- the profile of the creator and the conditions for the start-up of the enterprise;
- the development of the enterprise's activity, type of clientele, cooperation with other enterprises;
- changes to employee numbers (hiring, dismissals, occasional staff);
- investments and their form of financing;
- training and advice after start-up;
- the difficulties encountered by the enterprise;
- the enterprise's strategy;
- the conditions for its development.

The economic coverage of the Sine programme matches the businesses' demographic scope: all market activities, excluding agricultural activities.

Until the 2002 set, the Sine system only covered the "ICS" scope (Industry, the building industry, Trade and Services).
