I need to categorize and differentiate

    Ask The Experts published in DMReview.com
December 2, 2002
 
  By David Marco

Q:

I need to categorize and differentiate "data" tools for our organization. Once the categories are defined, I want to place the tools that are used in our organization into the "map." Surely this has been done before. Does anyone have suggestions for how to begin?

A:

David Marco's Answer: This is a common task that several of our clients have had to deal with. It is important to understand that the information you are asking about (IT portfolio management) is meta data. As a result this IT portfolio management meta data should be stored in a meta data repository. Unfortunately the meta data repository vendors have traditionally not focused on IT portfolio management meta data. Typically we build a custom meta model (physical data model) to store the software/tools. In addition, to storing the software categories it is important to rank the tools in the software categories (i.e., evolving, obsolete, stable and aging).

Before you start building your meta model and capturing this meta data you need to define what your company is going to do with this information. Therefore defining a good project scope for your IT portfolio management effort is the first critical step to your project. For more information on IT portfolio management please feel free to visit www.EWSolutions.com and click on the "Resource Center."
