MES System – Detailed User Functions, Use Cases, and Dialog Specifications

This section provides a detailed breakdown of user functions, use cases, and required dialogs for the MES modules:

  1. Master Batch Record (MBR) Management
  2. Recipe Design & Workflow
  3. Process Instructions & Operator Execution
  4. Electronic Batch Record (EBR) Execution

1. Master Batch Record (MBR) Management

1.1. User Functions

Role Function
Process Engineer Create, edit, and approve MBRs
QA Manager Review and release MBRs
Operator View MBRs during execution

1.2. Use Cases

Use Case Description
UC-MBR-001: Create MBR Define batch structure, materials, and process steps.
UC-MBR-002: Approve MBR QA reviews and approves with e-signature.
UC-MBR-003: Version Control Track changes and roll back if needed.
UC-MBR-004: Link to BOM Associate materials with batch steps.

1.3. Dialogs & Functionalities

Dialog Functionality
MBR Editor Drag-and-drop process steps, define parameters, set dependencies.
MBR Approval Digital sign-off with reason for approval/rejection.
MBR Version History Compare versions, restore previous MBRs.
BOM Linker Assign materials to process steps (auto-validate against ERP).

2. Recipe Design & Workflow

2.1. User Functions

Role Function
Process Engineer Design and configure recipes.
Production Supervisor Adjust parameters for a batch.
Operator Execute recipe steps.

2.2. Use Cases

Use Case Description
UC-REC-001: Create Recipe Define phases, parameters, and equipment.
UC-REC-002: Scale Recipe Adjust batch size (automatically recalculate quantities).
UC-REC-003: Conditional Logic Set rules (e.g., "If temperature > X, extend mixing time").
UC-REC-004: Recipe Simulation Test workflow before execution.

2.3. Dialogs & Functionalities

Dialog Functionality
Recipe Builder Visual workflow editor (phases, transitions, parameters).
Parameter Configurator Set min/max values, formulas, units.
Recipe Simulator Dry-run execution to validate logic.
Equipment Assignment Link steps to specific machines (with availability checks).

3. Process Instructions & Operator Execution

3.1. User Functions

Role Function
Operator Follow guided instructions, input data.
Supervisor Monitor progress, intervene if deviations occur.
Maintenance Respond to equipment alerts.

3.2. Use Cases

Use Case Description
UC-OP-001: Guided Execution Step-by-step instructions with mandatory checks.
UC-OP-002: Data Entry Manual input (e.g., pH readings) with validation.
UC-OP-003: Deviation Handling Record exceptions and trigger alerts.
UC-OP-004: Multimedia Support View images/videos for complex steps.

3.3. Dialogs & Functionalities

Dialog Functionality
Operator HMI Touch-friendly interface with progress tracking.
Data Entry Form Structured input fields (numeric, dropdown, barcode scan).
Deviation Log Record issues, attach photos, assign corrective actions.
Real-Time Alerts Pop-up notifications for critical deviations.

4. Electronic Batch Record (EBR) Execution

4.1. User Functions

Role Function
Operator Execute and record batch steps.
QA Reviewer Verify compliance before release.
Auditor Trace historical batch data.

4.2. Use Cases

Use Case Description
UC-EBR-001: Batch Initiation Start a new batch from an approved MBR.
UC-EBR-002: Automated Data Capture Pull sensor/PLC data into EBR.
UC-EBR-003: Batch Review QA checks completeness before approval.
UC-EBR-004: Batch Report Export Generate PDF/Excel for compliance.

4.3. Dialogs & Functionalities

Dialog Functionality
Batch Dashboard Overview of active batches, status, alerts.
EBR Viewer Timeline of executed steps with data.
QA Review Panel Approve/reject with comments and e-signature.
Batch Report Generator Customizable templates (PDF, CSV).

5. Integration & Compliance Dialogs

Dialog Functionality
Audit Trail Viewer Track all changes (who, when, what).
Electronic Signature Role-based sign-off (FDA 21 CFR Part 11 compliant).
ERP/LIMS Sync Real-time material & QC data exchange.

6. Summary of Key UI/UX Requirements

  • Role-Based Dashboards: Different views for operators, engineers, QA.
  • Minimal Clicks: Guided workflows reduce errors.
  • Real-Time Validation: Auto-check inputs (e.g., "Weight must be 50-100g").
  • Offline Mode: Continue execution if network fails (sync later).

7. Next Steps

  1. Prototype UI/UX for operator and engineer screens.
  2. Conduct User Testing with real operators.
  3. Validate Compliance against GxP regulations.

This specification ensures the MES system is user-friendly, compliant, and efficient for batch manufacturing. Adjust based on industry-specific needs (Pharma, Food, Chemicals).
