This is the
second post in a series on TOGAF’s ADM. In this posting we zoom in on Phase P –
the preliminary phase which prepares the organization for doing architecture
with TOGAF. It may very well be that this is the most elusive phase of the ADM.
We briefly present the objectives, inputs, steps and outputs of this phase
after which we reflect on best practices for this phase.
Objectives, steps, inputs
and outputs.
Formally
the objectives of this phase include a review of the organizational context for
enterprise architecture (EA), identifying sponsors and other stakeholders,
ensuring that everyone who needs to be on board is actually on board, identify
scope and the architecture footprint of the architecture initiative, verify
alignment and define alignment with other frameworks and methodologies as well as
define principles and select supporting tools. A whole list which, in short,
boils down to preparing the organization for doing architecture work by
tailoring the TOGAF framework.
The inputs
of this phase can be split into non-architectural inputs and architectural
inputs. The former are such things as board strategies, frameworks for project
management and governance, budgets, IT strategy etcetera. These inputs entail
the overall direction of the organization. Since it is rare to start from
scratch (green field), architectural inputs include such things as existing
organizational models for EA, existing frameworks, principles and repositories.
Given these
goals and inputs, the idea is that the architecture capability – with the TOGAF
standard in mind – gets to work in defining the scope of the enterprise, and to
make sure the architecture capability is firmly embedded in the existing organization.
This includes obtaining approvals and support.
There are
several outputs of this phase which mainly mirror its goals. The most important
output, however, is the request for
architecture work which is usually sent from the sponsoring organization to
the architecture organization to trigger the start of an architecture
development cycle. This deliverable is one of the key inputs for the next phase
– architecture vision – which is discussed in the next blog posting.
Best practices
In our
experience, the preliminary phase is often underestimated in terms of
importance and complexity. First of all, it should be noted that in doing
architecture work: preparation is everything (note: the author of this post is a firm believer in rule #1 – be
prepared!). Preparation means that people in the organization know what you are
doing, and support the effort. Getting this right avoids the reputation of
being an “ivory tower architect”.
Preparation
also means that the right tools and means of support are in place. No carpenter
would start on an important job without cleaning / sharpening his tools; nor
should an enterprise architect embark on a mission critical to the organization
without taking care of his tools including software, templates, methodologies
etc.
The second
aspect that was mentioned is complexity. We have encountered organizations
where this phase was supposed to be completed in less than 2 days; the thought
being “it’s all there in the book; all we have to do is delete the stuff we do
not need”. In reality, however, there is a lot more to it. For example, at one
large client we saw that executing the preliminary phase for the first time
took close to three months (and involved a team of approximately a dozen
architects), mainly because integration with existing frameworks was a lot more
complex than anticipated.
In our
experience, executing this phase should be a collaborative effort in which all
the key players in the enterprise participate; from business to IT, from
sponsor up to professional on the work floor.
Therefore, we usually follow a workshop approach in which we interact a
lot with people all over the organization.
Typical topics for workshops include the selection of inputs and outputs of phases, integrating the ADM with project management methodologies, or working on the content meta-model and standards information base.
