Tim,Sorry. I am allergic to RM tools --- obfuscates system engineering --- so I suggest you contact www.robustdecisions.comJack On Mar 2, 2011, at 3:38 PM, Tim Wilson wrote:
Jack,
This looks like an excellent tool. Can the results be ported to a
RM tool, or is there a requirements management module perhaps?

From my POV, Arun is expanding the scope of ontology
development to knowledge exchange and choice making.
Although this is the right direction there may be a better way of
doing it.
I think the AHP is mathematically flawed. Others do not.
Regardless, it does not help deal with the presence of
uncertainty on the part of the decision makers and does not
leverage the wisdom of crowds. I suggest that interested
parties look at www.accordmanager.com which has not
been publicly announced yet but soon will be.

Hi,
Agreed - in fact any business can be ontologically
decomposed into functional business units and these in
turn into the infrastructure components (including
humans) that enable the business units to
inter-operate. On the other hand, I would like to see
more quantitative approaches integrated with the
qualitative approach because I like to put numbers to
things so I can get a clearer understand what "value"
really means.
For example, on what aspects of ontology (or its
dimensions) should we prioritize effort? How do we
evaluate where we get the most value, the greatest
return on investment in the short term relative to the
long term. I realize everyone likes the long term
benefits that ontologies promise, however, many business
managers would be hard pressed in these economic times
to spend money on the far future as opposed to the near
term tangible and concrete bottom line.
So my hope is to stimulate discussion about what other
models (and I suggest AHP) might be combined with the
ontology framework that is meaningful to a high-level,
non-scientific, business savvy decision maker: that kind
of decision maker is a lot like an investor - they have
a portfolio of options, one of which is more money in
the thing called "ontology" or more money into some
other "thing". Where's the compelling case for the
return on investment. I believe that for any case to be
compelling, it *must* be quantitatively presented in the
hard-bottom line terms that business experts understand.
Hope this is useful food for thought.
Thanks,
Arun

I suggest that an ontology is a key aspect
of the enterprise infrastructure. If architecture is
"The arrangement of function and feature that
maximizes an objective" then infrastructure are the
functions and features that are factored out because
they support all the others. Generally, infrastructure
provides for commonality of location/dimension,
support, access, access control, and services.
Ontology enables human knowledge exchange and choice
making. An EA Framework is one facet of an enterprise
ontology, presuming, of course, that an ontology can
refer to 'itself.'

Hi
Arun,
I believe it is
possible to incorporate Ontology as
an artifact or work product to an
exiting Enterprise Architecture
framework and road map.. I call it
Semantic Enterprise Architecture.
The assessment or the checklist to
find out the readiness would be
another artifact or work product in
the road map as well.. We had some
presentations on Semantic Enterprise
Architecture tools in the past
sessions in this forum.
OAF can be refined to include more
specific information about Ontology.
Or renamed if the other people agree.
At present, some organizations have
a centralized Data Dictionary or
terminology and descriptions, but
there is no consistent understanding
of what comprises ‰Ontology" for the
organization.
Hope that helps,
Pavithra

Revised Strawman Proposal

Hi,
The Ontology Application Framework
(OAF) reminds of the Technology
Readiness Level (NASA's TRL's) that
one could use with another tool,
like an Analytic Hierarchical
Process (AHP) to identify an
ontology dependency and development
strategy for the larger enterprise:
for example, knowing what you have,
what you don't have, and therefore,
what you need to have, would a kind
of "inventory" mechanism that a
document along the lines of this one
might provide. As an industry
developer with clients in the public
and private sector spaces, I tend to
do this similar kind of road-map
work almost semi-automatically for
any new job because I always need
some kind of inventory that serves
the purpose of seeing the client
road map and what the barriers to
success might be.
While the OAF document uses words
like "value metrics" it does not
indicate what methodology is used
whereby qualitative and often
subject judgments are input and
objective numerical evaluations as
outputs (aka value metrics) are
used. My preference is AHP and
other portfolio valuation methods.
The OAF might be the seed for
someone to take it further and a
create a kind of Zachman *style*
framework or model which becomes a
tool for rapid assessment in
strategic road map development, and
therefore, critical and quantitative
budgeting, for the renovation of
legacy enterprises and/or legacy
with new technology integration
paths that are productivity and cost
optimal.
I don't like the acronym "OAF" since
it sounds like the dictionary word
"oaf" ( according to
Merriam-Webster, a big clumsy slow
witted person). Even though my
point seems trite, some critical
managers might find that acronym
disconcerting. And we need all the
help we can get.
Perhaps a name along the lines of
Road-mapping Ontology Model (ROM)
which corresponds also with a
popular acronym for Rough Order of
Magnitude might be useful.
Or perhaps I am just missing the
point entirely?
Thanks,
Arun Majumdar

"Now for this very reason also, applying all diligence, in your faith supply moral excellence, and in your moral excellence, knowledge, and in your knowledge, self-control, and in your self-control, perseverance, and in your perseverance, godliness, and in your godliness, brotherly kindness, and in your brotherly kindness, love. For if these qualities are yours and are increasing, they render you neither useless nor unfruitful in the true knowledge of our Lord Jesus Christ."
