ISO Lab Standard Implementation – Turning Conformance Into Working Systems

The Gap Between Compliance and Reality

For many labs, implementation of ISO/IEC 17025, ISO 15189, or ISO /IEC 17020 begins with good intent. Procedures are written, templates are created, clauses are mapped, and over time a complete system is assembled. On paper, everything appears to be in place. In fact, ISO lab management system standard implementation is often approached as a compliance exercise, but effective systems are built around how laboratory work is actually performed.

In practice, however, the system does not always operate as intended.

This is the point at which implementation moves beyond conformance and into a more meaningful “C”: Control.

Where control starts: Minding the Gap

A system that conforms to a standard is one that meets the requirements of the standard. A working system is one that is used consistently by staff, reflects how work is actually performed, produces reliable and repeatable results, and can be clearly demonstrated at any point in time.

Many labs find themselves somewhere between these two states. Procedures may exist, but are rarely referenced by staff. The same task may be performed differently depending on who is carrying it out. Records may be technically complete, but inconsistent. When asked to explain how the system operates, responses can vary.

 

This gap is not unusual, but it is where most of the real work of implementation sits.

Effective implementation does not begin with the standard. It begins with the laboratory itself. The focus should be on understanding:

• how work is actually being performed;
• how samples are received;
• how testing or calibration activities are carried out;
• how results are recorded and reviewed; and
• how decisions are made.

When this is clearly understood, the system can be aligned to the relevant ISO standard in a way that reflects reality. When implementation is driven primarily by the structure of the standard, systems often become forced and difficult to maintain.

Internal audits are a good way to identify gaps and deal with them. What’s more, they are a requirement of all of the ISO standards for labs. The key is to make them meaningful. We’ve written previously on this very thing!

Consistency

Consistency is one of the clearest indicators that a system is functioning as intended.

When different staff members approach the same task in similar ways, when decisions are made using consistent criteria, and when records are completed in a consistent format, confidence in the system begins to build. Where variation exists without a clear reason, control is reduced.

The point of consistency is not about removing flexibility, but about ensuring that flexibility is applied in a controlled and understood way.

Documentation plays an important role in this, but only when it is properly integrated into the work of the lab. Procedures should reflect what actually happens, and forms should be used as part of normal workflows rather than something brought out only during an audit. When documentation sits alongside the work rather than supporting it, it becomes difficult to maintain and even harder to demonstrate consistency.

Breaking down those document and data silos and integrating them into workflows often involves involvement of the people in the chain of information: the creators, the users, and other stakeholders in the lab, like the Quality people. Take a look at our previous article on Writing Laboratory Documentation That Is Clear, Compliant, and Usable if you need some tips on how to create good documents. Think about how you can use your team to break down the silos and get documentation that sits alongside your work in place. That’s how you can deliver consistency through the tools of documents in your lab.

 

Competence

Competence is another area where implementation is often assumed rather than demonstrated. It’s not just about the ability of a person to do a test or calibration. Competence is about all things done in the lab, including the more administrative tasks.

A well-implemented system makes competence visible. It defines what is required for each role, ensures that staff are appropriately trained and assessed, and maintains clear evidence over time of ongoing competency.

Many labs confine their competency system to just cover testing and calibration activities. And I get why that is: it’s often a massive beast of information to manage and maintain, and extending it into other “administrative” activities in the lab, like audits, sample login, and dealing with non-conformances would further complicate matters. But do you really want someone who doesn’t know how to accept and process samples competently at the start of the lab workflow? Perhaps the problem is with the competency system design, not with the need to assess and record competence.

Remember, confidence in results ultimately depends on confidence in the people producing them, including those in the “supporting” roles.

 

Dealing with problems in implementation

Nonconformances also play an important role in strengthening a system. Rather than being treated as issues to be closed, they should be seen as inputs into improvement. When identified early, investigated properly, and addressed at the root cause, they provide valuable insight into how the system is operating. Over time, this process contributes to a more stable and reliable system.

Many labs will just deal with the problems as they arise and forget to record them as non-conformances. After all, who really wants to be tied up in paperwork?

But the desire not to do paperwork is not a valid excuse for improving the way things are done. Our previous article on why it’s better to be honest and work through the non-conformance process highlights many of the barriers people face in working through and solving problems in the lab and suggests ways to overcome these barriers. Hint: it’s best to work with a team rather than as a solo operator.

One of the more common challenges in implementation is over-complication. Systems can gradually become more complex as additional procedures, controls, and layers are introduced, and NATA Assessors make those helpful suggestions. While each addition may be well-intentioned, the cumulative effect can make the system harder to use and more difficult to apply consistently. In most cases, a simpler system that is clearly understood will perform far better than a complex one that is not.

That’s why it’s important to deeply review processes and procedures and for internal auditors to be alive to complexity and bottlenecks in the processes they audit. These activities of review and audit are not meant to be box-ticking exercises to say they were done. They are valuable opportunities to make improvements and smooth out implementation problems.

 

The final word

A well-implemented ISO 17025 system is usually easy to recognise. Staff are confident in how they carry out their work. Documentation aligns with practice. Records are consistent and complete. Processes are repeatable. Perhaps most importantly, the system works every day, not just during an assessment.

The transition from compliance to control does not come from adding more to the system. It comes from aligning the system with actual work, simplifying where possible, reinforcing consistency, and ensuring that processes are understood and applied. This is where ISO lab management systems standards begin to deliver real value.

Implementation is often seen as a milestone. In reality, it is the starting point. The goal is not to build a system that satisfies the standard, but to build one that supports the laboratory in producing reliable, consistent results as part of its normal operation. When that is achieved, compliance becomes a natural outcome of how the laboratory works.

 

If your laboratory has an ISO lab management system in place but it is not consistently working in practice, MAS Management Systems can assist in aligning compliance requirements with day-to-day operations in a practical and structured way.

FAQs

What is ISO 17025/ ISO 15189/ ISO 17020 implementation?
ISO 17025/ ISO 15189/ ISO 17020 implementation is the process of building and applying a laboratory quality system that ensures competence, consistency, and valid results.

Why do ISO 17025/ ISO 15189/ ISO 17020 systems fail in practice?
Systems often fail when they focus on documentation rather than on how work is actually performed, leading to inconsistency and poor usability.

How do you improve an ISO 17025/ ISO 15189/ ISO 17020 quality system?
Improvement comes from aligning processes with real work, simplifying documentation, reinforcing consistency, and using nonconformances as inputs for improvement.
