4. • Enterprise Architecture
– Enterprise Architecture is the continuous practice of describing the
essential elements of a socio-technical organization, their relationships
to each other and to the environment, in order to understand complexity
and manage change.

• Enterprise Integration
– Enterprise Integration is about breaking down organisational barriers
and improving interoperability to create synergy within the enterprise to
operate more efficiently and adaptively.
• Enterprise Engineering
GERAM V1.6.3, IFIP-IFAC Task Force, 1999
– Enterprise Engineering is the collection of those tools and methods
which one can use to design and continually maintain an integrated
state of the enterprise.

9. • Human oriented concepts
• Process oriented concepts
• Technology oriented concepts
• GERA Views
10. • Roles & Responsibilities
– Single person more than 1 role
– Responsibilities must be carried out concurrently and cohesively while
reporting to different people using non-aligned control procedures
• Need to capture constructs that promote the use of knowledge
(possessed by humans) in the form of reusable enterprise models
e.g.
– Roles of individuals and groups
– Organisational structures and constraints that are applied to co-ordinate
the roles defined including delegation,reporting procedures, etc.
– The capabilities and qualities of people
However sophisticated and integrated an enterprise can be,
humans will always make the final decision.
11. • Describe the processes in the enterprise
– Functionality (what needs to be done)
– Behaviour (sequence in which things are actually done)
• The process-oriented concepts defined in GERA
– Enterprise entity life-cycle
– Life history
– Enterprise entity types
15. • Technology employed by
– Enterprise engineering process
– Operational environment
• Production oriented technology
– Involved in producing the enterprise products and customer services
• Management and control oriented technology
– Provide communication and information processing and information
sharing
