Chromatography Activity Map for Versioned Audit Trails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chromatography analysis workflows lack efficient methods to ensure compliance with regulatory requirements, especially in industries with stringent data integrity and regulatory standards, such as pharmaceuticals and biotechnology, where changes to analysis workflows can compromise data integrity and compliance.
Innovation Solution
Implementing a processing activity map that versioned and archived result sets upon trigger conditions, such as moving across step boundaries or changing settings, to maintain a historical record of changes and ensure compliance with regulatory standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If versioned archiving of result sets is implemented upon trigger conditions, then compliance with regulatory requirements and data integrity are improved, but system complexity and storage requirements increase
Solution Approach 1:
The system segments the result set management by creating versioned copies at specific trigger points during workflow execution. Each version captures the state at critical moments (stage transitions, parameter changes), dividing the continuous data stream into discrete, manageable versions that can be independently archived and audited.
Solution Approach 2:
The system performs preliminary archiving actions by creating versioned copies of result sets before workflow changes occur. When trigger conditions are detected (such as moving across step boundaries or changing settings), the current state is captured and archived in advance, ensuring compliance documentation is ready before regulatory-critical changes take effect.
2Productivity
If historical records of workflow changes are maintained, then auditing efficiency and regulatory reporting are improved, but storage requirements and data processing overhead increase
Solution Approach 1:
The system extracts only the essential compliance-critical information from the complete workflow data. Instead of archiving entire result sets indefinitely, it captures specific trigger conditions and associated state changes, extracting and storing only the portions of data necessary for regulatory auditing while discarding redundant information.
Solution Approach 2:
Different versions of the result set are maintained with different levels of detail based on their purpose. The system applies local quality by storing comprehensive data for active workflow versions while maintaining condensed, trigger-point snapshots for historical archived versions, optimizing storage efficiency while preserving audit capability.
3Reliability
If trigger conditions flag points for result set persistence, then compliance with regulatory standards is improved, but workflow flexibility and analysis speed may be reduced
Solution Approach 1:
The workflow system automatically monitors itself for trigger conditions and performs self-archiving operations without external intervention. The system service detects when trigger conditions are met (stage boundaries crossed, parameters changed) and autonomously creates versioned copies, eliminating the need for manual compliance documentation while maintaining workflow continuity.
Solution Approach 2:
The system implements feedback mechanisms where the workflow execution state continuously feeds into the trigger condition evaluation logic. When changes occur in the workflow (such as moving between stages or modifying parameters), this feedback triggers automatic versioning decisions, creating a closed-loop system that adapts archiving actions to actual workflow dynamics without slowing down the primary analysis path.

AI summary
Exemplary embodiments provide methods, mediums, and systems for creating a processing activity map for an analysis workflow in a chromatography experiment. A result set for the analysis workflow may be created and maintained throughout various stages of the analysis workflow. When certain trigger conditions are met, the in-use version of the result set may be persisted. For example, a read-only historical archive copy of the result set may be created, while the previous version of the result set is used in further stages of the analysis workflow. The trigger conditions may include a number of situations such as moving backwards in the workflow and making a change, moving across gated step boundaries in the analysis workflow, or receiving an instruction to clear the result set. The persistent, historical copies of the result set may be used to support auditing of a compliance-driven analysis process.
