for Standardization, ensures that industries around the world work according to high-quality, secure, and efficient standards. In particular, the standards within the ISO 9000 family focus on quality management systems (QMS) that help companies provide the same excellent services and meet what customers ask for.
ISO standards guide companies in setting up proper processes, keeping records, and monitoring their progress in quality assurance.
There were three quality assurance models introduced in the first version of ISO 9000. ISO 9001, ISO 9002, and ISO 9003. Even though only one of these is used today, learning about all three gives insights into how quality assurance has changed throughout the years.
More companies follow ISO 9001 than any other quality management standard. It describes what is needed to set up and operate a quality management system, including:
The standard fits any organization, whether it is big or small, and whether it operates in a particular field. A manufacturing business may hire an ISO 9001 to organize product design, development, and testing to reduce the number of flaws and impress customers.
ISO 9002 was made for companies that did not do product design but took part in production, installation, and customer service. It did not cover design control area, yet it kept processing work and quality aspects.
Though not used anymore, ISO 9002 was at one point used by logistics and warehousing companies focusing on product handling, but not its development.
ISO 9003 was developed to handle only the final checks and tests of the products or services provided. The goal was to show that requirements were met in the final outcome, instead of improving how things were done.
Initially, businesses that used this were mainly firms at the tail end of the process, including distributors and small service providers. Yet, organizations are moving away from the standard in favor of the substantive ISO 9001 standard.
No, ISO 9002 and 9003 are no longer in use, as their standards were changed and included inside ISO 9001. Right now, the only ISO 9000 family guideline in use is ISO 9001.
Businesses hoping for certification or to create internal quality systems should look towards ISO 9001.
With the previous versions being obsolete, ISO 9001 takes their place and is now the standard for quality. It suits:
For any business providing products or just offering services, ISO 9001 can be suited to your needs.
Using ISO 9001 as a quality management system can lead to many different business benefits.
A small business relies on ISO 9001 to enhance client satisfaction and control chaos when the company grows.
Logistics companies work according to ISO rules to ensure that their deliveries are more accurate.
A manufacturing plant decreases faulty products and makes them easier to track by setting out its processes as required by ISO 9001.
This blog has discussed what are the 3 quality levels of ISO with clear explanation. When ISO quality levels were first created, there were three options; today, ISO 9001 covers and goes beyond the aims of those models. If a business understands its role, it can manage operations better, deliver top products, and please its customers. No matter if you’re in industry, services, or logistics, ISO 9001 helps you maintain your quality over the years.
No. When the ISO 9000 family of standards was updated, ISO 9002 and ISO 9003 were officially removed and merged into ISO 9001.
Any business, big or small, in production or services, can use ISO 9001 to improve how they handle processes and become more credible.
Yes. ISO 9001 covers the needs of service companies. It assists in providing faster service, keeping track of customer happiness, and improving company procedures.
