Virtual reality is most valuable when real-world practice is dangerous, expensive, rare or hard to schedule.
High-risk procedures
Electrical isolation, working at height and emergency response are ideal: trainees can make mistakes safely and repeat a scenario until the correct sequence becomes habit.
Expensive equipment
When the training asset is a production machine, every hour of training is an hour of lost output. A simulator frees the real equipment for real work.
Measure what matters
Good VR training records every step, error and hesitation, giving instructors objective data instead of impressions.
