This is a great article! To me this is also about effective delegation. Over and above communicating a shared vision and purpose, I would also be involved in the initial hiring purpose to ensure my purpose or requirement is understood and successfully implemented. This is also a great way of transferring intangible knowledge and insights and helping the other person understand the requirement from my perspective. On my part, I would also realize the ground-level problems faced by the other person while fulfilling my purpose.
