Collaborative Design Feedback for the Diagnostic Digital Thread

The Redline Module brings true multi‑stakeholder collaboration to diagnostic engineering. Built on the expanded eXpressML comment architecture introduced in eXpress 8.2, it allows anyone using either the eXpress Design Viewer or DSI Workbench to create structured comments tied directly to elements within an eXpress design. These comments flow seamlessly back into eXpress, where engineers can review them, navigate instantly to the referenced model element, compare proposed changes, and—when supported—apply suggested updates automatically.

Because they are stored in eXpressML—DSI’s open, extensible modeling language for Diagnostic Engineering (and beyond)—comments produced by the Redline Module can be parsed into software applications other than eXpress. Moreover, any tool capable of writing to eXpressML can produce comments that can be reviewed in eXpress or added to the digital archive.

The Redline Module transforms design feedback into part of the authoritative digital thread. Comments can be embedded within the eXpressML model itself, creating enduring, traceable annotations that support audits, sustainment planning, and long‑term model governance.

Key Features

• Stakeholder-generated comments from the eXpress Design Viewer or DSI Workbench
• Direct navigation to the associated model element in eXpress
• Design Comment Wizard provides structured review and optional auto-resolution within eXpress
• Traceable annotations preserved in eXpressML

Use Cases

• Design Review Cycles — Engineers and reviewers exchange precise, structured feedback without emailing screenshots or ambiguous notes.
• Customer or Field Technician Input — Stakeholders closest to real-world operation can flag issues or suggest improvements.
• Automated Tool Feedback — Software processes can generate eXpressML comments programatically, enabled automated QA or integration checks.
• Digital Thread Governance — Comments can be included in the authoritative model history, supporting audits, sustainment planning, and long term traceability.

Summary

The Redline Module transforms the diagnostic modeling workflow by enabling structured, navigable, and optionally auto‑resolvable feedback from any stakeholder. It strengthens the digital thread, accelerates review cycles, and ensures that every insight—whether from an engineer, technician, customer, or automated tool—becomes part of the authoritative diagnostic model.
