Top ways to mitigate DMSMS* Risk
* Diminishing Manufacturing Sources and Material Shortages
- Understand the technology roadmap
- Manage the BOM
- Continuously assess your DMSMS management process
- Continuously assess your contractor’s processes
- Collect DMSMS cost and performance metrics
- Analyze the results
- Share data
Diminishing Manufacturing Sources and Material Shortages (DMSMS)
(DoD Definition) The loss or impending loss of the last known manufacturer or supplier of raw material, production parts or repair parts
(Industry Definition) The loss or impending loss of the original manufacturer or supplier of raw material, production parts or repair parts
Obsolete Part: A part of a larger system that is no longer manufactured by the original manufacturer
DMSMS Impacts
Microelectronics - 83%
Other - 17%
Bearings Fiber Optics
Semiconductors Tubes
Switches Fire Control
Connectors Radar Equipment
Resistors ADP Equipment
Capacitors Antennas
Circuit Cards Electronic Modules
Factors Driving Microelectronics DMSMS
Prime Driver of DMSMS Situation - Commercial Profit Motive: When a part is no longer economical to produce, manufacturers will move on to more profitable items.
The Commercial Profit Motive works against the military for two reasons:
Diminished Overall Demand:
Military customers “require” specialized parts (i.e., temp, voltage)
Commercial microcircuit users (computers, cell phones, etc.) now constitute—by far—the largest share of the market
Military share of the microcircuit market:
1975: 17% 1985: 7% 2002: ~0.3%
Extended Support Periods:
Microcircuit life cycles average ~18 months (much less for memories)
DoD has long design-to-acquisition lead times
Extension of the service lives of systems
Support requirements for military systems outlast those of parts
Commercial electronic systems: 4 – 7 years
Military electronic systems: 25 – 30 years
Traditional Logistics Support
Time and material contracts
Contractor paid as service is delivered regardless of impact on warfighter
Government owns all of the performance risk
Under defined or lack of defined scope
No investment by contractor beyond that paid for by government
Government sunk cost in materials
Government owns the results if they accept the product or service
Contractor gets paid for correcting deficiencies he may have created
Government responsible for mitigating obsolescence issues
No incentive to introduce improvements
PBL represents a state change
Focuses directly on meeting warfighter defined goals
Shifts weapons system lifecycle sustainment responsibility to the PM
Payment based on results not delivery
Fixed price per unit of output
Performance Metrics driven incentives and penalties
Long term contracts
Contractor profits based on level of risk sharing
Implicit assumption that the contractor will invest in infrastructure and inventory
Freedom to execute the work the most efficient manner
Oversight based on performance metric results rather than inspection, cost and pricing
data certification, etc.
Incentive to improve reliability to lower operating costs
Incentive to upgrade to maintain product viability
Simplifies financial transactions
Performance Metrics
Material Availability
Number of End Items Operational / Total Population of End Items
Material Reliability
Total Operating Hours / Total Number of Failures
Mean Downtime
Outcome Based Assessment Focused on Goals and Variances from Goals
