We learn from strategic writing
teacher Mr. Barr that
we should make the communication process simple thus can make the receivers
easy to understand. In the communication between business department and IT department,
we should also keep the process simple.
But what is the condition now?
What
are CIOs thinking?
Cynthia Rettig wrote in The Trouble with Enterprise Software that,
the CIOs and their managers try every
effort to prove the value of IT to the business side of the organization. Yet, the
cost overruns, delay and outright failures of enterprise systems have if
anything widened the digital divide between IT and the executive suite.
What
are CEOs thinking?
Nowadays, CEOs are finding that they cannot
understand what the CIO teams are doing. As Shay said
in 2007, only 28% of CEOs thought their CIOs were proactive or creative in terms
of business process improvement. It seems that CIOs are in a really hard
time.
All the problems seems point to
the mechanism between business dept. and the IT dept. The managers and
employees in each department cannot understand what guys do in the other. When
this kind of thing happens in the core management layer, it will lead to a really
bad ending.
My first job was at a company
contains only 50 people. The CEO was an MBA graduated from Yale. She thought
that the IT team in our company was not dependable. And can you guess what the
reason was? Once, she asked an IT guy who was charging the company website to
help her to fix her laptop. Unfortunately, the guy cannot solve the problem. In
the end, the CEO wanted to fire that person and said that, ”he could not even
fix my laptop.”
Why a person in charging website
must know how to fix a computer?
This is what the CEOs are
thinking.
How
to solve this communication problem?——EA
Besides improving the basic
communication skills of the both sides, to build up a fixed pattern for them to
communicate with each other is a natural solution.
Considering this, John Zachman
proposed the Framework for Information Systems Architecture in 1987, which was
regarded as one of the creative discovery in Enterprise Architecture.
Except Zachman’s Framework, there
are some other Framework models: e. g. NIST EA model, FEAF, TAFIM, and TOGAF.
Communication
methods in EA building
So, what we should do in building
the EA?
We should link different department
(especially IT department and business department, which is of the most
important) together into a whole.
Zachman
wrote in the foreword of An Introduction to Enterprise Architecture 3rd
Edition (pp. 7-9)
that Enterprise Architecture is not well understood. It is treated as an I/S or
IT issue, or I/S management, or a kind of academia.
EA
is the analysis and documentation of an enterprise in its current and future states from an integrated strategy, business, and technology perspective——An Introduction to Enterprise Architecture 3rd
Edition (pp. 31)
What I want to emphasize is, it
is not a simple definition, it is an organic whole of strategy, business, and technology.
As is shown in the Cube on the right.
“It is the Issue of the Century”,
Zachman wrote.
It
is quite easy to find out from the Figure above that, what we should do is analyze
and find out how the enterprise do currently in the 5 aspects ( goals & initiatives,
products & services, data & information, systems & application, networks
& infrastructure) and what we want the enterprise to be in the future in
the same 5 aspects.
When I was at work, I learned a
basic thing in business and also suitable in every part of our life. Guess what
it is?
It is Necessity Thinking. Thus, we can find out the shortest way to our goal.
For example, suppose we know there are five elements that can affect whether the
customers will choose a product (e.g. price, function, color, popularity, and
size). After finding from statistics, we find out that it is the price that the
customers most care about. All the other four elements are not so important. So,
the price is the essential condition. Then, we should do every effort to lower
the price. If we have time to improve the other four element, we do the
improvement; and if the time is limited, we should focus on the price. This is
the most efficiency and economical way to solve the problem.
To find a shortest way to make
the transition from the current architecture and future architechture, the
necessity thinking is quite important.
There should be some obstacles in EA. Let's find them out in the future.
PS: http://eapad.dk/ea3-cube/overview/ this page is really good to have an overview of the Cube.
