7:30 a.m. I’m at the Hyatt in Cambridge, MA overlooking the Charles River with teams of students rowing to perfect their stroke and timing for competition. Just down the river Boston is coming to life as thousands flood the city to start their day. Joining me this morning are roughly 100 executives and senior managers gathered to discuss pressing business challenges that arise when bring new professionals into  their organizations and learn how to improve retention and accelerate productivity of new employees.
