To convince managers to support an EA
initiative, I think it's the value that EA can offer that matters the most,
because business is all about benefit maximization. I read an example of Nokia
trying to use the Nokia Siemens Networks as a key business competitive
advantage in areas such as network management, customer experience, charging
and billing. In this case, Enterprise Architecture can raise new opportunities
and capabilities in each different aspect.
In the business point view, EA handles
the value chain aspects relevant to the business as a whole: where to improve
the business efficiency and develop new value propositions and how to increase
efficiency and competitiveness of the business in the context of its
environment: markets, competitors, legislative and environmental aspects,
influences and impacts.
For the process viewpoint, Nokia
Siemens Networks Process Architecture is based on best practices applied with
hundreds of customers, and focuses on customer insight, experience and management.
It has been especially designed to cope with future requirements of network
architecture, and for different business models, such as Network
Provider/Service.
For the information viewpoint, The
Nokia Siemens Networks includes the modeling of information entities, their
attributes and their inter-relationships, and also additional aspects such as
data ownership, master data management, metadata repositories, and distribution
of data stores. It shares information and data Model for applications and
solutions
For the Technology viewpoint, it addresses
the selection of platforms, middleware, and infrastructure along with issues of
relevant standards. This includes the communication infrastructure and IT services,
the strategy for selecting HW and SW platforms, operating systems, and
middleware and programming languages.
In conclusion, the
EA analysis benefits the system implementation in following ways:
1.
improve
agility
2.
improve
operational efficiency
3.
improve
customer satisfaction
4.
assure
business continuity
5.
decrease
the total cost and accelerate procedures.
