Sustainability
One of the most challenging aspects of using consultants is to keep up the momentum. Change has a tendency to want to shift back to the way things were if not managed properly. Many times consultants deliver fantastic results while engaged with their clients, but focus and direction are lost when the contract ends. They fail to train and enable their clients to maintain the results long-term. The best consultant is one who works themselves out of a job allowing their clients to take the reigns and succeed on their own.
