10 Reasons Why You Need ISO 9001 Certification

14 January 2021


In this article we'll take a close look at the benefits of ISO 9001. Drawing on case studies published by the International Organization for Standardization and decades of our own experience, we'll give real world examples of how ISO 9001 impacts on customer and employee satisfaction, quality and productivity, sales revenues, and company reputation. In short, we'll give you some very good reasons why ISO 9001 is right for your organization.

We'll start by examining the internal benefits of ISO 9001, then move on to the marketing benefits before concluding with a discussion about increased profitability.

The Internal Benefits of ISO 9001

In 2014 the International Organization for Standardization published a series of case studies explaining how companies in more than 20 countries worldwide benefited from ISO 9001. The survey, Economic Benefits of Standards, showed that frequently the most significant benefits were internal rather than marketing. They included:

Improved customer satisfaction

More dedicated employees

Better quality products and services

Increased efficiency

Reduced risk

These points broadly confirm our own experience. As we've made clear in other articles, many people don't realize that the most important benefits of ISO 9001 may be operational rather than marketing. ISO 9001 was designed as a tool for companies to improve their operations and bottom line; certifications and marketing benefits came later.

Improved Customer Satisfaction and Loyalty

Customer satisfaction is a key focus of ISO 9001. The standard requires that your organization not only determines if customer requirements have been met but also monitors your customers subjective perception of it. This almost inevitably ensures that a properly implemented quality management system will deliver customer satisfaction.

The importance of meeting – and indeed exceeding – customer expectations can't be overstated. Satisfied customers will be retained: they will become repeat customers and eventually develop a strong sense of loyalty. In due course they may generate additional revenue streams though written or word of mouth recommendations.

A happy, engaged, well-trained and competent workforce is a productive workforce. Employee satisfaction is a major benefit of ISO 9001.

In our article, How ISO 9001 Benefits Employees, we discussed how a robust ISO quality management system can impact positively on staff. Benefits typically include:

Empowered employees
The feeling of being empowered plays a major role in boosting job satisfaction. Involving and engaging employees are among ISO's core principles, and ones that contribute greatly to a happy, motivated workforce.

Employee training / Professional growth
Another key tenet of ISO 9001 is employee training. Employees always respond favorably to training programs, staff reviews and evaluations, additional responsibilities, and opportunities for career development. Employees enjoy knowing they're part of a company that's moving forward and their career is in safe hands.

Better understanding
The ISO standard's strong focus on customers and customers' needs helps staff better understand how their actions affect the end product or service, and how their actions can help pave the way to improvements.

Greater employee engagement
ISO 9001 fosters a strong supportive culture that engenders enthusiasm, engagement, and increased productivity.

A happy, engaged, well-trained and competent workforce is a productive workforce. In this respect, employee satisfaction is a major benefit of ISO 9001.

Better Quality Products and Services

Better quality is what's typically associated with – and expected from – ISO 9001 and certified companies. It is in fact one of the key benefits of implementing the standard. The following case studies, published by the International Organization for Standardization, illustrate this point very well.

Festo, Brazil

A thorough implementation of ISO 9001, combined with organizational, managerial and technical improvements, was the driver behind the increased quality and productivity in manufacturing, allowing Festo Brasil to become a world-class producer for a significant part of Festo's global portfolio.

Petra Engineering, Jordan

With the help of the ISO 9001 quality management system, Petra was able to ensure tight control over its production processes, helping to build up its reputation as a high-quality producer.

The above case studies are quite typical. The 9001 Standard incorporates the Plan-Do-Check-Act (PDCA) cycle. Once this is integrated into a culture that fosters continuous improvement, organizations can ensure that their processes are effectively managed, and opportunities for improvement can be determined and acted on.

Increased Efficiency, Fewer Mistakes and Less Wasted Time

Several of the Standard's requirements result – directly and indirectly – to improvements to operational processes, both in terms of efficiency and reliability. For example, the requirements on employee competence, updated documentation and supplier controls all play a role in achieving less scrap, waste and rework. The process approach and risk-based thinking, both of which are fundamental concepts of ISO 9001, contribute to a better and more efficient integration of operational processes with less room for error.

VINAKIP, Vietnam


The quality management system based on ISO 9001 helped VINAKIP define its business processes clearly and share information regarding product characteristics, key activities, performance indicators and good practice. This resulted in the overall improvement of processes, a reduction in product variety and better cooperation with suppliers, leading to higher-quality inputs, less waste and a lower number of repairs.

PT Wijaya Karya Beton, Indonesia

Under a unified quality management system based on ISO 9001, the operations of different business functions were integrated and optimized. Particularly relevant are the time savings in the engineering business function due to the dissemination of standardized information (e.g. for material specifications, process specifications and standardization of the product). This information is also used to define better working instructions and operational procedures, leading to the increased efficiency of several production processes. Such developments have also helped to achieve higher product quality, boosting both customer confidence and sales revenues.

Risk-based thinking is an important component of the 9001 Standard. To quote from the Standard itself: "Risk-based thinking enables an organization to determine the factors that could cause its processes and its quality management system to deviate from the planned results, to put in place preventive controls to minimize negative effects and to make maximum use of opportunities as they arise."

The Standard emphasizes that risk should be identified and mitigated throughout the entire organization. And it's not only top management that's responsible – all employees need to be involved. Once a culture of risk awareness has been established, and once the required controls are in place, organizations will benefit from reduced overall risks.

10 Reasons Why You Need ISO 9001 Certification

An ISO 9001 certificate is a superb marketing tool. Displaying it on your website or company documents speaks much about your commitment to quality products and services, customer and employee satisfaction, and the overall efficiency of your operations. Marketing benefits can be summarized as:

Increased sales and market share

Improved relationships with suppliers

Easier access to international markets


As valid as marketing benefits are, we need to repeat that ISO 9001 was conceived as a tool for companies to improve their operations, and the most important benefits are often operational (ie, internal) rather than marketing.

Increased Sales and Market Share

The International Organization for Standardization informs us that ISO 9001 certification does indeed enhance financial performance, and this is achieved mainly through increased sales. This is perhaps unsurprising after considering the internal benefits discussed above. However, there is more to it. The ISO 9001 certification mark is the world's most recognized indicator for quality, providing certified companies with a clear advantage over their competitors. It's for this reason that certified companies miss no opportunity informing potential customers about their 9001 credentials.

Fulfilling a Sales Prerequisite

The ISO 9001 Standard requires certified organizations to implement criteria for the selection of their suppliers. While organizations are free to determine their own criteria, a trend has emerged among larger enterprises to stipulate ISO 9001 certification as a prerequisite. Also worth noting here is that many government agencies are increasingly replacing their own quality standards with a requirement for ISO 9001 certification.

When a supplier is bidding for a contract, it's often a prerequisite to be ISO 9001 certified in order to be considered. This is especially true when dealing with government departments.

Penetrating new markets is seldom easy, especially if your company or brand is little known outside its country of operation. Barriers to entry may include uncertainties about your products and services, or doubts about your ability to deliver in accordance with schedules. ISO 9001 registration overcomes these and other hurdles by acting as a badge of quality that's respected globally. It tells potential customers that your company can be trusted and your products or services will be among the best on the market. Equally, the ISO certificate dispels concerns about internal factors such as efficiency, wastage, and ethical employment practices.


The ISO certificate is a badge that deserves to be shown off with pride. It increases your company's reputation. We already discussed the resulting increase in sales. But your reputation can also attract more highly skilled employees, and increase the potential for partnerships or even acquisition. There are countless ways that ISO certification and the cachet it generates can directly and indirectly benefit your organization.

Increased Profits

When internal and marketing benefits are realized, increased profitability is the outcome. But that's not the end of the story. The International Organization for Standardization publishes a Standard, ISO 10014, that presents guidelines on how to optimize the financial and economic benefits of ISO 9001.

And there's more. An extremely important yet often-overlooked tool for improving your company's processes is the ISO 9001 internal audit. We encourage you to take a fresh look at internal audits and learn to see them as one of the most powerful elements of your quality management system. Used properly, they'll help you not only to spot inefficiencies, but to identify improvement opportunities that may lead to significant cost savings and increased profitability.


ISO 9001 is the world's most popular quality management system. According to recent data, more than a million organizations worldwide are certified, spanning all sizes across a broad range of industries. The benefits are numerous and have a profound impact on both company culture and the bottom line.
