To create the conditions for the most efficient cooperation with customers, an extensive network of regional representative offices of the company has been organized. At the same time, a single information processing system provides an iterative approach to solving customer problems. It involves the continuous processing of all business information with an immediate response to all problems directly in the process. This approach allows you to combine centralized management of all processes and the use of the full potential of the company with individual work with customers in the field. Experience shows that such a scheme of work today is optimal.
