Lessons Learned and Special Considerations
• 1st step in any estimate is to define what you’re estimating– WBS is the usual tool cost estimators use to help
define the weapon system• Appendix H of Mil-Hdbk 881A, DoD Handbook
Work Breakdown Structures for Defense Materiel Items, dtd 25 Jul 2005, specifically addresses UAS
• Tailored to match unique elements of systems– Operating and Support costs are defined and
organized according to the six standard CAIG cost elements
Defining an UAS
• Unique 881A Level Two Elements– Air Vehicle– Payload(s)– Ground Segment– System Integration, Assembly, Test and
Checkout• System of Systems approach may be applicable• Integration is an area of concern• Payload(s) and Ground Segment are just as
important (if not more so) than the air vehicle
UAS WBS
• Is Cockpit of UAS, and center of communications and data
• 881A lists Ground Control Systems and Command and Control Subsystem as WBS Level 3 items– GH experience is that Command and Control
Subsystem is a Level 4 element within Ground Control System (GCS)
• Estimating concerns:– Certification and Accreditation– Interface with base comm systems– Interfaces with payloads
Ground Segment
• Payloads are critical - they perform the mission
• Can cost as much or more than the air vehicle
• 881A provides good WBS definition
• Estimating Concerns:
– Size, weight and Power (SWaP)
– Interface with air vehicle’s mission computer
– Interface with ground segment
– End user of payload data may not be part of ground segment and may need separate interface
– Payloads may be common across multiple platforms, which may add schedule and technical complexity
Payload(s)
• UAS WBS is the only WBS in 881A to specifically list System IAT&CO as a Level 2 element– Emphasizes concerns of integrating air
vehicle, ground segment and payloads into one system
• However… GH has not used IAT&CO at Level 2– Integration and Assembly Costs captured and
estimated at Level 3– Test and Checkout costs captured and
estimated in System Test and Evaluation element
System IAT&CO
• GH has a high degree of concurrency in the program– Development, production, and O&S all
happening at the same time– Significant numbers of mods are also
beginning to take place• Complicates estimating– Phasing of estimates is difficult because
schedules constantly change– Be careful of “chasing” technology
Concurrency
• Estimating concerns• Adequate number of test assets– Air vehicles– Payloads– Ground Segments
• Scheduling– Driven by development and production events
Test
• UAS weapon systems are more likely to contain or consist of Non-Developed Items (NDI) /COTS
• Estimating impacts: – Descriptive hardware and software data may
not be available• Limit to government independent technical
evaluation of cost inputs
Proprietary Systems
• Warfighters still refining operations and employment concepts
• Estimating concerns– OPSTEMPO still changing– Basing not finalized• Flexible deployment process
– SATCOM costs– Depots• Subject to 50-50 rule, but proprietary data
reduces flexibility
Operations and Support
• UAS is a growth area• Cost estimators need to be aware of
unique/special UAS concerns• WBS is the basic tool to help define and highlight
areas of concern• Ground segments and payloads are important • Integration between air vehicles, ground
segments and payloads can be a significant cost• Growing applications of UAS will significantly
impact operations and support cost estimates
