Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chromatography workflows are organized without segregation and transitions, then workflow management is simpler, but user authorization and audit trail capabilities are insufficient leading to potential misuse
Solution Approach 1:
The workflow is divided into discrete steps with defined transitions between them. Each step represents a distinct chromatography analysis task (e.g., integration, identification, quantification) that can be individually authorized and tracked. This segmentation enables granular user authorization where different users can be assigned to specific steps, and creates natural audit trail boundaries at each transition point.
Solution Approach 2:
Transitions serve as intermediary elements between workflow steps, acting as control points that enforce authorization rules and generate audit trail entries. The transition mechanism mediates between steps by requiring proper authorization before allowing progression, thus providing the reliability needed for user authorization and auditing without requiring complete restructuring of the workflow organization.
2Productivity
If multiple chromatography steps are combined into a single step, then workflow structure is simpler, but data processing efficiency and task-specific analysis are reduced
Solution Approach 1:
The workflow explicitly segments chromatography data processing into distinct task-specific steps such as integration, identification, and quantification. Each step processes data in a specialized manner optimized for its specific analytical task, improving overall data processing efficiency by avoiding the generalization that would result from combining all steps into a single operation.
Solution Approach 2:
The workflow structure provides a universal framework that can accommodate multiple different chromatography analysis tasks through standardized step and transition elements. This multi-functionality allows the same workflow infrastructure to handle various chromatography techniques (LC-MS, GC-MS, HPLC) and analysis types without requiring separate specialized systems for each.
3Reliability
If workflow steps are not segregated with transitions, then implementation is easier, but user authorization control and audit trail maintenance are compromised
Solution Approach 1:
The workflow system automatically generates audit trail entries and enforces authorization rules at transition points without requiring manual intervention. The transitions themselves are self-sufficient control mechanisms that inherently provide authorization checking and auditing capabilities, making the system reliable for authorization control while keeping implementation straightforward through automated rather than manual processes.
4Ease of operation
If a unified data structure is not used for workflow steps, then data modeling is more flexible, but workflow management and visualization complexity increases
Solution Approach 1:
A unified data structure is used to represent all workflow steps and transitions, providing a consistent model that simplifies workflow management and visualization. This universal data structure can represent different types of chromatography steps (integration, identification, quantification) and transitions through a common framework, making the system easier to operate while maintaining manageable complexity through standardization rather than through multiple specialized data structures.

AI summary
Exemplary embodiments provide methods, mediums, and systems for building and executing a chromatography workflow. According to the techniques described herein, the steps of the workflow may be arranged into an order and separated by gates and/or transitions. The transitions may represent locations in the workflow where responsibility or stewardship of the data in the workflow passes from one user to a different user. The steps may be represented as pages, with at least some of the steps represented by multiple different pages representing different customization options for visualizations, a configuration of the step, etc. By selecting pages for the various steps and connecting at least some of the steps with transitions, a user can build a workflow very quickly and efficiently. The resulting workflow supports improved auditing, enforces access rights, and improves workflow visualization, among other advantages.
