Talk the Apprentice Through It or Drive Out Yourself: Decision Tree
Why this matters
The apprentice is stuck on site, the customer is waiting, and you are on another job. You can talk them through it or you can get in the truck. Guess wrong in the cheap direction and you burn an hour coaching a check that needed your hands, then drive out anyway. Guess wrong in the expensive direction and you abandon a paying job to do something a phone call would have solved. This is a judgment made under pressure with money on both sides, so it pays to make it on a fixed set of factors instead of a gut feeling.
Start here: the safety gate is not a factor, it is a stop
Before you weigh anything else, one condition ends the debate.
- If the decisive next step is unsafe for their training level - stored energy, live conductors, gas, pressure, height, or a confined space they are not qualified for - you do not coach them across it to save a drive. That is a drive-out or a hold, full stop, regardless of distance or cost. Talking a green hand into a hazard is the one wrong answer that can hurt someone.
Only once the remaining work is safe for the hand on site do the factors below apply.
Weigh it on six factors
| Factor | Points to coaching remotely | Points to driving out |
|---|---|---|
| Helper skill | Trained on this exact check | Green, or never done it |
| Complexity | One clean splitting reading | A judgment call or a long sequence |
| Reproducibility | Fault is present and steady | Intermittent, will not hold still |
| Cost of a wrong call | Cheap part, reversible | Condemnation, big part, or safety |
| The decisive observable | A number or a clear visual | A subtle feel, smell, or flame color |
| Distance and your job | Far away, your job is billable | Close, your job can pause |
No single row decides it. Read the balance: three or more rows leaning the same way is a clear call. A split usually means try a bounded remote attempt first, then drive if it does not land.
When to pick which
Coach remotely when the hand is competent for this check, the fault is present and steady, the decisive observable is a number or a plain visual, and a wrong answer is cheap to reverse. A capacitor value, a voltage present-or-absent, a valve position, a clogged-or-clear - these transmit cleanly and cost little if you have to re-check.
Drive out when the call turns on a judgment reading your senses have to take, the fault is intermittent and will not reproduce for them, the wrong answer condemns an expensive component, or the hand is past their depth on the one step that matters. A subtle bearing feel, a flame color, a faint smell, a "sometimes it does it" - none of those survive the phone.
Hold or reschedule when neither is right today: the step is unsafe for them, you cannot leave your current job, and the fault can wait without harm. An open ticket beats a wrong call or an abandoned customer.
Set a time box on the remote attempt
If you choose to coach, do not let it run open-ended. Give it a bounded try - a couple of splitting checks - and name the stop condition out loud: "if we can't trust the reading after two tries, I'm driving out." The trap is the sunk-cost creep where twenty minutes of coaching turns into an hour because you have already spent twenty. Set the limit before you start.
Recap
- If the decisive step is unsafe for their level, drive out or hold - the safety gate is not weighed, it stops.
- Score the call on skill, complexity, reproducibility, cost of error, the observable, and distance.
- Coach steady faults with clean observables and cheap errors; drive for judgment reads, intermittents, and expensive condemnations.
- Hold when it is unsafe and can wait.
- Time-box any remote attempt and name the stop condition first.
