This document discusses the importance of enterprise architecture and planning for business solutions. It argues that failing to plan is like planning to fail, and provides examples of how individual systems developed without an overall plan can result in issues like those seen in the Winchester Mystery House. The document recommends defining a conceptual architecture with principles, policies, standards and taxonomy to provide a blueprint or high-level plan before embarking on projects. This helps understand current and future costs and capabilities, and provides a roadmap to transform systems in a coordinated way rather than creating duplicative, incompatible or unsustainable solutions.

“Failing to Plan is

Planning relates to what you intend to build
just like an architect provides the high-level plan for a
new city, or, office block.

Planning individual
systems without regard
to how they work with
other systems
Is like planning of the
Mystery House rooms.
Each room meticulously planned on paper
(even design of the table napkins)
But NO Blueprint or Architect's plans for overall
endeavour
Go Back to Basics
Go back to basics, and have a blueprint
before embarking on major building project.

Project sets off and starts to specify
detailed requirements and design the
solution.
Solution is selected and implementation
project set up with scope, deadline &
budget.
Broad requirement is identified (e.g.
Membership Management, Case
Management).

Irreconcilable tension between
Scope, Time and Money.
This discovery period draws out:
Infrastructure inadequacies e.g. network
bandwidth, porous website security, out-of-
support desktop operating and database
systems.
New interfaces to existing systems for data
requirements.

Unsupportable & Costly
legacy systems
Duplication of systems lead to
duplication of functionality
leading to complexity &
additional cost
Legacy applications persist
and over time become
unsupportable
Users & IT know that much of
the data is the same in
different systems but out of
sync
Members complain
“processes are not joined up”
and different processes exist
Users and systems make
mistakes because every
interface is different
Incomplete

A blueprint is not a detailed specification,
but rather an outline at a
coarse-grained component level.
