This changes considerably, if storyboards are interpreted operationally [6].
Figure 3 illustrates some storyboard in use for training teams of executive staff
in civil protection and disaster management (see [6] for background and details).
The Excel file next to the storyboard contains text components assigned to
particular nodes of the storyboard.

One may imagine the work of the digital system based on this storyboard
roughly as follows. The system is running on top of the storyboard beginning on
some initial node. When the system enters some node, it is reading the semantics
of the node and performing an action accordingly. If the node has a pointer into
the relational database on display next to the storyboard, the system is reading
the content unit to present it to the human user. If the node is a branching point,
the system presents options of choice such as different buttons, e.g., to the user.
According to the storyboard structure and to the user interaction, the system
traverses the storyboard from one node to the other.
In some sense, the underlying storyboard is directly executed by the system-
be it a digital game, an e-learning system, or whatever-running on top.
As demonstrated by Knauf et al. [21], substructures of such a storyboard
may contain or represent didactic knowledge. Having the storyboard separated,
to some extent, from the digital system interpreting it, allows for modifica-
tions. Running on some modification means the direct execution of educational
memes.
