The global market projects companies in a very large competitive scale where it is hard to excel as a single unit, so it's always more useful to organize as part of a system in which to develop synergies, collaborations and fill internal gaps. The "Vistra method" is based on an efficient team organization, with qualified and experienced consultants, who help the company to manage and deliver the requested service. So the company can concentrate on its own core business, monitoring the activities of the team, evaluating performance and objectives.
