.
Program Manager:Mr. Desi Dundics 
Project Staff:Team composition varied with task requirements. Mr. Dundics was Project Manager for entire project, and RCM, CMMS and Metrics specialists participated as required for each task.
Team size varied between 2.5 FTE to 4.5 FTE (Full Time Equivalents)
 
 
equipmentLinks Contract History With DSN

Desi Dundics and equipmentLinks was first introduced to the DSN in 2002 when asked to perform an RCM assessment at Goldstone, and then again in 2003, 2004 & 2005 when he led teams at both JPL and Goldstone to inspect the facilities for the Deferred Maintenance (DM) Program. These DM inspection program replaced the long-standing Backlog of Maintenance & Repair (BMAR) programs. In 2006 he was then contracted to support DSN as the Executive Consultant to embark on a new initiative to implement RCM and an improved asset management process. This would require a challenging and significant culture change for the organization.

The initiative started by defining the future vision of the asset management program and a strategy for getting there. This required an initial assessment at all three site locations, Goldstone, Madrid and Canberra, which identified their strengths and weaknesses and which helped define the path for arriving at the future, common vision. The next five years would be extremely exciting, filled with technical learning experiences and opportunities to interface with some of the brightest people in the fields of aeronautics and space exploration. This project helped the team at equipmentLinks not only to become extremely familiar with the technical issues of an antenna, but also to understand and overcome the challenges of implementing change at a Government facility. This has been an invaluable and unforgettable experience.
