More on Federal IT spending

Recently I discussed several areas that need to be focused on it one really wants to get a handle on Federal IT spending.  Today I want to expand on my thoughts and talk about  collaboration and sharing of IT investments.

In order to reduce IT within the government collaboration will need to be achieved.  This is a simple concept, (i.e. exeryone works together and shares their solutions) but is difficult to obtain.  Why is id difficult to obtain?  My opinion is that the Federal IT community trys to go for programs and initiaitives that are just too big.  The newest thoughts on cloud computing, for example, would imply that agencies would share the same infrastructure.  A difficult task at best considering most agencies have invested 100 of millions of dollars into infrastructure projects.  an example of where collaboration has worked is the Budget Formulation and Execution Line of Business (LOB).  This LOB has been able to collaborate and share solutions because they kept their goals and inititives focused and achievable.  I am currently working on ideas for keeping solutions achievable but would be interested in any ideas.
