view in one architecture can be an aspect of the operation view in another
architecture. Situating these aspects in either or is contingent on, among others
Requirements (usability; institutional rules and traditions; etc.) and Design choices made (commission on manufacturing floor; shipment
and installation by experts; operation by experts).The following sections present the IoT Functional View, IoT Information View,
and the IoT Deployment and Operational View of the IoT RA.
4.2.2 Functional view
4.2.2.1 Devising the Functional View
The Functional View builds further on the Functional Model as can be seen in
Figure 31 below.

Figure 31 : Functional view process.In a first step, the Unified Requirements are mapped to the different
Functionality Groups of the IoT Functional Model.
Next, clusters of requirements of similar functionality are formed and a
Functional Component for these requirements defined.
Finally, the Functional Components are refined after discussion with the
technical work packages.
The viewpoints used for constructing the IoT Functional View are hence:
1) The Unified Requirements;2) The IoT Functional Model;
