15th, 2006: Meta Architecture
The following Architecture
of Architectures (for
the definition of architecture: click here) is developed by
me since 1985:
Left one imagines
reality. Because it is a meta architecture for information and IT reality
consists of the organisation and its supporting information infrastructure.
If we take the set of all organisations in the world, we will always
be working for a subset: 1 organisation, a part of an organisation,
parts of more organisations together etc. This is what we call the Universe
of Discourse, the world we are talking about. This world has limits,
and these same limits apply to its supporting information infrastructure.
Part of this information infrastructure contains IT-solutions. These
together are called the IT-infrastructure.
There are many
views on this reality (see
the definition, click here). Comparable views need to be combined
to form relevant architectures. The views of business specialists on
the way the business works is called the business architecture. A number
other architecture can be formed, but they are not really relevant for
the information and IT professionals. The professionals on IT and other
solutions must share their views into an Architecture of the Information
Infrastructure. This architecture contains the IT architecture (technical
IT infrastructure: hardware, network and systemsoftware) and the
Enterprise Architecture (applications/service, data and the alignment
to the business). The support the information infrastructure gives
the organisation can be seen as the business alignment between architectures
architecture is the shared view on the need for information of the organisation
as a corporate resource. The content of this view contains the demand
and can be formulated as specifications for the supply of solutions,
IT or non-IT. Creating a following solution is called development. It
is the process that realises the investments in these kinds of solutions
for the organisation.
This is all. In
practice all kinds of details are added, but in 15 odd years there have
been no concepts and notions that made it necessary to change this picture.
