Enterprise
Creates, delivers and maintains
Value while seeking to meet its
Charter and Obligations to its
Staholders
How do we
Support the
Enterprise to
Create and Add
Value ?
How do we

Continue to
Deliver Value ?
Manage, Procure, Build and
Leverage Various Digital
Services to enable the desired
outcomes supporting change
Technology Ecosystem
Drives, Delivers and
Maintains Capabilities that
enable and support the
Organization in its mission
EA

5. Some Additional Perspective
Enterprise Architecture helps support the
North Star Vison of an Organisation
Enterprise Architecture supports how one
builds a reusable Unified Information
Systems/Management Capability that
supports and meets Organisational needs.
The Goal of EA is to Align and Manage the
Technology ecosystem of an Organisation with
its Strategic / Operational Goals/Objectives for
both today and tomorrow.
Enterprise
Architecture is
NOT Enterprise
Systems
Architecture.
Enterprise
Architecture is
NOT a
methodology
for building a
stand-alone
single
information
system.

1.Align and focus ICT and associated activities to
delivering value to the BOM
2.Developing Technology Synergies and cost
efficiencies
3.Promote Re-using System Components
4.Exposing System Services to new processes.
5.Understanding the impact of any change for

The Stack is there to support the
mindset and act as another tick list
