Training new hires without becoming their full-time tutor
If training a new hire means you stop working for two weeks, the training system is the problem, not the hire.
Record once, train forever
A 10-minute Loom video of you walking through a process beats explaining it live for the fifth time. Build a library of these as you go. Future hires start ahead of where the last one did.
Pair, don't lecture
New hires learn faster shoulder-to-shoulder with the person doing the job than in a classroom setup. Pair them with your best, not your most available.
Check for understanding by having them teach back
After a week, ask the new hire to walk you through the process. Gaps in their explanation are gaps in your training.
