Abstract
An enterprise architecture tries to describe and control an organisation’s
structure, processes, applications, systems and techniques in an
integrated way. The unambiguous specification and description of
components and their relationships in such an architecture requires
a coherent architecture modelling language. Lankhorst and his co-authors
present such an enterprise modelling language that captures the complexity
of architectural domains and their relations and allows the construction
of integrated enterprise architecture models. They provide architects
with concrete instruments that improve their architectural practice.
As this is not enough, they additionally present techniques and heuristics
for communicating with all relevant stakeholders about these architectures.
Since an architecture model is useful not only for providing insight
into the current or future situation but can also be used to evaluate
the transition from as-is to to-be, the authors also describe analysis
methods for assessing both the qualitative impact of changes to an
architecture and the quantitative aspects of architectures, such
as performance and cost issues. The modelling language presented
has been proven in practice in many real-life case studies and has
been adopted by The Open Group as an international standard. So this
book is an ideal companion for enterprise IT or business architects
in industry as well as for computer or management science students
studying the field of enterprise architecture.
