Systemic Training Gap #5: Operational Excellence and Sustained Procedural Discipline

Our review of recent FDA Warning Letters issued to medical device and pharmaceutical manufacturers found that written procedures, training records, and completed corrective and preventive actions (CAPAs) do not by themselves establish that a process remains in control. Deficiencies in equipment maintenance, cleaning, laboratory controls, line clearance, aseptic behavior, production documentation, and material handling keep surfacing in these letters, even when procedures and training records are available, because a pharmaceutical quality system only works when an organization maintains operational excellence and sustained procedural discipline.

Our review surfaced five systemic training gaps, and this is Gap 5 in our FDA Warning Letter series examining those gaps. This piece focuses on operational excellence and sustained procedural discipline.

What Happens When Procedures Exist but Are Not Consistently Followed

Our review found that an FDA Warning Letter rarely names an isolated mistake. It signals that operating conditions within a facility allow regulatory failures to develop, reflecting a broader oversight weakness rather than a single person's errors.

Failing to consistently follow written procedures can lead to operational failures and consequences such as:

• Compromised product safety and quality
• Erosion of data integrity
• Heightened regulatory scrutiny, extensive remediation obligations, and potential enforcement action
• Product recalls
• Financial losses
• Reputational damage
• Operational inefficiencies

Operational and Procedural Failures in Action

On June 3, 2026, FDA issued BlephEx, LLC, a medical device manufacturer, a Warning Letter over operational failures that illustrates the same gap in another regulated industry. FDA reported that the firm's vice president of operations acknowledged that the company had not followed its written CAPA procedure and indicated that he had been unaware of the procedure until the inspection was preannounced. 

When handpieces began overheating and, in some cases, catching fire, the firm replaced the power chargers involved but never opened a formal investigation into why they had failed or confirmed the fix actually worked. More than 191 days after the inspection closed, the same corrective action still hadn't been verified.

In a separate case, FDA's Warning Letter to Alchymars ICM SM Private Limited (May 21, 2026) found that an active pharmaceutical ingredient manufacturer's own cleaning and preventive maintenance records described a set of equipment as in good condition, yet inspectors found cracked and deteriorating gaskets, rust-like residue on product-contact surfaces, and wet paint on equipment still in production. 

The firm later attributed the gap to insufficient inspection rigor, directly admitting that its paperwork didn't reflect what was happening on the floor. The firm also acknowledged it had no equipment life cycle management program at all, meaning nothing was in place to catch this kind of deterioration before an inspector did.

A third case shows what happens when the same deficiencies go unresolved for years. In its Warning Letter to CareFusion 213, LLC (April 30, 2026), FDA noted it had already cited the facility for inadequate investigations in 2016 and inadequate laboratory controls and facility upkeep in 2023. When inspectors returned, the same categories of problems persisted, and FDA stated plainly that this pattern reflected inadequate executive management oversight, not a series of unrelated incidents.

A fourth case shows how procedural discipline can erode over years even when corrective actions are documented. In its Warning Letter to Pharmathen International S.A. (May 27, 2026), FDA observed an operator blocking first air while removing a fallen vial and failing to discard the exposed vial afterward, a basic aseptic behavior lapse. The firm's own CAPA program had not been effective at reducing recurring sterility and media-fill failures tied to operator error over the preceding five years, and its smoke studies had never been designed to evaluate exactly this kind of intervention in the first place.

Pharmaceutical leaders must pursue operational excellence by linking training to the actual job to demonstrate that their employees are qualified, rather than relying on course certificates as proof.

What FDA Observations Continue to Reveal About Procedural Gaps

Our review found the following issues related to operational excellence and procedural discipline appearing repeatedly.

Unusable Procedures and Changing Competencies

An organization's procedures may fail to accurately reflect how employees perform work. If a written procedure is vague, fragmented, or challenging to use, individuals cannot use it properly at the point of execution. Unusable procedures force teams to fill in the gaps with inaccurate information or best guesses, which often deviate from intended requirements.

Changing competencies can also hinder procedural discipline and operational excellence. Even if an employee is initially qualified, they can make mistakes when equipment, processes, responsibilities, or potential risks change. Competency reassessment is essential to ensure employees maintain a solid understanding of their roles and responsibilities.

Insufficient Oversight and Systemic Failures

When employees gradually deviate from approved procedures without managers or supervisors noticing, unofficial methods may unintentionally become the standard way that everyone performs tasks. Team leaders must watch, guide, and interact with how teams complete work so that they can address deviations. This helps prevent employees from taking shortcuts or making subtle modifications that differ from written instructions.

Reactive vs. Preventive Approaches

Reactive approaches only address maintenance, cleaning, equipment life cycles, and contamination control issues after they cause complications, while preventive approaches help identify and mitigate potential failures before they can impact product quality.

A mature PQS uses risk assessments, preventive maintenance, and routine monitoring of critical parameters to identify deterioration before it affects product quality. A reactive approach addresses failures after they have already affected products, resulting in more Warning Letters and further inspections.

Navigating the Cycle That Perpetuates Nonconformance

These patterns reinforce each other within a single operation. Procedures that are hard to use invite workarounds. Workarounds that go undetected become the normal way work gets done, and once that happens, retraining or CAPA aimed at the original problem doesn't hold, because the underlying work system, not the individual, was the actual cause.

Our review also found that many organizations track this cycle too late. Deviations and rejected batches are lagging indicators. They confirm control was already lost. Watching for leading indicators instead, like declining results from direct task observations, increasing procedural workarounds, overdue maintenance, or recurring minor deviations, can reveal discipline eroding before a failure occurs.

The primary question is no longer, “Did the organization follow its procedures?”, but rather “Does this organization’s PQS consistently enable employees to make scientifically sound decisions that protect product quality and patient safety?”

Why Procedural Knowledge Alone Is Not Enough

Procedural knowledge is essential, but it's just a foundation. Employees also need the right environment, support, and skills to sustain operational excellence.

Beyond Knowledge Assessments

Employees can pass knowledge assessments, yet still perform inconsistently in the operating environment. The following conditions are necessary for competence and procedural discipline:

• Practice
• Observation
• Feedback
• Accessible procedures
• Suitable equipment
• Adequate staffing
• Realistic schedules
• Supervisor reinforcement

Repeated pharmaceutical retraining is a helpful tool, but it does not replace the tools and oversight necessary to improve performance.

The Importance of Demonstrated Skill in High-Risk Operations

Verifying that qualification worked matters as much as designing it well. A written test can confirm someone knows the steps for a line clearance or an aseptic intervention. It can't confirm they'll perform those steps correctly when the schedule is tight, or the equipment isn't behaving as expected. Simulations, direct observation, and structured walk-throughs of the actual task provide much stronger evidence, and the criteria for what counts as acceptable performance need to be set before the assessment starts, not decided afterward based on how it went.

A competency statement needs to describe something you can observe, not just a general capability. "Understands aseptic technique" is too broad to teach, coach, or evaluate. "Can perform a line clearance using the approved sequence and acceptance criteria" and "Can perform an aseptic intervention without obstructing first air or compromising exposed sterile surfaces" are specific enough to build training around and confirm in practice.

Qualification should replicate the decisions, conditions, interventions, and risks that personnel may encounter. Testing only an employee's recall of written instructions does not reveal their true capabilities on the job, so it's essential to evaluate their demonstrated skills in the following areas:

• Aseptic technique
• Environmental monitoring
• Complex sampling
• Cleaning
• Equipment setup
• Laboratory execution

How Organizations Can Strengthen Operational Excellence

Organizations can strengthen operational excellence through the following practices:

• Clear, well-written procedures: Involving experienced operators, engineers, subject-matter experts, and quality professionals in designing and writing procedures helps produce instructions that are clear, accurate, and easy to follow.
• Task-based qualification and direct observation: Task-based qualification and direct observation help ensure teams apply what they learn in training.
• Proactive monitoring and layered audits: Monitoring procedural adherence through routine quality oversight, supervisory presence, layered audits, and observation of work helps organizations periodically reassess critical tasks and implement structured coaching, especially after adverse trends, changes, significant deviations, or extended absences.
• Training data connected to performance indicators: Linking training data to CAPA effectiveness, maintenance history, complaints, environmental trends, deviations, and right-first-time performance can help identify emerging risks.
• Treat recurring execution failures as signals to examine the work system: Recurring execution failures are also a signal to examine elements of the work system, such as staffing, workload, process design, equipment, and management priorities.
