Advice to Senior Management

explain to people what your career path plans are for the individual (respond to all internal job applicants, even if negative) - I know 3 people who chose to leave the company because they applied for an internal job and never heard anything; in most cases the reason for not promoting would probably have been enough for the individual to understand and accept.
