The Hidden Cost of Rebuilding GMP Decisions

The most expensive quality-system problem is often not the original deviation. It is what happens when the organization must reconstruct the reasoning behind a decision it already made.

Executive Summary

Quality systems reliably preserve what was decided—the disposition, signature, and closure. They do not always preserve why that decision was authorized. FDA enforcement records show what happens when organizations must revisit historical investigations and reconstruct the evidence, context, and reasoning behind prior decisions.

Executive Summary

  • Quality systems reliably preserve what was decided — the disposition, signature, and closure. They do not reliably preserve why that decision was authorized.
  • FDA enforcement actions increasingly require organizations to conduct retrospective reviews of historical decisions — at Sanofi, Sun Pharma, RemedyRepack, Natco, and ABBE Laboratories — because the reasoning behind those decisions was not durably captured at the time.
  • When reasoning is not preserved, organizations pay a recurring cost to rebuild it: the Reconstruction Tax — senior labor, operational delay, knowledge loss, and repeated work.
  • A closed workflow is not proof of decision defensibility. Approval is not explanation. Signature is not reasoning.
  • The only two moments to establish the reasoning behind a decision are when it is made, or after someone challenges it. The first is preservation. The second is reconstruction.
  • ComplianceWorxs exists to capture, pressure-test, and preserve that reasoning while it is still available — before it must be rebuilt under pressure.

Preserve reasoning when the decision is made, and measure your own exposure

The formal quality record and the reasoning behind the record are not necessarily the same thing.

A deviation can be closed. A CAPA can be approved. A batch can be released. An investigation can have signatures, dates, attachments, and an approved disposition.

Yet when that decision is challenged later — during an FDA inspection, repeat investigation, technology transfer, customer audit, leadership transition, litigation, or another escalation — the organization may discover that the outcome survived but much of the decision context did not.

Then the work begins again. Teams retrieve records, search email, compare versions, interview subject-matter experts, and attempt to reconstruct what was known and why an action was justified at the time.

That is the Reconstruction Tax. And FDA enforcement records show it is not a theoretical problem.

Your QMS records what was decided.
ComplianceWorxs preserves why it was authorized.

FDA Is Already Forcing Retrospective Reconstruction

Consider what FDA required of Sanofi following an inspection of its manufacturing facility in Toronto.

Regulatory Case — Sanofi, Warning Letter, January 2025

FDA did not simply ask Sanofi to correct a procedure going forward. The agency called for an independent retrospective review of investigations involving unexplained discrepancies and batch or component failures for applicable U.S. products.

For each historical investigation, FDA expected the review to determine whether the investigation had been thorough, whether investigative activities had been adequately described, whether root causes had been identified, whether CAPAs were scientifically justified, and whether appropriate methods had been established to determine CAPA effectiveness.

For inconclusive OOS investigations, FDA went further — calling for review of production records, manufacturing steps, equipment and facilities, raw-material variability, process capability, deviation history, complaint history, and batch-failure history.

Source: FDA Warning Letter, Sanofi — 690604

Think about what that means operationally. The organization is no longer merely managing the original quality event. It is being required to go backward through historical decisions and establish whether the evidence, investigation, reasoning, conclusions, and resulting actions were adequately supported. That is reconstruction.

Sanofi is not an isolated example.

Regulatory Case — Sun Pharmaceutical Industries, Warning Letter, June 2024

FDA criticized the company’s OOS investigations for insufficient rigor and scope in determining root causes and evaluating the extent and product impact of deviations.

FDA required an independent retrospective review of three years of invalidated OOS results for U.S. products, including examination of the scientific justification and evidence supporting those historical decisions.

Source: FDA Warning Letter, Sun Pharmaceutical Industries — 677337

Three years. The operational issue is no longer one failed test or one investigation. The organization must revisit a portfolio of historical decisions and determine whether the reasoning supporting those decisions remains defensible.

The longer the interval between the original decision and that retrospective examination, the harder the problem becomes. Personnel change. Memories fade. Systems change. Documents move. Context disappears.

What Reconstruction Actually Looks Like

When historical reasoning is not readily available, organizations generally have to assemble it from whatever remains:

  • Pulling batch records, executed forms, laboratory data, deviation files, CAPAs, SOPs, training records, change controls, equipment logs, manufacturing records, and complaint histories.
  • Searching email, Teams or Slack messages, network drives, spreadsheets, and personal files for context that never became part of the durable decision record.
  • Interviewing subject-matter experts, Quality, Manufacturing, laboratory staff, engineering, managers, and sometimes former employees to establish what occurred.
  • Rebuilding timelines manually: what was known on each date, who reviewed the information, when the risk assessment changed, and why one action was selected instead of another.
  • Reconstructing the scientific basis for conclusions that appear in the formal record but whose supporting reasoning is no longer obvious.
  • Creating new chronologies, summaries, and response packages for auditors, investigators, customers, legal counsel, executive leadership, and regulators.
Exhibit 3The Reconstruction Loop
SearchInterviewReconcileReconstructExplain

This loop repeats every time a historical decision is challenged — by an inspector, a customer, a new Quality leader, or counsel — because none of its five steps existed as part of the original decision record.

This is not hypothetical administrative busywork. FDA Warning Letters provide unusually clear examples.

Regulatory Case — RemedyRepack, Warning Letter, May 2023

The company experienced multiple deviations involving broken tablets caused by packaging equipment. The deviations were handled as individual occurrences rather than as a broader pattern.

According to FDA, investigations concluded that no further action was necessary — but did not explain why that conclusion was justified. FDA also found inadequate root-cause determination and CAPA.

Source: FDA Warning Letter, RemedyRepack — 649198

That distinction is critical. The problem was not simply that an investigation record existed or did not exist. A conclusion existed. What FDA challenged was the basis for the conclusion.

A Record of the Conclusion Is Not Necessarily a Record of the Reasoning

Regulatory Case — Natco Pharma, Warning Letter, April 2024

An investigation involved missing batch-record pages in which critical manufacturing steps were recorded 25 days after production. The company concluded that operator inattention was the most probable cause.

In another case involving missing sample-weight balance printouts, the sample weight was changed 22 days after the analysis, and analyst error was identified as the most probable cause.

FDA’s concern was not that information had been entered late. The agency stated that the investigations had been concluded without root-cause determinations supported by evidence and without appropriate CAPA.

Source: FDA Warning Letter, Natco Pharma — 672564

This gets to the center of the problem. A quality system can contain: Decision: Operator error. Decision: Analyst error. Decision: No further action necessary. Decision: Batch acceptable. Decision: CAPA effective.

But an investigator, auditor, new Quality leader, customer, or executive may reasonably ask: Why? What evidence excluded other explanations? What alternatives were considered? What risk did the organization accept? Who had authority to accept that risk? What made the conclusion reasonable at the time the decision was made?

Those questions require something more than the disposition field. They require the record behind the decision.

Why the Reconstruction Tax Becomes Expensive

The original deviation may have been isolated, correctable, and operationally manageable. But if the reasoning supporting the response is scattered across disconnected systems and individual memory, the effort required to reconstruct it can become disproportionate to the original event.

Exhibit 4Where the Reconstruction Tax Accumulates

Senior Labor

Operational Delay

Knowledge Loss

Repeated Work

Four components of the same underlying cost — the same historical decision is often reconstructed more than once, by the most expensive people in the organization.

Senior labor

Reconstruction is rarely delegated to low-cost administrative resources. It often requires the same people whose judgment mattered originally — Quality leaders, Manufacturing leaders, laboratory management, engineering, validation, regulatory, technical operations, and site leadership. The organization consumes expensive judgment to recreate historical judgment.

Operational delay

Every hour spent explaining an old decision is an hour not spent addressing a current one. Investigations wait. Improvement projects wait. Technology transfers slow. Inspection preparation expands.

Knowledge loss

A technically sophisticated decision may have been entirely reasonable when made. But if the reasoning existed primarily in conversations, email, or the minds of experienced employees, staff turnover can transform a known decision into an organizational mystery.

Repeated work

The same historical decision may be reconstructed more than once — for an internal investigation, again for a customer, again during technology transfer, again during an inspection, again after leadership changes. The intellectual work was performed when the decision was made, but the organization keeps paying to reproduce it.

FDA’s Own Expectations Make the Distinction Important

FDA’s Quality Risk Management guidance provides useful context. ICH Q9(R1), adopted by FDA, specifically addresses weaknesses involving risk-based decision-making, including lack of clarity around risk-based decisions, insufficient understanding of appropriate formality in Quality Risk Management, and subjectivity in risk assessments and QRM outputs.

Quality decisions are not simply clerical events. Evidence must be interpreted. Risk must be evaluated. Uncertainty must be managed. Someone must ultimately determine whether the available evidence is sufficient to authorize an action. The formal workflow records the resulting action — but the organization’s ability to defend that action later depends on whether the underlying reasoning remains intelligible.

Regulatory Case — ABBE Laboratories, Warning Letter, 2025

FDA stated that complete and accurate batch production and control records are necessary for consistent and reproducible manufacturing, and that incomplete manufacturing records can impair reliable batch-record review and adequate investigation of deviations and batch failures. FDA required a broad assessment of documentation systems and remediation of documentation practices.

Source: FDA Warning Letter, ABBE Laboratories — 708309

Again, the issue extends beyond whether documents technically exist. The organization must be able to use the record to understand what occurred and evaluate the decisions associated with it.

The Problem Is Often Not Too Little Information

This is one of the paradoxes of modern Quality systems. Many organizations do not suffer from an absence of information. They suffer from an abundance of disconnected information.

The batch record may be in the eQMS. The laboratory result may be in LIMS. Equipment information may be in another system. The risk assessment may be a spreadsheet. A technical discussion may exist in Teams. An important qualification may be buried in email. Meeting notes may explain why one alternative was rejected.

Each system may be functioning exactly as designed. Yet the intellectual chain connecting Evidence → Alternatives → Risk → Reasoning → Decision → Authorization may not exist anywhere as one durable record. That is an architectural problem. The organization has preserved the pieces but not necessarily the reasoning connecting them.

A Closed Workflow Can Create False Confidence

A completed workflow does not automatically prove that reasoning has been preserved, but neither does missing reasoning automatically establish regulatory noncompliance. Those are different questions.

The more precise distinction is between workflow completion and decision defensibility.

A conventional QMS is very good at establishing whether the deviation was opened, the investigation completed, the CAPA approved, the disposition authorized, and the workflow closed.

Decision defensibility asks a different set of questions: what evidence was available, what evidence mattered, what alternatives were considered, how risk was evaluated, why this course of action was selected, and whether someone who was not present could reconstruct that reasoning from the record itself.

The first set establishes workflow control. The second preserves institutional judgment. They are not the same thing.

When the Conclusion Survives but the Supporting Reasoning Does Not

The RemedyRepack example illustrates this well. The company had investigations. Quality personnel had signed them. Conclusions had been reached. FDA nevertheless criticized the investigations because similar deviations had been treated individually, root causes had not been adequately established, and conclusions lacked explanation.

Approval is not explanation. Signature is not reasoning. Closure is not defensibility. And a disposition is not necessarily a durable record of why the disposition was authorized. The distinction becomes visible only when someone challenges the decision. By then, preserving the reasoning is no longer possible — the only remaining option is reconstruction.

The Economic Cost of Reconstruction

There is no credible universal industry benchmark that tells a manufacturer exactly what its Reconstruction Tax should be. That is why ComplianceWorxs does not assign one. Instead, the burden can be calculated using the organization’s own experience.

Exhibit 5 — Illustrative Example, Not an Industry Benchmark

Suppose an organization experiences 24 situations each year in which an important historical GMP decision has to be materially reconstructed — arising from repeat investigations, OOS inquiries, customer audits, technology transfers, inspection preparation, leadership questions, complaints, personnel departures, supplier issues, or recurring deviations.

Assume five experienced employees become involved in each reconstruction, and each spends an average of 15 hours locating information, reviewing evidence, attending meetings, rebuilding chronology, reconciling records, and preparing explanations.

The arithmetic is simple: 24 reconstruction events × 5 people × 15 hours = 1,800 senior labor hours per year.

That is not a claim about what every pharmaceutical company experiences. It is a method for making an otherwise invisible operating burden visible — and it excludes delays to current investigations, management interruption, opportunity cost, external consultants, legal review, and repeat work.

This is why organizations should calculate their own burden rather than rely on generic industry averages.

At Enterprise Scale, Remediation Can Become Financially Material

It is important not to confuse the Reconstruction Tax with the total cost of regulatory remediation. They are not the same thing. But large enforcement situations demonstrate how financially consequential quality-system remediation can become once problems escalate beyond ordinary operations.

Enterprise Example — Philips / Respironics Consent Decree

Philips disclosed a €363 million provision associated with remediation activities, inventory write-downs, and contractual provisions related to the Respironics consent decree, and expected further remediation and related costs during 2024.

Source: The Wall Street Journal

That figure should not be presented as the cost of decision reconstruction — it isn’t. It demonstrates something narrower: once quality-system problems become enterprise remediation programs, the economic consequences can become material enough to affect corporate financial reporting.

The Reconstruction Tax exists earlier and more quietly. It accumulates in Quality budgets, senior labor, investigation duration, inspection preparation, and repeated attempts to explain historical decisions. Because those costs are distributed, companies may never aggregate them — that does not mean they are insignificant. It means they are hidden.

The Most Revealing Question

For Quality and executive leaders, a better question than “How many deviations did we close?” is this:

If an inspector, investigator, customer, new Quality leader, or board member asks us six months from now why we authorized this decision — can we explain it quickly, credibly, and from the record?

Not: Can the SME remember? Not: Can we search Outlook? Not: Can we schedule three meetings with Manufacturing and Quality?

The question is whether the organization preserved enough contemporaneous context that the reasoning can be understood without recreating it under pressure. If the answer depends on inbox searches, spreadsheet reconciliation, interviews, and institutional memory, reconstruction exposure already exists.

Exhibit 6Preservation vs. Reconstruction

At Decision Time

  • Evidence is available
  • Alternatives are known
  • The decision-maker is present
  • Cost to document: low

Six Months Later

  • Context has decayed
  • Personnel may have changed
  • Systems and records are disconnected
  • Cost to explain: high, and rising

What ComplianceWorxs Is Designed Around

The operating implication is straightforward.

If decision reasoning becomes expensive to reconstruct after the fact, the lower-cost intervention is to preserve it when the decision is made.

That is the problem ComplianceWorxs is designed to address.

Your QMS records what was decided.
ComplianceWorxs preserves why it was authorized.

The Record Behind the Decision preserves the evidence considered, alternatives evaluated, risk judgment, decision reasoning, and authorization while that context is still available. It complements the QMS rather than replacing it: the QMS governs the workflow; the decision record preserves the reasoning behind the authorized outcome.

The objective is not more documentation for its own sake. It is not replacing the QMS. It is not determining whether a customer is compliant. It is not making Quality decisions for the organization.

The objective is narrower: preserve the evidence, alternatives considered, risk judgment, decision reasoning, and authorization while that context still exists — because there are only two times to establish the reasoning behind an important decision. The first is when the decision is being made. The second is after someone challenges it. The first is preservation. The second is reconstruction.

Measure Your Own Reconstruction Tax

The first step is not buying more software. It is determining whether the problem exists in your organization and, if so, where it is concentrated. The Decision Defensibility Assessment examines three dimensions independently:

  • Decision Defensibility Posture — whether reasoning behind critical GMP decisions is consistently preserved with the decision record.
  • Reconstruction Burden — the organizational effort consumed when historical decision context must be rebuilt from disconnected records and institutional knowledge.
  • Operational Risk Concentration — the GMP decision types and process areas where reconstruction exposure is concentrated.

It does not produce a composite compliance score. It does not make a regulatory determination. It does not benchmark your organization against fabricated industry averages. The quantitative portion begins blank — you provide the numbers.

Can your organization explain why a critical GMP decision was authorized — without reconstructing it?
