In December 2021, the International Organisation for Standardisation (the main ISO body) reported over a million valid ISO 9001:2015 certificates awarded to date around the globe. Since then, this number continues to increase year on year for many and varied good reasons.
But there’s one not so small catch… ISO 9001 might just be the most confusing documents in business history!
The good news is that this series of articles and accompanying free factsheets are purpose designed to:
So, without further ado, let’s dive straight into ISO 9001 Clause 4.2 – Understanding the Needs and Expectations of Interested Parties.
Interested parties are people or organisations that influence how you meet your quality and regulatory requirements. They’re often commonly referred to as ‘stakeholders’, quite simply because they have a stake in your business, whether that’s financial or otherwise.
By incorporating their needs and expectations in to the process, your management system will help you to:
In the specific context of quality management, ISO 9001 Clause 4.2 defines an "interested party" as more than just your customer base. Your customers might be a major source of "significant risk to organisational sustainability if their needs and expectations are not met."
Interested parties are people or entities that:
It’s a sweeping definition that can include an enormous range of entities. So, let’s take a closer look at who these groups of interested parties might typically be.

Your customers and employees are pretty obvious candidates. But your overall range of interested parties needs to be more extensive under ISO 9001 Clause 4.2. You see, your customers and employees are fundamental to your business. But they’re far from the only ones that have an interest or a stake in your past, present and future.
With that in mind, your list of interested parties might include:
Give careful consideration to everyone who could have an impact on your business and whose requirements you must meet. Build a list to ensure you capture all of your interested parties. It’s an effective first step to developing your interested parties register.
A simple list of interested parties isn't sufficient to meet the requirements of ISO 9001 Clause 4.2. This is because a list alone doesn't call for any understanding of the needs and expectations of identified parties.
Bear in mind that any interested party might affect your organisation's ability to provide services or meet legal requirements. So, you need to understand and evaluate:
In simplistic terms, it’s not just that they matter. It’s why they matter.
For instance, your customers buy goods or services from you. Their needs and expectations might revolve around factors like:
On the other hand, your staff’s stake in your business might include factors such as:
Working through your list of interested parties enables you to really drill down into and document their needs and expectations.

The aim of ISO 9001 Clause 4.2 is to solely incorporate interested parties that are relevant to your quality management system (QMS). There isn’t any need to include interested parties that aren’t relevant. So, it’s up to you to decide if the individual requirements of each interested party apply to the QMS or not.
A simple but effective way to do this is to assess the relationship with an interested party in the following contexts:
If you answer yes to any of these questions, the interested party might be relevant to your QMS. In which case it’s worth including them in your analysis, and addressing their needs and expectations within your QMS.
Let’s quickly recap the four fundamental steps of ISO 9001 Clause 4.2 – Understanding the needs and expectations of interested parties -
