The 45-minute case becomes a 45-second review
A short field note on what changes inside the diagnostic engineer's workflow on day one of running on the intelligence layer.
By David Nalder
The first thing that changes is the case open.
Before: 45 minutes of context-gathering. Pull the DTC log. Pull the work-order history. Search the knowledge base. Cross-reference the telematics. Read four prior cases that might be related. Then start thinking.
After: 45 seconds. The reasoning is already assembled. The relevant prior cases, ranked by similarity. The hypotheses, with confidence scores. The evidence behind each. The remote tests that have already been run.
The engineer's job is no longer assembling context. It is judging the reasoning that was assembled for them. That shift — from gathering to judging — is what makes the rest of the numbers move.
