Multi-level space development is a technique to aggregate detailed scenario or strategy spaces into a more general space. For example, scenario spaces for political development, economic development and social trends in a country may be aggregated into an overall scenario space in which political, economic and social development appear as dimensions. Multi-level spaces are powerful for communicating scenario and strategy planning. For example, they allow zooming in to details without losing the overall picture.

EIDOS also supports multi-level space development through attachments as well as a special preview function.
