I went back to the original sources: guidance documents from the FDA, standards from professional organizations, and everything I had learned from real-world experience. The expectations told you what needed to happen, but they didn’t say much about how to make it all work. I realized that what was missing wasn’t knowledge. It was something to help it make sense to the whole team.

I started sketching out a framework that could bring clarity to the work without oversimplifying it. Something solid. Practical. Easy to teach. A word came to mind that captured it: CAGES. At first, it was just shorthand for the four essential steps: Claims, Approach, Gathering Evidence, and Summary. But the name stuck with me for another reason.

When I was four years old, I lost my mother. One of the few clear memories I still hold is from April Fool’s Day when she played a joke on my father. She told him a bird was in the basement. Because I was too little to follow them downstairs, I had to wait at the top of the steps. I still remember her calling out, “April Fools!” and me repeating it gleefully from above. My father was a young Army officer at the time, uniform and all, and he had rushed into action thinking there really was a bird flying loose.

It was just a joke. But if the bird had been real, the worry would have been justified. What could it knock over? Where would it leave a mess? How long would it take to clean up, and how much would it cost?

Fast forward to today, and I find myself working with people I admire; smart, capable professionals in the life sciences who I like to refer to as Medical Marvel Makers. They’re developing products that improve and extend lives. But they also have something to watch out for.

Their version of the bird? Let’s call it the Fregata Delandi Aldabra. Or for simplicity, the FDA.

Without warning, the bird slips into the facility, flaps through the process, and leaves behind uncertainty. No one knows how it picks its targets, but suddenly everyone’s trying to assess the damage.

What did it seek that was missing? What did it find that left it confused? How do we keep a bird like that from roaming freely through our systems?

CAGES®.

It’s more than a metaphor. CAGES® is a validation framework designed to bring clarity to your process before problems take flight. Here’s what each part of the acronym stands for:

Claims

Start by defining what the process or system is expected to do. This includes identifying which outcomes are essential and what counts as success or failure. Without a shared understanding of what you're proving, validation efforts can drift, and disagreements often emerge late in the project.

Approach

Once the claims are defined, decide how you’re going to prove them. That includes selecting the right test methods, identifying appropriate sample sizes, and applying the level of rigor that matches the risk. The approach should be practical, justified, and agreed upon before execution begins.

Gathering Evidence

This is where plans become action. Collect data, follow protocols, and ensure that every detail is documented. Context matters. So does consistency. This phase builds the factual record that supports your validation effort.

Summary

Finally, put it all together in a clear, logical, and audit-ready format. The summary should tell the story of what was done, why it was done that way, and how the results support your original claims. Auditors aren’t there to read minds, they’re there to read files. Make it easy for them to follow your thinking.

Today, CAGES® forms the foundation of two core services at Brayearst:

✅ Validation Training

We help teams understand not just the steps of validation, but how to think critically about risk, alignment, and documentation. Training programs are tailored for newcomers, cross-functional stakeholders, or teams looking to strengthen consistency across projects.

✅ Spot Check Reviews

Already have protocols or reports in place? Our structured assessments use the CAGES® lens to evaluate documentation for clarity, completeness, and audit readiness. It’s an efficient way to get expert feedback without overhauling your entire system.

Whether you're designing a new process, preparing for inspection, or trying to reduce rework, CAGES® offers a structure to support your success.

And it just might keep the bird from causing trouble.

If you'd like help applying the CAGES® Framework to your team’s validation process, I’d be glad to talk.

Validation has a reputation problem. Too often, it’s seen as the “bad guy” that shows up at the end of a project just to slow things down. But in many cases, the problem isn’t validation itself; it’s how late it enters the picture.

Imagine building out a new system or piece of equipment. The design is done. The installation is done. Everything is finally powered up and ready to go. Then, validation gets called in, and the first question is, “Why isn’t it already validated?”

When you’re brought in late, it’s hard to succeed. Validation isn’t meant to be a last-minute checklist; it’s a safeguard that protects your product, your process, and your timeline. It’s the part that confirms the system can do what you expect it to (consistently and safely).

At Brayearst, we use the CAGES® Framework to make validation easier and more effective. Through Validation Training and Spot Check Reviews, we help teams bring validation into the project plan early, so that it supports the team instead of becoming a blocker.

Planning early is what transforms validation from villain to partner.

Ready to change how your team thinks about timing?

Schedule time at meet.brayearst.com and bring validation into your process before it becomes a problem.

Validation can often feel like just another compliance task. Fill out the forms. Check the boxes. Submit the documents. But beneath the paperwork is something much more important: true process understanding.

When I first entered the life sciences field, I brought with me a chemical engineering background. Unlike some engineering disciplines that focus on designing objects, chemical engineering trains you to design processes. You learn to think about how materials move, change, and stabilize through every step of production. That same thinking applies directly to validation.

Many organizations approach validation by focusing on the product: What is it? What does it do? But effective validation also asks: How is it made? Where are the risks? Which steps introduce variation? Which controls truly matter?

Without strong process knowledge, companies may either over-validate or overlook hidden risks. They might test the wrong things, apply the wrong level of scrutiny, or struggle to justify their validation plans to regulators.

At Brayearst, this is why process-focused thinking is central to our approach. The fully registered CAGES® Framework helps teams build clear validation strategies that combine product knowledge with process expertise. Through Validation Training & Spot Check Reviews, we support organizations in building audit-ready, risk-justified validation documentation that grows with their manufacturing needs.

Validation isn’t just about paperwork. It's a profession — and process thinking belongs at its core.

But as I went through audit after audit, sometimes two in a single month, I started to notice something important. Even though the end products were labeled differently, the validation expectations were nearly the same.

Why?

Because the process steps were the same:

Blending. Refining. Packaging. Labeling. Testing.

No matter what the label says—drug, device, or biologic—the work of validation happens in those process steps prior to sale. It does not matter if the product will be swallowed, injected, or used in a diagnostic kit. What matters is whether the process that made it was consistent, well-documented, and proven to be capable.

This is where many life sciences teams get stuck. They are told to follow industry-specific guidance but are not taught how to adapt those guidelines to their actual technology.

That is why I talk about validation as a process-focused discipline. It is how we build credibility, not just compliance. And for smaller teams especially, this mindset can make all the difference in scaling safely and sustainably.

Ready to rethink your approach?

Schedule time at meet.brayearst.com to talk about strategies that fit your process, not just your product.

When we talk about validation in life sciences, it’s easy to think of it as a single step: something you check off a list to move forward.

But in reality, validation comes in many forms — and each one plays a different role in protecting your products, your patients, and your process.

🔹 Process Validation proves that your manufacturing process can consistently make good products, not just once, but over time.

🔹 Cleaning Validation ensures that when you switch from making one product to another, no residue or contamination carries over.

🔹 Software Validation confirms that the tools and systems you rely on are capturing accurate, reliable data — essential for traceability and audits.

🔹 Test Method Validation makes sure that when you check your products, your tests can truly tell a good one from a bad one.

Each type of validation needs its own strategy, its own focus, and its own evidence.

Getting it right isn’t just about meeting regulations — it’s about building trust in everything you manufacture.

At Brayearst, we help companies bring the right level of rigor to each type of validation, supporting smarter growth and stronger compliance.

Ready to look at your validation strategy with fresh eyes?

We’d love to help. Don't let small validation gaps grow into major risks.

📅 Book a time today at meet.brayearst.com and build strength into every layer of your manufacturing process.

If you've ever taken medication, used a medical device, or even received a diagnostic test, you've already benefited from validation. It’s the behind-the-scenes process that makes sure those tools are consistently safe, effective, and trustworthy; not just once, but every time they’re made.

When a new product is developed, the FDA requires proof that it works. But once the product is ready to be mass produced, a different challenge appears: proving the manufacturing process is just as consistent and reliable. That’s where validation comes in.

Validation ensures the equipment used in large-scale production (mixers, packaging lines, sterilizers, even software) operates within tightly defined parameters. It asks: Can we trust the process to do its job, over and over again?

Different types of validation tackle different risks:

• Process validation confirms a system produces quality products.

• Cleaning validation prevents contamination between batches.

• Software validation checks that data is correct and traceable.

• Test method validation makes sure we’re testing reliably.

For smaller life science companies, getting this right can be the difference between moving forward or falling behind. That’s why validation isn’t just a checklist; it’s a foundation for trust, quality, and patient safety.

Clarity leads to confidence.

Unlike large pharmaceutical giants with decades of credibility and deep pockets, smaller companies don’t have the luxury of absorbing costly compliance mistakes. A single misstep during an FDA audit could result in delays, expensive rework, or, in the worst cases, shutting down entirely.

Through my work in validation, I’ve seen how larger companies leverage their history and established processes to navigate compliance challenges. When the FDA raises a concern, they can point to decades of production data and robust quality systems. Smaller companies, however, don’t have that track record to fall back on. They must demonstrate compliance from the start, proving that their processes are reliable, repeatable, and well-documented.

Without a strong validation strategy, even an innovative product might never reach the market. The cost of addressing compliance issues after the fact can be overwhelming—sometimes too much for a startup to recover from. That’s why small companies need to take validation seriously from day one.

In my conversation with the IP Café podcast, I discussed why startups and smaller manufacturers need to prioritize validation early. If you’re working in the life sciences space, the key takeaway is simple: you can’t afford to get validation wrong.

Some organizations have a clear idea of what they need to validate and how they want to approach it, while others may only know the product they want to manufacture but lack a structured validation plan. No matter where a company starts, the key is to align validation efforts with product claims, process settings, and regulatory requirements.

For companies at the beginning of their validation journey, the first step is to define the claims they are making about their process. This includes identifying the process parameters, determining how those parameters are documented, and ensuring they are clearly outlined before moving forward. Having a solid understanding of these elements upfront makes the later steps of validation much smoother.

Other companies may already have a defined validation strategy, including sample selection and testing methods. They may know exactly what they need to test to ensure compliance with regulatory standards. However, some organizations only focus on product testing for release and may not have a plan for validating the entire process. In these cases, guiding them through the qualification of a population of samples is essential to ensuring that the manufacturing process consistently produces a reliable product.

Regardless of the starting point, the goal of process validation is to provide documented evidence that a manufacturing process is capable of consistently producing a product that meets established specifications. By tailoring the approach to each company's specific needs, validation professionals can help ensure compliance, product quality, and overall manufacturing success.

If a company neglects validation, it often doesn’t take long before regulators take notice. The FDA maintains a database of warning letters and compliance actions, and when a company fails to meet validation requirements, their name can appear in these public records. In some cases, businesses that ignore validation find themselves disappearing from the market entirely.

I recently came across a company that had a presence in a life sciences database but little else. Curious, I searched for more information and discovered an FDA warning letter associated with them. While I can't say for certain that the two are linked, the situation is suspicious. Could their failure to validate have led to regulatory action that ultimately shuttered their operations? It’s a real possibility.

Warning Letters and Compliance Pitfalls

For companies that continue operations despite receiving an FDA warning letter, the road ahead can be challenging. Consider a recent case I reviewed involving the qualification of a cleaning machine. The company had chosen to validate it as part of their process validation rather than conducting a cleaning validation—a decision that ultimately did not align with FDA expectations. Since the machine was being used for residue removal rather than direct manufacturing, it should have undergone cleaning validation. Their misstep resulted in regulatory scrutiny and a requirement to redo the validation properly.

The Takeaway

Validation is not a one-time checkbox but an ongoing process that ensures compliance, product quality, and ultimately, patient safety. Misclassifying or neglecting validation efforts can lead to significant regulatory, financial, and reputational damage.

For companies in life sciences, the lesson is clear: Validate the right way, the first time. Whether it’s cleaning, process, or equipment validation, ensuring compliance from the outset is the best way to avoid the costly consequences of an FDA warning letter—or worse, business failure.

Don't wait until it's too late. The FDA won’t skip you, so let’s make sure your validation holds up. Schedule a consultation at meet.brayearst.com.

When it comes to analytical method validation, the "Four R's" are crucial concepts: repeatability, reproducibility, robustness, and ruggedness. Understanding these elements helps ensure consistent and reliable results, which is vital when developing and validating analytical methods.

Repeatability and reproducibility are the most commonly used aspects of validation, often discussed in Six Sigma practices as part of Gage R&R (Gage Repeatability and Reproducibility) analysis. Repeatability refers to how consistent results are when the same person uses the same method and equipment multiple times under the same conditions. Reproducibility, on the other hand, tests whether different people, using the same method and equipment, can still produce consistent results, isolating any human technique or judgment effects.

Robustness and ruggedness can be more confusing because different sources use different definitions. Robustness is typically understood as the ability of a method to remain unaffected by small, deliberate variations in parameters, such as changes in temperature or pH. Ruggedness, often overlapping with robustness, usually refers to how well a method performs under varying environmental conditions or different labs.

In an international setting, achieving alignment on these terms can be challenging. Our workgroup found it useful to adopt broader, flexible definitions for robustness and ruggedness, allowing each site to stay consistent with its reference standards while still ensuring method reliability across the entire business unit.

Incorporating all four R's into your validation strategy is key to ensuring the reliability and quality of your analytical methods. Whether dealing with variations in operators, equipment, or environments, a solid understanding of these principles helps maintain the integrity of your methods and outcomes.

The Baltimore Together Summit 2024 left me feeling inspired and optimistic about the future of life sciences in our city. I attended Morning Panel #2, titled "Build from Strength: Life Sciences in Baltimore," which highlighted how Baltimore is fostering growth in the life sciences sector through local companies, research institutions, and strategic investments. The discussion was led by Dr. Arti Santhanam, Executive Director of the Emerging Technology Centers, and featured prominent figures such as Dr. Elizabeth Clayborne, Dr. Deborah Hemingway, Jesse Christopher, and Dr. Matt Tremblay.

Dr. Elizabeth Clayborne, CEO of NasaClip, captured the audience's attention with her journey from improvising solutions in the ER to founding NasaClip, a medical device company now generating significant revenue with partnerships such as Disney Cruise Lines. As a woman of color, Dr. Clayborne shared her challenges raising over \$3.5 million and emphasized the importance of representation and community support—an aspect she found in Baltimore—to help overcome barriers that women and minority founders often face.

Dr. Deborah Hemingway of Ecphora Capital echoed this sense of empowerment as she described her firm's focus on investing in medtech and life sciences companies. She noted how Baltimore is uniquely positioned to grow due to the incredible talent pool and existing ecosystem support, mentioning that her firm recently surpassed \$10 million in assets under management. Dr. Hemingway also highlighted the importance of Maryland's biotechnology investment tax credit, which has been instrumental in attracting external investors to the state.

Jesse Christopher, CEO of Longeviti, brought a different but equally exciting perspective, detailing how his company grew from garage-scale beginnings to a significant player in the neurotechnology space. He noted that the unique concentration of institutions like Johns Hopkins and the University of Maryland make Baltimore an epicenter of neurosurgical and medical innovation—something Longeviti is leveraging to produce cranial implants that are both functional and revolutionary.

Dr. Matt Tremblay of Blackbird Laboratories, a newer company focused on creating breakthrough therapeutics, brought up the value of collaboration across industries and how Baltimore's ecosystem supports the entire lifecycle of medical product development—from innovation to scale. He spoke about the generous support his company received from investors such as the Bisciotti family and stressed the importance of ensuring that companies grow here instead of moving elsewhere.

Exploring Effective Sampling Techniques in Cleaning Validation: A Comprehensive Guide

In the life sciences industry, cleaning validation is an essential process to ensure that equipment is adequately cleaned between production cycles, thereby preventing cross-contamination. Regulatory bodies, such as the FDA, require proof that residues from previous products, cleaning agents, and microbial contaminants are effectively removed. A critical aspect of cleaning validation is the use of appropriate sampling techniques to verify cleanliness. Let’s explore the most effective methods and introduce a supplementary technique: indirect sampling by susceptible product manufacture.

1. Swab Sampling

Swab sampling is one of the most commonly used methods for assessing surface cleanliness in cleaning validation. In this technique, wetted swabs are applied to equipment surfaces over a predefined area to collect potential residues of interfering and/or difficult to remove components, active pharmaceutical ingredients (APIs), or other contaminants. The swabs are then analyzed to determine the level of residues left after cleaning.

This method is ideal for hard-to-clean but accessible areas, such as seams, joints, and droplet forming surfaces. Swab sampling provides direct data on residue levels and is widely accepted by regulatory agencies. However, it may not be feasible for internal surfaces of complex equipment, such as small pipes or enclosed areas.

2. Rinse Sampling

Rinse sampling is another widely accepted method, particularly useful for equipment with inaccessible internal surfaces, like tanks, pipes, and blenders. A known volume of solvent (often water or another approved liquid) is used to rinse the equipment, and the resulting solution is analyzed for residues.

Rinse sampling offers a comprehensive approach to detecting contaminants, especially cleaning agents, that might not be captured through swabbing. It allows for analysis of residues from larger surface areas, including those that are difficult to access, like the insides of tubes or tanks.

3. Biomarker Sampling

In specific cases, particularly for microbial contamination, biomarker sampling can be used. This technique involves the use of specific biomarkers or indicators to assess the effectiveness of the cleaning process in removing microbial contaminants. It is especially relevant in facilities where sterile or aseptic manufacturing is critical.

Biomarker sampling is typically used as a supplementary technique in conjunction with swab and rinse sampling, providing additional assurance that microbial residues are not present after cleaning.

4. Indirect Sampling by Susceptible Product Manufacture

While not a primary method, indirect sampling by susceptible product manufacture can be a useful supplementary technique, particularly in situations where certain equipment areas are challenging to access directly. This technique involves manufacturing a test product that is known to be sensitive to contaminants from previous processes.

In this method, a susceptible product is run through the equipment after cleaning, and its quality is analyzed to detect any contamination or residue carryover. If the product fails certain quality parameters (e.g., purity, microbial limits), it may indicate that the cleaning process was insufficient in removing residues from inaccessible areas.

This approach is not intended to replace traditional swab or rinse sampling but can provide additional data when direct sampling is limited or impractical. For example, when some areas of the equipment are too complex or small for swabbing or rinsing, running a susceptible product can give insight into the presence of residues. This method works well in highly regulated environments where extra precautions are needed to demonstrate cleanliness.

Why Use Multiple Sampling Techniques?

The combination of these sampling techniques allows for a more thorough and reliable validation process. Swab sampling provides direct data from critical surfaces, rinse sampling covers large internal areas, biomarker sampling gives assurance against microbial contamination, and indirect sampling by susceptible product manufacture fills in the gaps where direct sampling methods may be inadequate.

Using multiple sampling techniques together ensures a comprehensive evaluation of cleaning processes and offers robust evidence for regulatory compliance.

Conclusion

In cleaning validation, no single sampling technique can fully assess equipment cleanliness. By combining swab, rinse, biomarker sampling, and indirect sampling by susceptible product manufacture, manufacturers can ensure that their equipment is thoroughly cleaned and free from contamination. This multi-pronged approach provides the necessary assurance to meet regulatory standards and maintain product safety and quality.

With proper implementation of these techniques, companies can reduce the risk of cross-contamination, ensure regulatory compliance, and protect the integrity of their products in an increasingly demanding environment.

In the world of validation, particularly in Performance Qualification (PQ) and Process Performance Qualification (PPQ), the number three holds a special place. But why do we often see a minimum of three studies as the benchmark? The rationale extends beyond mere convention; it’s a blend of statistical reliability, regulatory expectations, and practical cost considerations that come together to shape this standard.

One insightful perspective comes from the notion that one occurrence is an incident, two might be a coincidence, but three establish a trend. This concept underscores the importance of replicability in validation—where a single study can be dismissed as an outlier and two may leave room for doubt, three studies begin to demonstrate consistent, reliable performance.

This thinking aligns closely with Six Sigma principles, where three standard deviations from the mean define control limits in a process. In both cases, the number three marks the threshold where variability starts to be understood, and predictability emerges. By utilizing three studies, we strike a balance: obtaining enough data to confidently demonstrate process control without incurring unnecessary costs that come with excessive testing.

The balance of data value and cost cannot be overstated. While more data points can refine understanding, there comes a point of diminishing returns. The three-study rule optimizes this balance, offering robust evidence of consistent performance while managing resource expenditure. This approach reflects our commitment to efficient, compliant validation practices that stand up to scrutiny—an ethos central to the work at Brayearst Validation Consulting.

Ultimately, the three-study approach isn’t just a regulatory checkbox; it’s a strategic decision rooted in sound statistical reasoning, regulatory wisdom, and practical considerations. It exemplifies how we can deliver quality validation without compromising on time, cost, or compliance.

Process validation is a crucial aspect of quality assurance in manufacturing, especially in the life sciences and medical device industries. It ensures that a process consistently produces a product meeting its predetermined specifications and quality attributes. This systematic approach is vital for maintaining product safety, effectiveness, and regulatory compliance.

Understanding Process Validation

Process validation involves several key stages:

1. Process Design: This is the initial phase where the process is defined based on knowledge gained through development and scale-up activities. The goal is to design a process that consistently produces products that meet quality requirements.

2. Process Qualification: In this phase, the process design is evaluated to determine if it can reproduce consistent quality. This involves:

   • Installation Qualification (IQ): Verifying that equipment and utilities are installed correctly.

   • Operation Qualification (OQ): Ensuring that the equipment and systems operate according to their full range of intended use.

   • Performance Qualification (PQ): Confirming that the process produces the expected outcomes under real-world conditions.

3. Continued Process Verification: This ongoing phase ensures that the process remains in a state of control during routine production. It involves regular monitoring and documentation to detect any deviations or trends that might affect product quality.

Why is Process Validation Important?

Process validation is not merely a regulatory requirement but also a critical component of quality management. Here are a few reasons why it is essential:

• Regulatory Compliance: Regulatory bodies such as the FDA require process validation to ensure that manufacturing processes are consistent and controlled. Non-compliance can lead to product recalls, fines, and loss of market approval.

• Quality Assurance: Validated processes ensure that every product meets quality standards, reducing the risk of defects and ensuring patient safety.

• Cost Efficiency: By identifying and controlling variables that affect product quality, companies can reduce waste, minimize rework, and improve overall efficiency.

Statistics and Insights

According to a recall trends report by the FDA, about 50% of product recalls in the pharmaceutical industry are due to failures in the manufacturing process. This highlights the critical role of process validation in preventing such costly and potentially harmful incidents.

While working through a cause-and-effect diagram, one often missed aspect is the operator technique. For example, a procedure might say “apply detergent” or “use sanitizer” as part of the operator's tasks. Other parts of the procedure would likely specify the exact materials to be used as detergent or sanitizer. It may also include details like a mixture ratio for dilution or a required hold time for effective surface contact. The specific amount of application may be left to operator judgment, influenced by which aspect of good manufacturing practice the operator prioritizes.

 In one scenario, you might have an operator like Mr. Spritzer who aims to minimize time and material costs, applying just enough for the task. In contrast, another operator like Ms. Deluge may prioritize cleaning or sanitization effectiveness, applying a bit more with a safety margin. Depending on business and product risks, either Mr. Spritzer's or Ms. Deluge's approach could be suitable. However, without clear procedural definitions, variability could arise. This variability might lead to business risks due to high material costs or compliance risks due to contamination carryover. Understanding the process thoroughly helps pinpoint areas where risks can be mitigated or where additional controls are necessary.
