The log is only one layer
Many embedded test workflows produce a result file, a console log, or a report. That output can be useful, but it rarely tells the whole story. A reviewer still needs to know how the stand was configured, which versions were used, what the operator changed, and whether the result can be repeated.
Trusted evidence is the chain of context around the result.
What the evidence pack should preserve
For one workflow, start with these categories:
- Stand and fixture setup.
- Device, firmware, script, and tool versions.
- Environment assumptions.
- Test sequence or script entry point.
- Run logs and pass/fail reason.
- Screenshots or generated reports when they add context.
- Operator notes and known anomalies.
- Reviewer decision or follow-up action.
The goal is not to create paperwork for its own sake. The goal is to make the result understandable after the person who ran the test has moved on.
Where evidence usually breaks
Evidence gaps often appear at handoff points. A LabVIEW step may depend on a manual setup. A TestStand sequence may call a script that has its own version assumptions. A HIL setup may use simulation parameters that are not captured in the final report.
When context crosses tools or people, it needs a deliberate handoff.
Quick self-check: evidence pack readiness
Pick one workflow you own. For each category, score your current state.
| Category | Weak (1) | Adequate (2) | Strong (3) |
|---|---|---|---|
| Setup context | Nobody records stand config, fixture state, or operator choices. | Setup is documented but stored separately from test results. | Setup is captured automatically and linked to each run. |
| Version traceability | No record of firmware, script, or tool versions used in a run. | Versions are in a wiki or notebook, updated occasionally. | Every run logs versions of all tools, scripts, and firmware. |
| Run evidence | Only a pass/fail line in a spreadsheet. | Logs exist but must be found across tools and folders. | All run data is stored in one accessible place with run ID. |
| Handoff clarity | Nobody knows who set what between tools. | Handoffs are known but not documented. | Each tool-to-tool and person-to-person handoff is explicit. |
| Review context | Reviewer sees only the final report. | Reviewer can request logs but it takes time to assemble. | Reviewer has setup + run + anomaly context in one package. |
How to read the score:
- 5-7: Your evidence chain has serious gaps. Start with the diagnostic kit on one workflow â free, 30-45 minutes, no data shared.
- 8-11: Evidence exists but is scattered. A workflow review can help decide which gap to fix first.
- 12-15: Your evidence practice is strong. A paid diagnostic might still find automation opportunities, but the basics are covered.
This is a thinking tool, not an audit. Use it to decide whether one workflow is worth mapping more carefully.
