Summary:
Enterprise architecture (EA) approaches are widely accepted as a
valuable means in order to enable businesses to gain back control
over their IT systems, to lower costs and to accelerate decision making.
However, even if various authors promise a variety of benefits from
the use of enterprise architectures the real value proposition of
an enterprise architecture remains unclear.
As well as the costs to be invested are only vaguely known by categories,
authors also fail to prove the benefits to be expected in objective and comparable terms.
Therefore withholding the company's management with comprehensible and
reasonable evidence of the EA's value proposition.
Consequently the proposed project aims to establish a value proposition
framework enabling managers to assess an EA approach in an
objective and and competent manner.
As a prerequisite firstly the project will establish a
comprehensive terms and definition framework concerning
the domain under investigation.
Afterwards the value proposition of EA approaches will
be investigated in more detail.
Thereby the project will pay substantial attention to the
different kinds of stakeholders involved.
Finally an EA value proposition framework will be established.
Project details
Significance and Innovation
Although Enterprise Architecture (EA) approaches are widely
regarded as a valuable means in order to lower costs,
to better align business goals and IT infrastructure and
to accelerate decision making the current literature fails
to provide comprehensible evidences concerning their actual value proposition.
Furthermore the term Enterprise Architecture lacks a commonly
agreed definition since the majority of the
authors provide their own approaches.
Last but not least sometimes the idea of an Enterprise Architecture
seems to abused as a buzzword promising the universal solution
to current IT management problems.
In order to disclose the secret of Enterprise Architecture
approaches a scientific procedure is needed to work out
benefits and costs involved, enabling users to deduct the EA's value proposition.
This work supports the evolution of the Enterprise Architecture domain by providing:
- a consistent term and definitions framework
- a systematic and categorized compilation of the costs involved in
and the benefits offered by an EA approach
Therefore it will contribute to a more mature discussion concerning this domain.
Subsequently the area of Enterprise Architecture will turn into a better
understood management topic, providing the management with a valuable
(IT respectively business) governance utility.
The latter will be even more supported by the value
proposition framework to be developed enabling the
assessment of an EA's potential value proposition beforehand.
Approach
Firstly, the project will establish a well-founded
framework concerning the terms and definitions dealt with.
This in turn will enable to conduct and analyse the
results of a world wide survey in a consistent manner.
Secondly, case study interviews will be held at industry partners'
sites analysing the attitudes of the different EA stakeholders in a company.
These will provide the research fundamentals necessary in order to
deduct the costs and benefits involved in an EA approach.
They will also be used in order to prove the research
results found by undertaking literature reviews.
Concluding the benefits and cost instances found will
be based on a consistent basis and compiled into a common framework.
The latter is aimed to be applied easily by any company.
It will enable managers to assess the value proposition
of a current or future EA approach within the enterprise beforehand,
therefore facilitating them to make a well-founded investment decision.
Firstly the project will establish a well-founded framework
concerning the terms and definitions dealt with.
This in turn will enable the project to conduct and analyse
the results of a world wide survey in a consistent manner.
