Similar to unconstrained in terms of upgrade, maintenance, and component structure
Operating environment may move through the air
Electrical power, computing and storage capability are limited due to weight constraints
Battery is the primary source of electrical power.
Components are miniaturized and custom-made with special tools to access
No ability to upgrade and maintain system after deployment
Hardware is required to survive in adverse conditions
Limited software control
Real-time sensor inputs and commands
Upgrades and maintenance is not feasible after deployment
Unique system platform that is evolving in maturity as system is being developed
Software Application Difficulties Difficulty would be described in terms of required software reliability, database size, product complexity, integration complexity, information assurance, real-time requirements, different levels of developmental risks, etc.
Productivity Groups may be used to to pre-set COCOMO II Parameters. This is also a work-in-progress.

The proposed approach to classifying software application productivities by Operational Context and Application Difficulties needs to be verified with the government agencies and industrial communities that will use the approach for software project cost estimates.
