The Hidden Cost of Manual Validation
The FDA's Case for Quality Findings
In 2011, FDA CDRH launched the Case for Quality initiative following an in-depth review of device quality data and feedback from stakeholders. The initiative revealed a troubling reality: traditional Computer System Validation (CSV) practices were creating more problems than they solved.
Critical Finding: The Case for Quality research discovered that 80% of deviations were due to tester or test script errors rather than actual system failures. This meant that the vast majority of validation deviationsāwith their associated investigations, delays, and resource consumptionāstemmed from the validation process itself, not from the systems being validated.
Root Cause Analysis: The FDA's investigation found that traditional CSV methodology had testers spending 80% of their time documenting the process, whereas only 20% of their time was actually used for testing. This inverted priority structure led to:
Exhausted validators making transcription errors
Test scripts containing typos and formatting mistakes
Documentation-focused activities crowding out actual critical thinking
Recreated vendor documentation without added value
False positives overwhelming the deviation system
Regulatory Response: These findings led to the formation of the FDA-Industry Computer Software Assurance (FICSA) team in 2015, a collaborative group that partnered with FDA to develop Computer Software Assurance (CSA) guidance. The goal: shift from document-heavy compliance to risk-based testing that focuses on patient safety and product quality.
Traditional Challenges
Paper-based and hybrid validation systems introduce multiple points of failure that contribute to the FDA's documented 80% errant deviation rate:
1. Inconsistent Evidence Interpretation
Different reviewers apply varying standards to the same evidence
Subjective judgment leads to both false positives and missed issues
Lack of standardized evaluation criteria across validation packages
2. Documentation Quality Variability
Handwritten test results introduce legibility issues
Temporal gaps between execution and documentation
Incomplete or ambiguous expected results specifications
Transcription errors when transferring data between systems
3. Human Cognitive Limitations
Reviewer fatigue during lengthy validation campaigns
Pattern recognition failures for subtle anomalies
Confirmation bias when reviewing repetitive test cases
Manual error rates increase with documentation burden
4. Process Inefficiencies
Manual transcription errors from paper to electronic systems
Time delays between test execution and review
Inconsistent deviation classification and routing
Test script errors and typos
The Errant Deviation Problem
The FDA's findings align with industry data suggesting that 30-50% of validation deviations opened during execution are ultimately closed as "no action required" or attributed to documentation errors rather than actual system failures. The FDA's 80% figure for tester/script errors represents the most severe manifestation of this problem.
Each errant deviation:
Consumes investigation time and resources
Delays validation package completion
Requires QA review, root cause analysis, and formal closure
Diverts resources from legitimate quality issues
Obscures actual quality signals in the noise of false positives
More concerning, the inverse also occurs: subtle evidence anomalies escape detection because they fall within reviewer's "close enough" mental thresholds, potentially allowing real issues to proceed undetected.
The Valkit.ai Solution Architecture
Four-Pillar Approach
Pillar 1: Complete Digital Transformation
Valkit.ai eliminates paper entirely, addressing the FDA's core finding about documentation-driven processes. The platform creates a unified digital environment where:
Test protocols are executed directly in the system
Evidence is captured digitally at the point of execution
Expected results are precisely defined with acceptable ranges
Timestamps and user attribution are automatic and immutable
No manual transcription introduces errors
This foundational digitization directly addresses the FDA's 80% tester error finding by eliminating the most common failure modes:
No handwriting interpretation errors
No transcription between media
No test script typos affecting execution
No documentation formatting issues
The approach also addresses ALCOA principles at the source:
Attributable: All actions linked to authenticated users via electronic signatures
Legible: Digital evidence is inherently readable, with no handwriting interpretation
Contemporaneous: System timestamps ensure temporal accuracy
Original: Primary records exist only in the validated system
Pillar 2: AI-Powered Evidence Analysis
The platform's AI engine performs intelligent analysis of test evidence through:
Multi-Modal Understanding
Image recognition for visual evidence (screenshots, photographs, instrument outputs)
Text extraction and natural language processing for document evidence
Structured data validation for numeric and tabular results
Pattern recognition across similar test cases
Sophisticated Matching Algorithms
Fuzzy matching that accommodates acceptable variations
Semantic understanding of expected vs. actual results
Context-aware evaluation based on test case risk classification (aligned with FICSA/CSA risk-based approach)
Historical pattern analysis for anomaly detection
Example Analysis Output:
Latest Analysis: 11/20/2025, 6:35:53 PM
Match Level: Low Match
Evidence Summary:
The evidence indicates a low water alarm, which does not meet
the expected output of sufficient water levels.
Key Findings:
- The water level indicator shows a low level
- A low water alarm is active
- The expected sufficient water level is not met
Recommendations:
Investigate the water supply system to ensure adequate water
levels are maintained and sensors are functioning correctly.
Analysis Details:
Files Analyzed: 1
Overall Assessment: Low
Strengths: The evidence clearly shows the current water level status
Areas for Improvement: Water level below expected; alarm contrary to expected output
Pillar 3: Master Data Management
A centralized data architecture ensures consistency:
Master Data Tags: Customized master data tags
Data Capture Tables: Library of data tables
Images: Images available across the platform
This eliminates the variability introduced when each validator interprets requirements differently or when expected results evolve without proper change control.
Pillar 4: Intelligent Automation
The platform automates routine validation activities, aligning with FDA's recommendation to leverage automated traceability, testing, and the electronic capture of work performed to document the results ISPE:
Automatic deviation detection and preliminary classification
Smart routing based on deviation type and severity

AccurateThis is where AI makes the most significant impact on the FDA's 80% tester error problem:
Traditional manual review operates on pattern matching within the reviewer's experience and is prone to the errors identified by the Case for Quality initiative. The AI system operates on:
Precise Specification Matching: Compares evidence against explicit, structured acceptance criteria without unconscious bias or transcription errors
Quantitative Analysis: Extracts numerical data from evidence and performs statistical validation against specified rangesāeliminating manual calculation errors
Visual Pattern Recognition: Detects subtle anomalies in graphical evidence that human reviewers might rationalize as acceptable
Consistency Checking: Cross-references current evidence against historical patterns to identify outliers
Elimination of Test Script Errors: No manual execution of test scripts means no typos, formatting issues, or copy-paste errors that generate false deviations
Complete (ALCOA+)
Validation of required evidence attachments before test case closure
Cross-referencing of traceability matrix to ensure coverage
Automated detection of missing data fields
Smart prompts for additional context when needed
Reducing Errant Deviations
Addressing the FDA's 80% Finding
1. Eliminating Transcription and Documentation Errors
The digital capture directly addresses the FDA's finding that 80% of deviations stem from tester or test script errors:
Traditional Process (Source of 80% of Deviations):
Tester captures screenshot
Prints screenshot
Handwrites notes on printout (potential for illegibility)
Attaches to validation package (potential for loss)
Reviewer interprets handwriting (potential for misinterpretation)
QA reviewer re-interprets during approval (additional interpretation layer)
Deviation opened due to unclear documentation or transcription error
Investigation reveals no actual system failureājust documentation issues
Valkit Process:
Tester captures evidence digitally
Evidence automatically attached to test case
AI performs immediate analysis
Clear pass/fail determination with reasoning
No interpretation required; no deviation unless legitimate
Eliminates the 80% of deviations attributable to documentation errors
2. Standardizing Acceptance Criteria
Master data management ensures that expected results are:
Precisely defined with quantitative ranges where applicable
Consistently applied across all executions of a test case
Version-controlled with formal change management
Risk-assessed using FICSA/CSA principles to determine appropriate tolerance levels
This eliminates situations where different reviewers have different mental models of "acceptable" resultsāa key contributor to the false positive problem.
3. Objective Evidence Evaluation
The AI system removes subjective judgment from routine evidence review, addressing another source of the FDA's documented deviation problem:
Example Scenario: System Response Time Validation
Traditional Review (Prone to Tester Error):
Expected: "System responds in acceptable time"
Tester documents: "3.2 sec" but writes unclearly as "3.5 sec"
Reality: Actual response was 3.2 seconds but documentation error creates confusion
Alternative: Tester makes calculation error documenting result
Result: Either false positive or false negative deviation
Valkit AI Review:
Expected: "System response time ā¤3.0 seconds"
Evidence: Screenshot showing 3.2 second response (captured digitally, no transcription)
AI analysis: Extracts timestamp data directly ā 3.2 seconds measured
Determination: "3.2 > 3.0 seconds; does not meet acceptance criteria"
Result: Legitimate deviation opened for investigation
No documentation errors, no tester errors, no transcription errors
Catching Subtle Nuances
Where AI Excels Beyond Human Capability
Visual Anomaly Detection
Example: Water Level Monitoring System
The example analysis demonstrates the system's ability to detect nuanced issues that might be overlooked in documentation-heavy processes where reviewers are fatigued:
The water level indicator shows a low level
A low water alarm is active
The expected sufficient water level is not met
A human reviewer focused on documentation compliance might rationalize: "Well, there's still some water in the tank, and the system is showing readings, so it's basically working." The AI recognizes that the presence of a low water alarm is definitionally inconsistent with "sufficient water levels" as specified in the acceptance criteria.
Pattern Recognition Across Test Cases
The AI maintains context across an entire validation package:
Detects when multiple test cases show marginal passes near specification limits
Identifies trending degradation in performance metrics
Recognizes inconsistent behavior across related functional areas
Flags when evidence format changes unexpectedly (possible system modification)
Quantitative Precision
Human reviewers often apply "good enough" thresholds unconsciously, especially when fatigued by documentation tasks. The AI enforces exact specifications:
Temperature must be 20Ā°C Ā± 2Ā°C ā 22.1Ā°C is a clear fail, not "close enough"
pH between 6.8-7.2 ā 7.25 is outside specification, regardless of how "close" it seems
99.9% uptime required ā 99.87% is non-conforming, even though it's "almost there"
Contextual Understanding
Advanced natural language processing enables the AI to understand relationships:
Expected Result: "System shall display error message and prevent data entry when required field is blank"
Evidence Provided: Screenshot showing error message "Field cannot be empty"
AI Analysis:
ā Error message displayed
ā Data entry prevented (confirmed by lack of save action in evidence)
ā Message content appropriate to situation
ā PASS with confidence
No Test Script Typos
Unlike manual test scripts that can contain errors, the AI evaluates against structured, version-controlled acceptance criteria stored in the master data repositoryāeliminating another source of the FDA's 80% tester error finding.
Master Data Management: The Foundation
Ensuring Consistency at Scale
Test Case Library Management
Valkit.ai encourages the creation of centralized libraries of standardized validation packages aligned with "least-burdensome" principles:
When this test case is used across multiple validation packages (system install, upgrade, patch), the same precise criteria apply every timeāeliminating documentation variability that contributes to errant deviations.
Version Control and Change Management
When specifications change, the platform enforces controlled updates:
Change request initiated through digital workflow
Impact analysis performed (which validation packages use this test case?)
Risk assessment updated using CSA methodology
Change approved by appropriate stakeholders
New version created with audit trail
Historical test results retain original acceptance criteria
Future executions use updated criteria
This prevents the common scenario where different validators use different versions of specifications, leading to inconsistent pass/fail determinationsāanother contributor to the false deviation problem.
Risk-Based Classification
Integration with Valkit.ai's Product Risk Management and alignment with FICSA/CSA principles ensures that:
High-risk test cases (direct patient safety impact) receive more stringent evaluation
Medium-risk test cases (indirect impact) use appropriate tolerance levels
Low-risk test cases (no patient safety impact) allow for streamlined review
The AI adjusts its strictness based on risk classificationāa subtle deviation in a high-risk custom calculation receives different treatment than the same degree of variation in a low-risk user interface label. This risk-based approach aligns with the FDA's CSA guidance recommendation to determine the level of assurance effort and activities appropriate to establish confidence in the software ISPE based on patient safety impact.
Regulatory Alignment

Conclusion
The convergence of digital transformation, artificial intelligence, automation, and master data management creates a validation paradigm shift that directly addresses the FDA's documented finding that 80% of validation deviations stem from tester and test script errors rather than actual system failures.
Valkit.ai demonstrates that technology can simultaneously:
Eliminate the 80% problem by removing manual documentation, transcription, and test script execution from the validation process
Reduce false positives by eliminating subjective interpretation and human cognitive limitations
Improve sensitivity by detecting subtle anomalies beyond human perceptual capabilities, especially when reviewers are fatigued by documentation tasks
Strengthen data integrity through native digital implementation of ALCOA+ principles
Accelerate cycle times by automating routine review activities and eliminating investigation of documentation-related deviations
Enhance compliance by maintaining consistent, auditable processes aligned with FDA FICSA/CSA principles
Support regulatory evolution by implementing the risk-based approach recommended in Computer Software Assurance guidance
The traditional trade-off between validation speed and quality is resolved. Organizations implementing this approach achieve faster validation cycles while simultaneously improving the quality and reliability of their validation evidence.
The FDA's Case for Quality initiative revealed the fundamental problem: validation processes were generating more errors than the systems they were validating. By addressing the root causes identified by FDA CDRHādocumentation burden, tester errors, test script mistakesāValkit.ai enables validation teams to focus on what matters: ensuring systems perform reliably and safely.
Most importantly, validation teams can redirect their expertise from administrative evidence review and deviation investigations of documentation errors to higher-value activities: designing better test strategies, investigating root causes of real issues, and continuously improving validation approaches based on data-driven insights.
The future of validation is not paper versus digital, or human versus AI. It is the intelligent combination of digital systems, artificial intelligence, and human expertiseāeach applied where it provides maximum valueāworking together to eliminate the 80% of deviations that should never have occurred in the first place.
