This is a period of time during which you'll be elaborating a project along with a personal manager assigned to you. The manager helps to define a goal, answers your questions and configures a scenario for you. This period of time includes initial setup, collaborating and approval: routes, texts, integration data, audio records, etc.
For example, you order elaboration of a large scenario. On Monday you meet or call the manager. The next 15 days the manager will work with you, i.e., your active participation in the project will be required.
