There are several considerations to take care when you decide to go for one or other type of training:
-Object of the training: Virtual works fine with software, but when you go for physical devices, specially when they have fine adjustments, physical presence cannot be replaced. For procedures and similar, LMS is an option.
-Travel options for trainees. If you have trainees from a single location, physical makes sense, but if there’s people from all over the world, sometimes you need to be more flexible. Recent pandemy showed us some hybrid solutions. For us, hybrid training (trainer via vÃdeo to show procedure and solve doubts and co-trainers – expert senior FSE’s – locally to show trainees the physical part) worked fine, even with complex devices.
-Mixed options. You can use LMS for theory and physical training for practical part.
-VR. Not sure about the maturity of this tech for training. It can help for simple parts, but sometimes you need to feel the real thing, like how much tenths of a turn you need for a fine adjustment. I think this can help in the future to simplify trainings, but not completely replace the physical training.
