The right people
When the right people are not in the right jobs, the problem becomes visible and clear quickly. Systemic processes, tools and accountability measures cannot produce results like the right people can.
Right people cannot be found by the mere desire nor by the extreme need to bring them on. By the same token, the best of people thrown together on the job with little direction and little mentoring cannot bring you the outcome you expect.
Great outcomes result from great teams. It is essential to have the right people in the right jobs. And it takes immense personal commitment on the part of the leader to build such a team. It takes time, energy, tactic and genuine investment in each person. It is fraught with emotional wear and tear and a constant need to prove your unflinching soundness of judgement and reasoning.
The foundation of a great organization is the team. A great team is when the right people take up the right job. You are a part of that team.
