I am trying to take the first baby steps using PD as an EA
repository. As always, trick is in the establishment of a
structure that works well. Realize this will vary by
enterprise,
but am hoping to locate some good reference models to help.
Does not seem to be much out there from a big-picture EA
perspective. Anyone else having the same issues? Any
resources
out there to help? Anyone like to collaborate and learn from
each other's mistakes? NOTE - my starting point is the
PD-TOGAF
framework.

Yea, it's tough to find good resources other than for
database stuff. For EA it's real easy to hit saturation
fast. I've made a few starts but haven't really found
something that works really well. I've had pretty good
success taking an inventory approach first. I always start
with an enterprise glossary first - communication is alway
key. Then I use a PDM to define a data definition for what
I can. I use Domains to make reuse easy. Next I decompose
the business from a services perspective. The business
website can be a good place to start. For the technology
side I use the System/Subsystem/application decomposition.
Next I create lists of all of the hardware servers and
software servers (e.g., SQL Server, Exchange,etc.)
Somewhere along the line I create a "tech tree" to classifiy
everything (this isn't easy - takes a lot of thought). I do
all of this in the explorer - I haven't built a single
diagram yet. You can to a site hierarchy and orgcharts
(business unit and/or name based(I don't do names)). With
these basic things in place you can start building more
complex things from these pieces. For me the toughest part
is modeling things like server groups. When you have
clusters, failover, virtualization adn all that outher stuff
I end up just giving up. Maybe one day I'll figure out a
good approach. Hope that helps some.
