Bad idea. Onboarding on the fly with no preparation has a low probability of success. An awful lot of things come down to what you want and what you are willing to give up to get it. If what you want is a high probability of success in onboarding, you need to be willing to invest the time and effort to prepare properly.
We saw a lovely movie last night, "Mao's Last Dancer". In one scene, the young dancer has determined that he must build his physical strength to be successful. He has someone make ankle weights for him. Then he has the person make them heavier. "But you won't be able to walk." "I don't want to walk. I want to fly."
Robert Samuelson suggests part of the problem with the current US education system is "shrunken student motivation". In the same article that references this, Thomas Friedman suggests that China and India have a stronger work ethic today than does the USA. Many don't want success badly enough to put in the hours of hard work required to produce it.
Preparation breeds confidence. Practice breeds excellence. Don't onboard on the fly. Earn your success.
