Robot Deployment Failure Investigation: Evidence to Verified Resolution

A deployment failure is not resolved when the robot “starts working again.” It is resolved when the failed acceptance condition is identified, evidence is preserved, a cause is confirmed, a change is authorized, and retest shows the original condition no longer fails. This guide is the investigation path Dagmont expects teams to follow inside Deployment Intelligence—useful even if you track the same chain in another system of record.

Stabilize and preserve, then define the failed condition

First protect people and process per site rules. Then preserve volatile evidence: logs, video, config snapshots, mission IDs, versions. Write the failed requirement in operational language (“recovery after blockage exceeds 90 seconds at aisle R12 during peak inbound”), not only a symptom label (“AMR stuck”).

Without a failed condition, retest has nothing to prove.

Evidence before opinions

Collect primary artifacts with timestamps and identifiers. Record missing evidence explicitly. Separate observations from hypotheses.

Premature cause statements contaminate multi-party reviews between manufacturers, integrators, and customers. Attach environmental context: traffic, lighting, layout changes, integration load.

Confirm cause; reject silent workarounds as closure

A confirmed cause names a mechanism that explains the evidence and predicts what change should work. Narrowing an operating zone to avoid a bad aisle may be a temporary control, but it is not verified resolution unless accepted as a formal limitation with residual risk. Document workaround vs root-cause fix explicitly.

Corrective action and retest against the original condition

Map the change to the cause. Capture authorization and the new baseline. Retest the original failed condition under comparable site pressure.

If retest is deferred, leave the acceptance condition open. Symptom disappearance after an unrelated restart is not verification.

Close into acceptance and future reuse

Link the verified resolution to the acceptance decision. Keep the chain available for warranty and for the next site. Cross-deployment learning is only safe when the prior cause and verification method are explicit—not when teams copy folklore.

Checklist

  • Write the failed acceptance condition before debating fixes
  • Preserve primary evidence with robot, site, and version identifiers
  • Separate observations, hypotheses, and confirmed causes
  • Authorize changes and record the new baseline
  • Retest the original failed condition
  • Link verified resolution to acceptance or explicit conditions
