Project-based assignments expand networks and capabilities. A healthy organization encourages all types of internal movement.

Post all positions internally first, create transparent career paths, invest in skills development, encourage rotational programs, reward managers who develop talent for the broader organization, and use talent marketplace technology to match employees with opportunities. Following these guidelines will help ensure accurate results and better outcomes over time.
