3\. Paragraph B.3.1, CSOC Initiated Projects, contained in FSA B.3,
Development Engineering Services, is deleted in its entirety and
replaced with the following:

####### B.3.1 CSOC Initiated Projects

## CSOC Initiated Projects are those projects adopted by the program to increase program efficiency and decrease overall program cost by developing an upgrade to the Integrated Operations Architecture (IOA). Current CSOC Initiated projects include:

-   FDF Enhancement

-   PACOR Automation

-   Data Services Management Center

-   Data Services Automation

-   Mission Data Storage Consolidation

-   DSN Enhancement

-   CSOC Integration Center

Additional CSOC Initiated Projects will be identified through issuance
of Delivery Orders in accordance with Attachment J-18 in the contract.
Implementation of the CSOC IOA relies on a number of NASA initiatives.
These interrelationships are depicted below. Failure by NASA to complete
development initiatives as scheduled will impact IOA development and may
cause changes in contract content and value.
