Remote Virtual FAT Evidence Portal
Turn PLC-linked twin sessions into reviewable scenario evidence, open-issue workflows, and traceable customer acceptance
Our role
We designed the evidence model, session capture, build and mapping traceability, issue workflow, replay experience, and customer acceptance portal around PLC-linked twin testing.
The Problem
Virtual FAT sessions often depend on everyone joining the same live call and interpreting the same screen share. Scenario status, controller and model builds, mappings, evidence, comments, and acceptance decisions become fragmented across meeting notes and file shares.
- Pass, fail, blocked, and open-issue states are not consistently tied to the exact scenario execution
- Evidence loses technical context when PLC builds, twin builds, I/O mappings, or configuration snapshots change
- Customers in different locations cannot review, comment, and accept results asynchronously in one traceable workflow
Why It Matters
Virtual FAT only supports delivery confidence when reviewers can prove what ran, against which builds, with what result, and how every issue was resolved. Replayable evidence lets acceptance continue beyond the live session.
- Traceability from scenario execution to build identities, mapping snapshots, and review evidence
- Visibility and closure quality of failed, blocked, and open-issue scenarios
- Readiness of customer reviewers to assess and accept results asynchronously
Our Solution
Session workspace connecting PLC-linked twin runs to named scenarios with pass, fail, blocked, and open-issue status
Execution record containing controller build, twin build, sold configuration, I/O mapping snapshot, participants, and timestamps
Replay evidence package with synchronized recordings, event traces, expected behavior, observations, and reviewer comments
Asynchronous customer review workflow for questions, issue linkage, retest evidence, approval, and acceptance history
Results
Live virtual FAT calls followed by scattered recordings, issue lists, build notes, and customer approvals
Evidence portal where each scenario, technical baseline, replay, issue, retest, and acceptance decision remains connected
- Reviewers can assess test outcomes without relying on memory or attendance at the original session
- Retests preserve the relationship between the issue, changed build, new evidence, and closure decision
- Customer acceptance has a durable audit trail that supports physical FAT and project handover
Project context
A machine builder conducting remote virtual FAT needed more than meeting recordings and a shared issue list. neexo connected scenario execution to controller and twin baselines, packaged replayable evidence, and created an asynchronous review and acceptance flow for project teams and customers across locations.
Deliverables
- Virtual FAT scenario portal with execution status, technical baseline, participants, and evidence records
- Replay package linking recordings, event traces, mapping snapshots, observations, and open issues
- Customer review, retest, approval, and acceptance workflow with durable traceability
