Agree with much that has been said, and very interesting to read all of this. Similar to what others have already said I would emphasize to importance of identifying the key talent during the due diligence phase and prepare concrete actions with regards to motivating and keeping that group of staff. Not everything needs to be solved through financial incentives. In particular young people react well to new career opportunities and expansion of responsibilities. But the challenge is to communicate effectively and tailor the messages to the various groups of employees and not just send out standardized messages to everybody.
