naming or numbering of the components, description of the process task, classification of the process relevance, and other designations that help in understanding their
role in the DTMS. For these instructions, all the existing process descriptions are
beneficial. Exemplary records are flow charts, SCADA-charts (Supervisory Control
and Data Acquisition), illustrations from management systems, and results of laboratory management systems.
3.5 Composition of the Big Picture
The big picture provides the DTs’ structure and architecture and comprises the
DTMS as well as its connectors, functions, and the necessary physical model and
data model. It is an integrated complete high-level vision of the “To-Be” system,
depicting the desired future operation. It considers current trends (e.g., digitization),
historical social perspective (e.g., consumer demands), economic perspective (e.g.,
influence of the market), and forecast (e.g., influence of artificial intelligence; effects
of robots) as well as own objectives.
