Enterprise Architecture Framework

An Enterprise Architecture Framework need to be very accessible.
I have found that find the original Zachman Framework matrix can be too complicated for some people.
In most cases I find that people accept the columns based on the six questions, who, what , where, how, when and why.

The column names are not always understood.
There is confusion about all the rows and in which cell to put the ings such as User Interfaces, Use Cases, Objects, Classes, Components and Services.

The original Zachman Framework betrays its Information Engineering legacy and needs updating.

Does a class belong in the Data or Function Column ?
Where does a Service belong ?

If we distinguish between an organisational service (performed by people) , an application service (performed by a software application) and an infrastructure service (performed by the hardware and infrastructure platform), then should we put each of these services into a different column ?

How do we map strategy aspects and the architecture discipline ?

In response to this I have created a matrix with two dimensions:

  • Levels of Abstraction {Strategy, Architecture, System and Operations}
  • Architectural Perspectives {Information Architecture, Process Architecture, Application Architecture, Technology Architecture, Organisation Architecture and Performance Architecture}

I have found this to be more aligned with organisation view points and common terminology.

Make no mistake: Our mission at Tip Top Equities is to sift through the thousands of underperforming companies out there to find the golden needle in the haystack. A stock worthy of your investment. A stock with the potential for big returns. More often than not, the stocks we profile show a significant increase in stock price, sometimes in days, not months or years. We have come across what we feel is one of those rare deals that the public has not heard about yet. Read on to find out more.

Nano Superlattice Technology Inc. (OTCBB Symbol: NSLT) is a nanotechnology company engaged in the coating of tools and components with nano structured PVD coatings for high-tech industries.

Nano utilizes Arc Bond Sputtering and Superlattice technology to apply multi-layers of super-hard elemental coatings on an array of precision products to achieve a variety of physical properties. The application of the coating on industrial products is designed to change their physical properties, improving a product's durability, resistance, chemical and physical characteristics as well as performance. Nano's super-hard alloy coating materials were especially developed for printed circuit board drills in response to special market requirements

The cutting of circuit boards causes severe wear on the cutting edge of drills and routers. With the increased miniaturization of personal electronics devices the dimensions of holes and cut aways are currently less than 0.2 mm. Nano coats tools with an ultra thin coating (only a few nanometers in thickness) of nitrides which can have a hardness of up to half that of diamond. This has proven to increase tool life by almost ten times. Nano plans to continue research and development into these techniques due to the vast application range for this type of nanotechnology

We believe that Nano is a company on the move. With today�s steady move towards miniaturization we feel that Nano is a company with the right product at the right time. It is our opinion that an investment in Nano will produce great returns for our readers.
