Traditional System Based Procurement
MILES XXI
MILES WITS MILES TVS
• Currently, the complete TESS system is purchased
3MILES IWS
System Based Procurement Consequences
• System component interfaces are proprietary
• System software is proprietary• Components don’t interoperate
TESS Master Controller
Proprietary
4
Problems: System Based Procurement
Product Manager for Live Training Systems (PM LTS) purchases a complete TESS kit
Incumbent vendor difficult to unseat due to proprietary interfaces Each vendor implements TESS master controller functionality
Results High sustainment cost Low competition Low innovation due to no Government R&D dollars
Dependent on contractors' IR&D funding for innovations Master controller behaviors aren’t consistent between systems
5
Solution: Component Based Procurement
• System component interfaces are open standards
• System software is Gov’t owned and reusable
MCCStandard
6
Component Based Procurement Details
Product Manager for Live Training Systems (PM LTS) purchases components which interoperate through government managed standards
Vendors re-use government developed TESS master controller software
Results Lower cost due to re-use and ability to acquire only necessary
components More competition because of published interface standards Consistent master controller behavior

Live Training Engagement Composition (LTEC) Vision
Provide common government owned TESS master controller software
Goals Reduce development and procurement costs Integrate with various hardware configurations Enable adapting quickly to new and changing requirements Mature and promote interface standards Enable interoperability between components
