Cost, Schedule, and Process
Modeling Workshop
USC CSSE Annual Research Review
Facilitated by Jo Ann Lane
Outline
• COCOMO SRDR Calibration Delphi
• Incremental Development Productivity
Decline (IDPD) Delphi
• ISCAS TWINS scheduling model
• Cost, schedule, process modeling future
directions
COCOMO SRDR Calibration
Delphi
• Introduced the planned SRDR calibration
• Provided a view of SRDR in the CSIAC S2CPAT
repository
• Distributed survey asking participants to rate
the “typical” COCOMO parameter ratings for
SRDR types of projects
• Sample size low at this point
• Plan to solicit addition survey responses
Incremental Development
Productivity Decline (IDPD) Delphi
• Conducted review of IDPD hypothesis
• Reviewed
– Analysis conducted to date
– Controlled small project experiments conducted
to date
ISCAS TWINS Scheduling Model
• Scheduling is not one big activity up front
• Need to accommodate discovered risks, new
projects, how best to mitigate risks/issues
• Incremental scheduling and adjustment based
on
– Risks and issues
– Mitigation approaches
– Available resources and associated abilities
Cost, Schedule, Process
Modeling Future Directions
• Cost modeling
– Software cost model updates (medium priority)
– Agile development
– Systems cost modeling for operations and post
development (high priority x2)
– Systems cost model updates (high priority)
– System of systems cost modeling (high priority)
– COTS cost modeling – understanding the mean
lifespan of COTS products and risks when COTS reach
end of life (high priority)
– COTS cost model updates (medium priority)
Cost, Schedule, Process
Modeling Future Directions
• Schedule modeling
– Agile schedules for software development
– System development schedules for operation and
post deployment (high priority)
– System development schedule models, e.g.,
COSYSMO (high priority)
– SoS Kanban scheduling (high priority)
Cost, Schedule, Process
Modeling Future Directions
• Process modeling
– Software development processes (high priority)
– Systems engineering processes (medium priority)
– SoS process modeling (high priority x2)
– COTS process modeling (low priority)
• Other
– NASA data-based research /results across all areas
on the board
