Collaboration is not directly represented in SysFEAT.

Rational:
Collaboration is represented as a composite Agent in SysFEAT

External Active Structure is not directly represented in SysFEAT.

Rational:
SEA
F does not differentiate between internal and external active structures, as the External Active Structure classification contains only one subtype: Interface. Instead, SEAF focuses on two interface types: the provider interface for service delivery and the requester interface for service consumption.

External Behavior Element is not directly represented in SysFEAT.

Rational:
SEAMF does not distinguish between internal and external behaviors. The classification of External Behavior Elements is redundant, as it contains only a single subtype: Service.

Function is not directly represented in SysFEAT.

Rational:
ArchiMate's definition of Function as a collection of behaviors lacks sufficient distinction from its definition of Process. SEAMF addresses this by introducing the concept of Process Family - a classification category rather than a behavioral element.

Internal Behavior Element is not directly represented in SysFEAT.

Rational:
SEAMF does not distinguish between internal and external behaviors. The classification of External Behavior Elements is redundant, as it contains only a single subtype: Service.

Structure Element is not directly represented in SysFEAT.

Rational:
SEAMF employs a unique methodology to categorize functional assets (known as elements in ArchiMate). In this framework, the differentiation between Passive and Active structures is context-dependent. An object can assume a passive role in one process, serving as the subject of transformation, while acting as an active agent of change in another.
